Crafting the perfect essay takes time and dedication. There are so many elements you have to worry about, such as tone, purpose, and correct spelling and grammar. Writing a strong topic sentences is another critical part in writing a cohesive essay. 

Without a strong topic sentence, you risk losing your reader and perhaps part of your grade. If it’s a college admissions essay, then you need it to be as strong as possible to back up your application. Learn about what steps you should take to write a strong topic sentence.

What Is a Topic Sentence? 

People often confuse a topic sentence with a thesis statement. A thesis statement is typically at the end of your opening paragraph, that dictates the main argument you’ll be making in your essay. 

Throughout your essay, you’ll have multiple topic sentences, as each paragraph should start off with one. This beginning sentence is used to direct the topic of the paragraph and outline the flow of the following sentences. It’s used to help guide your reader and to continue to keep them hooked on your overall essay. Without topic sentences, your essay will be unorganized, lack transitions, and sound very choppy. To write a good topic sentence, there are several steps to take.

Writing a Good Topic Sentence: 5 Steps

Step 1: decide what you’re going to write about..

When you see the essay prompt, you’ll have some time to think through what you want to say and why. You have to decide if it’s a persuasive essay, informative, narrative, or descriptive. Determine your purpose for writing the essay after reading through the prompt. Whether it’s an assignment for school or if it’s to get into college, you need to make sure you have that purpose clearly outlined. 

Step 2: Create a thesis statement.

One of the first things you need to do is create a thesis statement. This is typically a sentence with three points that you’ll back up throughout your essay. 

For example: The Office became a cultural phenomenon because it spurred the careers of many of today’s successful movie stars, it talked about situations that most American workers can relate to, and even 15 years later, offers funny, relevant content that helps to break down prejudices. 

You then use that thesis statement to create an essay around the points you want to make. 

Step 3: Make your essay outline.

Once you have the points you want to make within your thesis statement hammered out, make an outline for your essay. This is where you’ll start to create your topic sentence for each paragraph. You want to clearly state the main idea of that paragraph in the very first sentence. From there, you back up that main idea with facts and reputable sources. Make sure your topic sentence is clear, but does not just announce your topic. 

For example, do not write something like: “In this paragraph, I will discuss why it’s bad that poachers are killing giraffes.”

Instead, write something that clearly states your idea with a reasonable opinion and that gives direction to the paragraph: “Giraffes are a key part of the African ecosystem, so it’s important to enforce regulations against the poachers who are killing them for their body parts.” 

You’d then follow that up with reasons why giraffes are a key part of the African ecosystem and how poachers are destroying their population.

Step 4: Begin writing your essay.

Once you have your thesis statement and you’ve created an outline with supporting paragraphs and their topic sentences, you can begin writing your essay. It’s important to make that outline before just jumping in–a disorganized essay can spell disaster for you as you continue to write, and could result in a poor grade. Many times, teachers will even require you to turn in your outline as part of your overall essay grade. 

Step 5: Proofread and check your resources.

After you’ve written the essay, go back through it with a fine tooth comb. Read through each topic sentence and the paragraphs that follow to ensure that you’ve written clear, solid topic sentences throughout and that the paragraphs with them make sense. During the proofreading phase, you also need to recheck the sources you’re using. Make sure each source is reputable. In other words, do not use sites like Wikipedia where anyone can go in and edit an article to add misinformation. Use sites that:

• Are actual reputable news sources, such as the New York Times , CNN, CBS News
• Have domain names that end in .edu or .gov
• Come from an encyclopedia, such as Encyclopedia Britannica

Using sites that are not reputable could jeopardize the validity of your argument.

Now that you know the steps to set yourself up for success when writing a topic sentence, there are certain elements that go into a quality first sentence. Always make sure that your topic sentence is the first sentence of a paragraph. You don’t want to make your reader hunt for the point you’re trying to make. Check out some key elements of a good topic sentence:

Make sure your topic sentence isn’t too vague.

You need a topic sentence that has some specifics to it. It also needs to hook in your reader in some way with an opinion. A vague sentence makes it harder to write a paragraph that can clearly backs up your thoughts. For example:

DON’T: “In Pride and Prejudice, Mr. Bingley seems like a nice guy.”

DO: “When Mr. Bingley is first introduced, he comes across as a kind person because he speaks to everyone and doesn’t immediately pass judgment.”

Choose a reasonable opinion.

Your topic sentence should clearly outline whatever point you’re trying to make in the paragraph, but you want to pick a reasonable opinion that you can easily reinforce with facts and statistics. Here’s an example of what you should and should not do:

DON’T: “It’s obvious that Mr. Bingley was a total loser with no backbone.”

DO: “Mr. Bingley could have shown more confidence in his choices and stood up to Mr. Darcy when he found himself in love with Jane Bennet.”

You can then back that up with facts, saying that he was a wealthy Englishman and thus one of the key players in society at the time, which should have given him more confidence. If he’d been more confident, perhaps he would not have left and devastated Jane.

Use your topic sentence as a transition.

Along with telling the reader the point of your next paragraph, your topic sentence should also serve as a transition from the previous paragraph. Without a transition, the essay can feel like it’s choppy and disjointed. For example:

DON’T: “Mr. Bingley is a good man and here’s why.”

DO: “Although Mr. Bingley did break Jane’s heart by leaving, he ended up redeeming himself by returning to Netherfield Hall.”

Keep your topic sentence short.

A long, drawn-out topic sentence can risk losing your reader. Many times, it’s hard to determine the point of a sentence when it goes on for too long. You want a clear, concise sentence that draws in the reader but also leaves some room for you to expand on it in the following paragraph.

DON’T: “Throughout the novel of Pride and Prejudice, Mr. Bingley was often quite different from Mr. Darcy as he would treat all people in a friendly manner, considering them all his friends and acquaintances, even agreeing to throw a ball after Elizabeth’s sisters rudely demanded he do so and was gracious to Mr. and Mrs. Bennet as well despite their manners.”

DO: “Overall, Mr. Bingley served as a foil to Mr. Darcy throughout the story by treating everyone around him equally with dignity and grace.”

Writing an essay can be overwhelming at times, but so long as you avoid some of these common pitfalls, it can be easier to get it done on time. 

Don’t wait until the last minute.

If your teacher assigns you an essay or tells you that you have an essay test coming up, don’t wait until the day before to do anything about it. You have to plan or study and you need to give yourself time to do that. If you know it takes you a while to write something, then start planning it as soon as you get the assignment.

Don’t forget to write an outline.

Along with planning, make sure you have that outline written up and planned out well. It will serve as your guideline for writing the essay. Without it, you’ll face the risk of a disorganized essay that does not clearly illustrate your point.

Ask for help if you need it.

This may be the most important pitfall to avoid. If you get in over your head while writing, don’t be afraid to ask for help. Ask a friend to review the essay or ask your teacher for guidance.

What is a Topic Sentence? (Definition, Examples, How to Use)

What is a topic sentence ? A topic sentence , the first sentence of a paragraph, presents the main concept discussed in the paragraph. It must contain sufficient information to support numerous examples and subtopics without being too broad to obscure the essay’s intended purpose. The remaining sentences in the paragraph will act as supporting statements, providing evidence and examples for the main idea.

Importance of topic sentences

In essays or articles , where subjects can shift from one paragraph to another, a topic phrase is particularly crucial. The topic sentences, superficially, may seem to serve the purpose of only acting like the initial or introductory sentence of a paragraph. But it has numerous other purposes that make it an important part of essays.

• Topic sentences link paragraphs together to improve the sentence flow and make reading easier. When topic sentences are not used, switching between paragraphs can feel abrupt and jarring to the reader. Authors can maintain the rhythm of their writing using topic sentences and facilitate smooth transitions.
• Topic sentences show the reader a sample of what to expect from the paragraph. The readers can determine from the topic sentence whether the paragraph will comprise a narrative, a list, anecdotal evidence, statistical data, persuasive opinions, or some other form of evidence.
• If two conflicting viewpoints are presented in a single paragraph, authors can use more than one topic sentence to inform the readers about the changes in the main concept. For example, paragraphs that “compare and contrast” require more than one topic sentence. In these kinds of paragraphs, authors can start with a topic sentence introducing the first idea and follow it up with proof or evidence supporting the idea. Then they can introduce the second topic sentence conveying the opposing viewpoint, followed by proof or evidence supporting it.

Different types of topic sentences

The different types of topic sentences include:

Simple statement

This topic sentence is used by authors to make a general observation or statement and then elaborate on it in the body of the paragraph.

New studies are emerging indicating the link between climate change and the emergence of numerous new virus strains.

Interrogative or question

This is used by writers in less formal settings. Authors can start a paragraph using implicit or explicit questions related to the topic of discussion to engage the readers.

How many nations are ready to adapt to rising sea levels?

Complex topic sentences are used when the author is discussing a complicated concept that encompasses multiple ideas. Such topic sentences cover more than a single core idea.

Although many people believe that a mother bird will reject its chick if it is touched by humans, the truth is that birds do not abandon their babies after humans touch them.

Authors can use their topic sentences to make explicit demands or pleas to their readers. This will be helpful in breaking the monotony of the essay.

Let’s look at the data from the latest research.

Purely transitional

Though topic sentences are generally responsible for facilitating a smooth transition between paragraphs, occasionally they are purely transitional. These function best when the main topic shifts abruptly by highlighting the switch.

But not everybody agrees.

Pivot sentences are not found at the beginning of a paragraph but rather in the middle, indicating a change in the topic. Conjunctive adverbs like however, furthermore, and meanwhile are frequently used with them.

However, the undisputed king of tennis, Roger Federer, was dethroned in 2008 at Wimbledon.

How to create good topic sentences

A good topic sentence can be created using some simple steps:

1. Determine the key point of your essay

Writers should first form an understanding of the topic of the essay and then create topic sentences to attract the attention of readers. Constructing a good thesis statement can assist the writer in forming better topic sentences.

2. Have an outline for the essay

The author should form a plan or roadmap beforehand on the topics they want to discuss in a paragraph and the evidence they want to use as supporting statements.

3. Be coherent and clear

Writers should make their topic sentences clear and comprehensible so that the reader can form a clear understanding of what to expect in the paragraph.

4. Share opinions

It is advisable to share the opinion or viewpoint of the author in the topic sentence to attract the attention of the reader. Authors should also refrain from writing obvious facts in the topic sentences.

5. Use specific wordings

The topic sentences ought to be precise enough so that the authors can use a few sentences in the paragraph to support them.

6. Transitions should be added between paragraphs

To give the essay or paper a throughline, authors can create topic sentences that refer to the prior paragraph. A topic sentence can make a reference to the preceding paragraph while introducing the next part by using transitional words.

7. Use new, relevant information

Instead of using an obvious fact that everybody knows as the topic sentence, authors can give new information. It is also important to present them in an interesting way.

8. Create a compound or complex topic statement

Compound or complex topic statements feel advanced and stronger. Authors can create such topic statements to add a high level of sophistication to their text.

Many beginner writers and students confuse thesis statements with topic sentences. In essence, thesis statements establish the major idea discussed in the entire essay or paper, as opposed to topic sentences, which introduce the central concept of a paragraph.

Both of these sentences are responsible for giving the readers a sample of what to expect, but in entirely different capacities. Suppose a person is writing a thesis about the different compounds present in coffee and the health benefits it offers.

The thesis statement will be a generalized statement indicating that there are numerous compounds in coffee that benefit the health of humans. But the topic sentence of each paragraph will introduce any single health benefit or compound present in the coffee.

Topic sentences are typically found at the beginning of a paragraph. But this does not mean that they cannot be placed elsewhere in the paragraph. In some cases, when the details discussed can be summarized into a general statement, topic sentences can be included at the end.

Similarly, in some paragraphs where multiple concepts are discussed, topic sentences may be used in the middle of the paragraph. The placement depends on the number of topics being discussed and the way they are discussed.

Writing Topic Sentences — Purpose, Structure, and Examples

What is a topic sentence?

A topic sentence in academic writing identifies how a body paragraph relates to the overall purpose of an essay stated in the thesis statement . Topic sentences are usually at the beginning of a paragraph and identify the paragraph’s controlling idea.

While an essay’s thesis statement identifies the point of the essay in its entirety, the topic sentence has a much narrower focus, as it relates only to the paragraph in which it is located.

What is the purpose of a topic sentence?

The purpose of a topic sentence is to inform the reader of the main idea of the paragraph and how it connects to the overall objective of the essay. An effective topic sentence accomplishes one or more of the following:

Makes a claim

Supports other claims made in the paper

Identifies the purpose of the rest of the paragraph

Relates the paragraph to the purpose of the paper

Precedes information that defends a claim

How to write a topic sentence

To write a topic sentence, incorporate the following guidelines:

Determine the thesis of the essay.

Identify the main supports that help prove the thesis.

Use each main support to structure a topic sentence for each paragraph.

Compose a sentence that answers the following questions:

What will the paragraph prove?

How does the paragraph connect to the thesis?

Where is the topic sentence in a paragraph?

Topic sentences can be placed at the beginning or end of a paragraph.

Although it does not need to be the first sentence, the topic sentence should be placed at the beginning of the paragraph so the reader can quickly identify the purpose of the paragraph.

While not a common placement for a topic sentence, some writers use topic sentences at the end of a paragraph. Writers who choose this method want the reader to deduce the main point of the paragraph by presenting the evidence first.

Topic sentence examples

The following list identifies topic sentences based on the provided thesis statements for five-paragraph essays:

Thesis Statement: Capital punishment should be banned because it is inhumane, unconstitutional, and ineffective at deterring crime.

Support Paragraph 1 Topic Sentence: The inhumane nature of the death penalty proves it should be abolished.

Support Paragraph 2 Topic Sentence: Capital punishment should be outlawed because it violates the Constitution.

Support Paragraph 3 Topic Sentence: Because the death penalty does not effectively deter criminal behavior, states should not continue to use it.

Thesis Statement: College athletes should be financially compensated because they sacrifice their minds and bodies, cannot hold an outside job, and increase the school’s revenue.

Support Paragraph 1 Topic Sentence: Student athletes should be paid for their performance because of sports’ impact on their minds and bodies.

Support Paragraph 2 Topic Sentence: Because most college athletes cannot play their sport and hold a job, colleges should give them a living wage.

Support Paragraph 3 Topic Sentence: Student-athletes’ ability to increase their college’s revenue proves they should be awarded financial compensation.

Thesis Statement: Using alternative energy sources can help lessen the impact of global climate change.

Support Paragraph 1 Topic Sentence: Through the widespread use of solar power, countries can limit the environmental impact of other energy sources.

Support Paragraph 2 Topic Sentence: Utilizing more wind turbines as a power source can help mitigate the effects of climate change.

Support Paragraph 3 Topic Sentence: Using geothermal power will effectively decrease the world's reliance on fossil fuels.

Types of Topic Sentences

There are several different types of topic sentences that can be used in writing to introduce the reader through a paragraph or essay.

Simple Statement Topic Sentence This is the most common type of topic sentence, which straightforwardly states the main point or idea of the paragraph or essay.

Example: The rise of social media has revolutionized the way people communicate with each other.

Complex Topic Sentence This type of topic sentence is more nuanced and may require some explanation or elaboration to fully understand.

Example: While the rise of social media has had many positive effects on communication, it has also led to concerns about privacy and online harassment.

Pivot Topic Sentence A pivot topic sentence begins by connecting the current paragraph or idea to the previous one, before pivoting to introduce a new point or idea.

Example: Building on the idea of social media's impact on communication, it is important to consider how it has also affected business and marketing strategies.

Question Topic Sentence A question topic sentence poses a question that the rest of the paragraph or essay will answer or explore.

Example: How has social media changed the way businesses interact with customers and advertise their products?

Command Topic Sentence This type of topic sentence gives a directive or instruction, often used in persuasive or argumentative essays.

Example: Support local businesses by shopping at independently owned stores instead of large chains.

How to Write a Topic Sentence?

Here are a few instructions to help you write a good topic sentence. 

Step#1 Clearly State The Main Idea

A topic sentence is the first paragraph of the paragraph. It must clearly explain the particular subject that would be discussed in the paragraph. This should be stated in very clear language so that the reader can easily understand the idea. 

Also, it should include a bit of your personal opinion and also the main idea. 

Step#2 Hook Your Reader

Grab your reader's attention with an intriguing topic sentence. It would excite and make the reader curious about the content and convince them to read the particular part. 

Look out for some amazing hook examples and see what fits your essay type. 

Use a meaningful and relevant question or a fact as a topic sentence of the paragraph. Make sure that you have identified your audience and are developing everything accordingly. 

Step#3 Keep It Short and Precise

The paragraph topic sentence must be expressive enough that a reader understands your point of view effortlessly. This is only possible if you keep everything to the point, short, and meaningful. 

Choose the words in such a way that they help you express your idea in an ideal way. Avoid using complex sentences and use independent clauses.  

A topic sentence acts as a link between a paragraph and the main thesis statement. It should be specific and connected to the overall essay. Keeping it short and precise helps maintain the paragraph's flow and its relevance to the rest of the writing.

Step#4 Give A Reasonable Opinion

The body paragraph explains a topic sentence. This is why it is important that you should write this sentence in such a way that it can be explained in the paragraph.  If you are mentioning a fact in the topic statement, make sure that you have authentic evidence to support it. 

While the topic sentence is an integral part of the paragraph, it should stand out and possess a distinctiveness that sets it apart from the other sentences. This can be achieved by employing transition words and establishing connections between sentences.

Step#5 Use The Topic Sentence As A Transition

The topic sentences that serve as transition sentences can be considered a guide for the readers. This way, they can help the reader to move through the essay in a flow. 

Write this sentence in such a way that it creates a gateway between the previous paragraph and the rest of the essay. Moreover, it will also help keep the essay organized, and the reader understands the point of a paragraph.

Step#6 Look For Some Good Examples

Examples can help you learn a thing in a better way. If you are new to writing topic sentences, it can help to look at some examples. Find some great examples of topic sentences relevant to your essay topic.

Difference Between Topic Sentence and Thesis Sentence

Here's a table outlining the differences between a topic sentence and a thesis statement:

Good Topic Sentence Examples

Here are ten examples of good topic sentences:

•  "Despite the advancements in technology, traditional forms of communication are still essential in today's society."
• "The theme of power is prevalent throughout Shakespeare's play, Macbeth."
• "In recent years, there has been a growing concern over the impact of climate change on our planet."
• "The legalization of marijuana has been a topic of debate for many years." "Education is the key to success in life."
• "The rise of social media has greatly impacted the way we communicate with one another."
• "The effects of childhood trauma can have a lasting impact on mental health."
• "The concept of justice is explored in depth in Harper Lee's To Kill a Mockingbird."
• "Eating a balanced diet is crucial for maintaining good health."
• "The Industrial Revolution had a profound effect on the world as we know it today."

The Bottom Line!

An opening sentence is crucial to grab your reader's attention and set the tone for your piece of writing. The topic sentence introduces the controlling idea and acts as an important sentence in the essay outline. 

Effective topic sentences are necessary for a well-structured and organized essay. It's an integral part of the writing process that should not be overlooked.

What is a topic sentence?

A topic sentence states the main point of a paragraph: it serves as a mini-thesis for the paragraph. You might think of it as a signpost for your readers—or a headline—something that alerts them to the most important, interpretive points in your essay. When read in sequence, your essay’s topic sentences will provide a sketch of the essay’s argument. Thus topics sentences help protect your readers from confusion by guiding them through the argument. But topic sentences can also help you to improve your essay by making it easier for you to recognize gaps or weaknesses in your argument.

Where do topic sentences go?

Topic sentences usually appear at the very beginning of paragraphs. In the following example from Anatomy of Criticism , Northrop Frye establishes the figure of the tragic hero as someone more than human, but less than divine. He backs up his claim with examples of characters from literature, religion and mythology whose tragic stature is a function of their ability to mediate between their fellow human beings and a power that transcends the merely human:

The tragic hero is typically on top of the wheel of fortune, half-way between human society on the ground and the something greater in the sky. Prometheus, Adam, and Christ hang between heaven and earth, between a world of paradisal freedom and a world of bondage. Tragic heroes are so much the highest points in their human landscape that they seem the inevitable conductors of the power about them, great trees more likely to be struck by lightning than a clump of grass. Conductors may of course be instruments as well as victims of the divine lightning: Milton’s Samson destroys the Philistine temple with himself, and Hamlet nearly exterminates the Danish court in his own fall.

The structure of Frye’s paragraph is simple yet powerful: the topic sentence makes an abstract point, and the rest of the paragraph elaborates on that point using concrete examples as evidence.

Does a topic sentence have to be at the beginning of a paragraph?

No, though this is usually the most logical place for it. Sometimes a transitional sentence or two will come before a topic sentence:

We found in comedy that the term bomolochos or buffoon need not be restricted to farce, but could be extended to cover comic characters who are primarily entertainers, with the function of increasing or focusing the comic mood. The corresponding contrasting type is the suppliant, the character, often female, who presents a picture of unmitigated helplessness and destitution. Such a figure is pathetic, and pathos, though it seems a gentler and more relaxed mood than tragedy, is even more terrifying. Its basis is the exclusion of an individual from the group; hence it attacks the deepest fear in ourselves that we possess—a fear much deeper than the relatively cosy and sociable bogey of hell. In the suppliant pity and terror are brought to the highest possible pitch of intensity, and the awful consequences of rejecting the suppliant for all concerned is a central theme of Greek tragedy.

The context for this passage is an extended discussion of the characteristics of tragedy. In this paragraph, Frye begins by drawing a parallel between the figure of the buffoon in comedy and that of the suppliant in tragedy. His discussion of the buffoon occurred in a earlier section of the chapter, a section devoted to comedy. The first sentence of the current paragraph is transitional: it prepares the way for the topic sentence. The delayed topic sentence contributes to the coherence of Frye’s discussion by drawing an explicit connection between key ideas in the book. In essays, the connection is usually between the last paragraph and the current one.

Sometimes writers save a topic sentence for the end of a paragraph. You may, for example, occasionally find that giving away your point at the beginning of a paragraph does not allow you to build your argument toward an effective climax.

How do I come up with a topic sentence? And what makes a good one?

Ask yourself what’s going on in your paragraph. Why have you chosen to include the information you have? Why is the paragraph important in the context of your argument? What point are you trying to make?

Relating your topic sentences to your thesis can help strengthen the coherence of your essay. If you include a thesis statement in your introduction, then think of incorporating a keyword from that statement into the topic sentence. But you need not be overly explicit when you echo the thesis statement. Better to be subtle rather than heavy-handed. Do not forget that your topic sentence should do more than just establish a connection between your paragraph and your thesis. Use a topic sentence to show how your paragraph contributes to the development of your argument by moving it that one extra step forward. If your topic sentence merely restates your thesis, then either your paragraph is redundant or your topic sentence needs to be reformulated. If several of your topic sentences restate your thesis, even if they do so in different words, then your essay is probably repetitive.

Does every paragraph need one?

No, but most do. Sometimes a paragraph helps to develop the same point as in the previous paragraph, and so a new topic sentence would be redundant. And sometimes the evidence in your paragraph makes your point so effectively that your topic sentence can remain implicit. But if you are in doubt, it’s best to use one.

Paragraphs & topic sentences.

A paragraph is a series of sentences that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. This is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus help the reader see the organization of the essay and grasp its main points.

Paragraphs can contain many different kinds of information. A paragraph could contain a series of brief examples or a single long illustration of a general point. It might describe a place, character, or process; narrate a series of events; compare or contrast two or more things; classify items into categories; or describe causes and effects. Regardless of the kind of information they contain, all paragraphs share certain characteristics. One of the most important of these is a topic sentence.

TOPIC SENTENCES

A well-organized paragraph supports or develops a single controlling idea, which is expressed in a sentence called the topic sentence. A topic sentence has several important functions: it substantiates or supports an essay’s thesis statement; it unifies the content of a paragraph and directs the order of the sentences; and it advises the reader of the subject to be discussed and how the paragraph will discuss it. Readers generally look to the first few sentences in a paragraph to determine the subject and perspective of the paragraph. That’s why it’s often best to put the topic sentence at the very beginning of the paragraph. In some cases, however, it’s more effective to place another sentence before the topic sentence—for example, a sentence linking the current paragraph to the previous one, or one providing background information.

Although most paragraphs should have a topic sentence, there are a few situations when a paragraph might not need a topic sentence. For example, you might be able to omit a topic sentence in a paragraph that narrates a series of events, if a paragraph continues developing an idea that you introduced (with a topic sentence) in the previous paragraph, or if all the sentences and details in a paragraph clearly refer—perhaps indirectly—to a main point. The vast majority of your paragraphs, however, should have a topic sentence.

PARAGRAPH STRUCTURE

Most paragraphs in an essay have a three-part structure—introduction, body, and conclusion. You can see this structure in paragraphs whether they are narrating, describing, comparing, contrasting, or analyzing information. Each part of the paragraph plays an important role in communicating your meaning to your reader.

Introduction : the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.

Body : follows the introduction; discusses the controlling idea, using facts, arguments, analysis, examples, and other information.

Conclusion : the final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea.

The following paragraph illustrates this pattern of organization. In this paragraph the topic sentence and concluding sentence (CAPITALIZED) both help the reader keep the paragraph’s main point in mind.

SCIENTISTS HAVE LEARNED TO SUPPLEMENT THE SENSE OF SIGHT IN NUMEROUS WAYS. In front of the tiny pupil of the eye they put , on Mount Palomar, a great monocle 200 inches in diameter, and with it see 2000 times farther into the depths of space. Or they look through a small pair of lenses arranged as a microscope into a drop of water or blood, and magnify by as much as 2000 diameters the living creatures there, many of which are among man’s most dangerous enemies. Or , if we want to see distant happenings on earth, they use some of the previously wasted electromagnetic waves to carry television images which they re-create as light by whipping tiny crystals on a screen with electrons in a vacuum. Or they can bring happenings of long ago and far away as colored motion pictures, by arranging silver atoms and color-absorbing molecules to force light waves into the patterns of original reality. Or if we want to see into the center of a steel casting or the chest of an injured child, they send the information on a beam of penetrating short-wave X rays, and then convert it back into images we can see on a screen or photograph. THUS ALMOST EVERY TYPE OF ELECTROMAGNETIC RADIATION YET DISCOVERED HAS BEEN USED TO EXTEND OUR SENSE OF SIGHT IN SOME WAY. George Harrison, “Faith and the Scientist”

In a coherent paragraph, each sentence relates clearly to the topic sentence or controlling idea, but there is more to coherence than this. If a paragraph is coherent, each sentence flows smoothly into the next without obvious shifts or jumps. A coherent paragraph also highlights the ties between old information and new information to make the structure of ideas or arguments clear to the reader.

Along with the smooth flow of sentences, a paragraph’s coherence may also be related to its length. If you have written a very long paragraph, one that fills a double-spaced typed page, for example, you should check it carefully to see if it should start a new paragraph where the original paragraph wanders from its controlling idea. On the other hand, if a paragraph is very short (only one or two sentences, perhaps), you may need to develop its controlling idea more thoroughly, or combine it with another paragraph.

A number of other techniques that you can use to establish coherence in paragraphs are described below.

Repeat key words or phrases. Particularly in paragraphs in which you define or identify an important idea or theory, be consistent in how you refer to it. This consistency and repetition will bind the paragraph together and help your reader understand your definition or description.

Create parallel structures. Parallel structures are created by constructing two or more phrases or sentences that have the same grammatical structure and use the same parts of speech. By creating parallel structures you make your sentences clearer and easier to read. In addition, repeating a pattern in a series of consecutive sentences helps your reader see the connections between ideas. In the paragraph above about scientists and the sense of sight, several sentences in the body of the paragraph have been constructed in a parallel way. The parallel structures (which have been emphasized ) help the reader see that the paragraph is organized as a set of examples of a general statement.

Be consistent in point of view, verb tense, and number. Consistency in point of view, verb tense, and number is a subtle but important aspect of coherence. If you shift from the more personal "you" to the impersonal “one,” from past to present tense, or from “a man” to “they,” for example, you make your paragraph less coherent. Such inconsistencies can also confuse your reader and make your argument more difficult to follow.

Use transition words or phrases between sentences and between paragraphs. Transitional expressions emphasize the relationships between ideas, so they help readers follow your train of thought or see connections that they might otherwise miss or misunderstand. The following paragraph shows how carefully chosen transitions (CAPITALIZED) lead the reader smoothly from the introduction to the conclusion of the paragraph.

I don’t wish to deny that the flattened, minuscule head of the large-bodied "stegosaurus" houses little brain from our subjective, top-heavy perspective, BUT I do wish to assert that we should not expect more of the beast. FIRST OF ALL, large animals have relatively smaller brains than related, small animals. The correlation of brain size with body size among kindred animals (all reptiles, all mammals, FOR EXAMPLE) is remarkably regular. AS we move from small to large animals, from mice to elephants or small lizards to Komodo dragons, brain size increases, BUT not so fast as body size. IN OTHER WORDS, bodies grow faster than brains, AND large animals have low ratios of brain weight to body weight. IN FACT, brains grow only about two-thirds as fast as bodies. SINCE we have no reason to believe that large animals are consistently stupider than their smaller relatives, we must conclude that large animals require relatively less brain to do as well as smaller animals. IF we do not recognize this relationship, we are likely to underestimate the mental power of very large animals, dinosaurs in particular. Stephen Jay Gould, “Were Dinosaurs Dumb?”

Paragraphs: Topic Sentences

Topic sentences video playlist.

• Academic Paragraphs: Introduction to Paragraphs and the MEAL Plan (video transcript)
• Academic Paragraphs: Examples of the MEAL Plan (video transcript)

The best way to understand the role of the topic sentence in paragraph development is to imagine that any given paragraph is a miniature essay that has its own thesis, support, and conclusion. The parts of a paragraph easily correspond to the parts of an essay:

Just as an effective essay starts off with an introduction that presents the paper's thesis statement and indicates the specific claim or argument that the essay will develop, each paragraph should begin with a topic sentence that indicates the focus of that paragraph, alerting the reader to the particular subtopic that the paragraph will provide evidence to support.

A strong topic sentence should be placed at or near the beginning of a paragraph. In addition, this sentence should focus on a specific issue, avoid the use of direct quotations, and leave room for support and analysis within the body of the paragraph. Read on to learn more about creating an effective topic sentence.

The topic sentence does not have to be the first sentence in the paragraph; however, it should come early in the paragraph in order to orient the reader to the paragraph's focus right away. Occasionally a writer may place a transition sentence before the topic sentence, to create continuity between topics.

Topic Sentence to begin paragraph:

In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

Transition Sentence + Topic Sentence to begin paragraph:

However, Morrison does not only use the emotional and spiritual bonds between her female characters to initiate their coming-of-age. In addition, the author uses the physical bonds of female friendship to propel her adolescent protagonists into self-awareness.

Specificity

Your topic sentence should be more narrowly focused than your thesis sentence, and you will want to make sure the claim you are making can be supported, argued, and analyzed within the body of your paragraph.

Example: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

In this topic sentence, the essayist is arguing that physical bonds of friendship, specifically, make the female characters more self-aware. Because this idea can be refuted or supported by readers (based on how successfully the essayist persuades his or her readers with examples and analysis from the novel), and because the claim is narrow enough to address within a single paragraph, the above sentence is a successful topic sentence.

Direct Quotations (Are Best Avoided)

Although it might be tempting to begin a paragraph with a compelling quotation, as a general rule, topic sentences should state the main idea of the paragraph in your own words. Direct quotations have a place later in the paragraph, where they may be incorporated to support the topic sentence.

Needs Improvement: As Morrison (1982) conveyed, the girls' "friendship let them use each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

Better: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness. Pointing to the connection of eyes meeting and bodies growing together, Morrison makes coming-of-age an interactive physical process between the adolescent protagonists. Specifically, Morrison describes how Sula and Nel have used "each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

In this second paragraph, the topic sentence appears first, immediately orienting readers to the main focus (or topic) of the paragraph. The quotation is used later in the paragraph as a form of evidence or support for the topic sentence.

If you are finding it challenging to create effective topic sentences, you might consider outlining before beginning to write a paper. The points and subpoints of an outline can then become the topic sentences for the paper's paragraphs.

Additionally, because the topic sentence functions similarly at the paragraph level to the thesis at the essay level, you may also find it helpful to check out our thesis statement construction information. Our resource on paragraphs has helpful information about the scope of a paragraph, as well.

How to Write a Good Topic Sentence

Last Updated: March 7, 2024 Fact Checked

She earned her PhD in English from the University of Georgia in 2015. There are 10 references cited in this article, which can be found at the bottom of the page.

Perfecting the skill of writing topic sentences is essential to successful writing. A topic sentence usually comes at the beginning of a paragraph and lets your reader know what to expect from each paragraph. Think of it as the preview for a movie or a headline in a newspaper, highlighting the “main point” that’s to come in that paragraph. [1] X Research source Make sure your topic sentences are up to par, and the rest of your writing will feel like a breeze.

Writing a Successful Topic Sentence

• Keep in mind that this is not an invitation to simply announce your topic. “Today I’m going to discuss the benefits of gardening” is not an effective topic sentence. You should be able to make your intentions clear without stating them explicitly.
• The topic sentence in this example states a clear direction (“health benefits of gardening”) that you can then elaborate on in your paragraph.

• Don’t write too vague or general an idea or you will never be able to discuss it in a single paragraph. This is too general: “The United States suffered a lot during the Civil War.”
• Don’t write too narrow of a statement. There’s nothing much to talk about then, because it’s probably a fact. This is too narrow: “Christmas trees are either cedars or firs."
• Instead, aim for a good balance: “Sherman’s destruction in the South during the Civil War also caused incredible suffering.” This is big enough to relate to the broader idea of an essay, but not so narrow that there’s nothing left to discuss.

• Describe a character. This can be a physical or emotional description.
• Use dialogue. If there is a relevant conversation that will attract your reader’s attention, consider using part of it to start your paragraph.
• Portray an emotion. Use the opening sentence to portray an emotion to your reader.
• Use detail. While you don’t want to write a run on sentence by creating too much detail, it’s a good idea to create interest using sensory language in your topic sentence.
• Avoid rhetorical questions. While you want your reader to formulate questions in his or her mind, you do not want to formulate the questions yourself.

• Avoid presenting only facts in your topic sentence. While facts may be interesting, they do not introduce the reader to your paragraph nor do they draw the reader in. If you wish to include a fact, also include your own input. For example, instead of writing “All dogs need food,” try “All dogs need regular care, including healthy food, and children are the best ones to do it.” Alternatively, save your facts to use as evidence in the body of your paragraph.

• Using transitional elements, such as “In addition” or “In contrast,” is a good way to show the relationship between your ideas.
• For example: “Although gardening has many health benefits, people still need to exercise caution when outside.” This topic sentence establishes a connection to the main idea of the previous paragraph (“health benefits of gardening”) and points to the direction of the new paragraph (“things to be cautious of”).

Planning Your Topic Sentences

• You don’t have to write a formal outline using Roman numerals and the like. Even a loose, idea-based outline can help you know what you want to discuss.

• A topic sentence, unlike a thesis statement, doesn’t have to present an argument. It can present a “preview” of what the paragraph will argue or discuss.

• For example, a topic sentence could look like this: “In addition, increasing funding for public roads in Jackson County will improve local residents’ quality of life.” The rest of the sentences in this paragraph would relate to the main idea of public roads and how they will help benefit local residents.
• This is not as successful a topic sentence: “Increased funding for public roads in Jackson County has decreased traffic by 20%.” While this is probably an interesting fact for your argument, it’s too narrow for a topic sentence. The topic sentence has to direct the whole paragraph.

Avoiding Common Problems

• Unless it is an opinion piece, avoid using ‘I’ in your topic sentences.

• Rather than stating something like “In the story, Amelia did many good things such as help out her friends, talk to her parents, and support her team at school” say something like “As a result of the many activities Amelia participated in, she was recognized for her positive influence on the community.”

Sample Topic Sentences

Community Q&A

• Avoid using words like you or we because it implies you know the reader, which you don’t. Thanks Helpful 0 Not Helpful 0
• In formal writing, avoid contractions such as “don’t,” “can’t,” and “isn’t.” Also avoid other common contractions like “would’ve” and “could’ve” which are commonly used. Instead type them out to look like “do not,” “can not”, “is not”, “would have”, and “could have.” Thanks Helpful 0 Not Helpful 0

About This Article

If you’re trying to write a good topic sentence, start by clearly stating your main idea, which should include the topic and the position you’re taking on it. Aim to write a sentence that’s broad enough for discussion but narrow enough to be covered in a single paragraph. If you can, start with a hook, like a detail, character, or emotion that would draw in your readers.

What Is a Topic Sentence?

• An Introduction to Punctuation
• Ph.D., Rhetoric and English, University of Georgia
• M.A., Modern English and American Literature, University of Leicester
• B.A., English, State University of New York

A topic sentence is a  sentence , sometimes at the beginning of a paragraph , that states or suggests the main idea (or topic ) of a paragraph.

Not all paragraphs begin with topic sentences. In some, the topic sentence appears in the middle or at the end. In others, the topic sentence is implied or absent altogether.

Examples and Observations

• " Salva and the other boys made cows out of clay. The more cows you made, the richer you were. But they had to be fine, healthy animals. It took time to make a lump of clay look like a good cow. The boys would challenge each other to see who could make the most and best cows." (Linda Sue Park, A Long Walk to Water . Clarion, 2010)
• " Momma bought two bolts of cloth each year for winter and summer clothes. She made my school dresses, underslips, bloomers, handkerchiefs, Bailey's shirts, shorts, her aprons, house dresses and waists from the rolls shipped to Stamps by Sears and Roebuck. . . ." (Maya Angelou, I Know Why the Caged Bird Sings . Random House, 1969)
• " You discover what it is like to be hungry. With bread and margarine in your belly, you go out and look into the shop windows. Everywhere there is food insulting you in huge, wasteful piles; whole dead pigs, baskets of hot loaves, great yellow blocks of butter, strings of sausages, mountains of potatoes, vast Gruyère cheeses like grindstones. A snivelling self-pity comes over you at the sight of so much food. You plan to grab a loaf and run, swallowing it before they catch you; and you refrain, from pure funk." (George Orwell, Down and Out in Paris and London . Victor Gollancz, 1933)
• " The flavor that salt imparts to food is just one of the attributes that manufacturers rely on. For them, salt is nothing less than a miracle worker in processed foods. It makes sugar taste sweeter. It adds crunch to crackers and frozen waffles. It delays spoilage so that the products can sit longer on the shelf. And, just as importantly, it masks the otherwise bitter or dull taste that hounds so many processed foods before salt is added." (Michael Moss, Salt, Sugar, Fat: How the Food Giants Hooked Us . Random House, 2013)
• " The very idea of retirement is a relatively new invention. For most of human history, people worked until they died or were too infirm to lift a finger (at which point they died pretty fast anyway). It was the German statesman Otto von Bismarck who first floated the concept, in 1883, when he proposed that his unemployed countrymen over the age of 65 be given a pension. This move was designed to fend off Marxist agitation—and to do so on the cheap, since few Germans survived to that ripe old age." (Jessica Bruder, "The End of Retirement." Harper's , August 2014)
• " Grandma's room I regarded as a dark den of primitive rites and practices. On Friday evenings whoever was home gathered at her door while she lit her Sabbath candles. . . ."  (E.L. Doctorow, World's Fair . Random House, 1985)
• " Genealogy is an ancient human preoccupation. The God of Hebrew Scripture promised Abraham descendants beyond number, like the stars in the sky and the sand on the seashore. The apostles Matthew and Luke claim that Abraham's lineage went on to include King David and eventually Jesus, though the specifics of their accounts are contradictory. Muslims trace Mohammed's line back through Abraham, to Adam and Eve." (Maud Newton, "America's Ancestry Craze." Harper's , June 2014)
• " O nce, in a restaurant in Italy with my family, I occasioned enormous merriment, as a nineteenth-century humorist would have put it, by confusing two Italian words. I thought I had, very suavely, ordered for dessert fragoline —those lovely little wild strawberries. Instead, I seem to have asked for fagiolini —green beans. The waiter ceremoniously brought me a plate of green beans with my coffee, along with the flan and the gelato for the kids. The significant insight the mistake provided—arriving mere microseconds after the laughter of those kids, who for some reason still bring up the occasion, often—was about the arbitrary nature of language: the single 'r' rolled right makes one a master of the trattoria, an 'r' unrolled the family fool. . . ." (Adam Gopnik, "Word Magic." The New Yorker , May 26, 2014)
• " In seventeenth-century Europe, the transformation of man into soldier took on a new form, more concerted and disciplined, and far less pleasant, than wine. New recruits and even seasoned veterans were endlessly drilled, hour after hour, until each man began to feel himself part of a single, giant fighting machine. . . ." (Barbara Ehrenreich, Blood Rites: Origins and History of the Passions of War . Henry Holt and Company, 1997)
• " What is the appeal of train travel? Ask almost any foamer, and he or she will invariably answer, 'The romance of it!' But just what this means, they cannot really say. It's tempting to think that we are simply equating romance with pleasure, with the superior comfort of a train, especially seated up high in the observation cars. . . ." (Kevin Baker, "21st Century Limited: The Lost Glory of America's Railroads." Harper's , July 2014)
• " Because science fiction spans the spectrum from the plausible to the fanciful, its relationship with science has been both nurturing and contentious. For every author who meticulously examines the latest developments in physics or computing, there are other authors who invent 'impossible' technology to serve as a plot device (like Le Guin’s faster-than-light communicator, the ansible) or to enable social commentary, the way H. G. Wells uses his time machine to take the reader to the far future to witness the calamitous destiny of the human race." (Eileen Gunn, "Brave New Words." Smithsonian , May 2014)
• " I passed all the other courses that I took at my university, but I could never pass botany. . . ." (James Thurber, My Life and Hard Times . Harper & Row, 1933)
• " What is there about this wonderful woman? From next door, she comes striding, down the lawn, beneath the clothesline, laden with cookies she has just baked, or with baby togs she no longer needs, and one's heart goes out. Pops out. The clothesline, the rusted swing set, the limbs of the dying elm, the lilacs past bloom are lit up like rods of neon by her casual washday energy and cheer, a cheer one has done nothing to infuse." (John Updike, "One's Neighbor's Wife." Hugging the Shore: Essays and Criticism . Knopf, 1983)
• " Television. Why do I watch it? The parade of politicians every evening: I have only to see the heavy, blank faces so familiar since childhood to feel gloom and nausea. . . ." (J.M. Coetzee, Age of Iron . Random House, 1990)
• " Anyone who has made the coast-to-coast journey across America, whether by train or by car, has probably passed through Garden City, but it is reasonable to assume that few travelers remember the event. It seems just another fair-sized town in the middle--almost the exact middle--of the continental United States. . . ." (Truman Capote, In Cold Blood . Random House, 1966)
• " Rodeo, like baseball, is an American sport and has been around almost as long. . . ." (Gretel Ehrlich, The Solace of Open Spaces . Viking Penguin, 1985)
• " What a piece of work is a book! I am not talking about writing or printing. I am talking about the codex we may leaf through, that may be put away on a shelf for whole centuries and will remain there, unchanged and handy. . . ." (William Golding, A Moving Target . Farrar, Straus and Giroux, 1982)

Characteristics of an Effective Topic Sentence

• "A good topic sentence is concise and emphatic . It is no longer than the idea requires, and it stresses the important word or phrase. Here, for instance, is the topic sentence which opens a paragraph about the collapse of the stock market in 1929: "The Bull Market was dead."(Frederick Lewis Allen) Notice several things. (1) Allen's sentence is brief . Not all topics can be explained in six words, but whether they take six or sixty, they should be phrased in no more words than are absolutely necessary. (2) The sentence is clear and strong: you understand exactly what Allen means. (3) It places the keyword—'dead'—at the end, where it gets heavy stress and leads naturally into what will follow. . . . (4) The sentence stands first in the paragraph. This is where topic sentences generally belong: at or near the beginning." (Thomas S. Kane, The New Oxford Guide to Writing . Oxford Univ. Press, 1988)

Positioning a Topic Sentence

"If you want readers to see your point immediately, open with the topic sentence . This strategy can be particularly useful in letters of application or in argumentative writing. . . . "When specific details lead up to a generalization, putting the topic sentence at the end of the paragraph makes sense. . . . "Occasionally a paragraph's main idea is so obvious that it does not need to be stated explicitly in a topic sentence." (Andrea Lunsford, The St. Martin's Handbook . Bedford/St. Martin's, 2008)

Guidelines for Composing Topic Sentences

"The topic sentence is the most important sentence in your paragraph. Carefully worded and restricted, it helps you generate and control your information. An effective topic sentence also helps readers grasp your main idea quickly. As you draft your paragraphs, pay close attention to the following three guidelines:

• Make sure you provide a topic sentence. . . .
• Put your topic sentence first.
• Be sure your topic sentence is focused. If restricted, a topic sentence discusses only one central idea. A broad or unrestricted topic sentence leads to a shaky, incomplete paragraph for two reasons:
• The paragraph will not contain enough information to support the topic sentence .
• A broad topic sentence will not summarize or forecast specific information in the paragraph."

(Philip C. Kolin, Successful Writing at Work , 9th ed. Wadsworth, 2010)

Testing for Topic Sentences

"When testing your article for topic sentences , you should be able to look at each paragraph and say what the topic sentence is. Having said it, look at all the other sentences in the paragraph and test them to make sure they support it. . . .

"If you find that you have come up with the same topic sentence more than once, you have two paragraphs doing the same work. Cut one of them out.

"If you find a paragraph that has several sentences that don't support the topic sentence, see if all the outlaw sentences support some other topic sentence and turn the one paragraph into two." (Gary Provost, "How to Test Your Articles for the 8 Essentials of Nonfiction." Handbook of Magazine Article Writing , ed. by Jean M. Fredette. Writer's Digest Books, 1988)

Frequency of Topic Sentences

"Teachers and textbook writers should exercise caution in making statements about the frequency with which contemporary professional writers use simple or even explicit topic sentences in expository paragraphs. It is abundantly clear that students should not be told that professional writers usually begin their paragraphs with topic sentences."  (Richard Braddock, "The Frequency and Placement of Topic Sentences in Expository Prose." Research in the Teaching of English . Winter 1974)

Topic Sentences

Characteristics of a strong topic sentence.

The topic sentence functions two ways: it clearly refers to and supports the essay’s thesis, and it indicates what will follow in the rest of the paragraph. As the unifying sentence for the paragraph, it is the most general sentence, whereas all supporting sentences provide different types of more specific information, such as facts, details, or examples. An effective topic sentence has the following characteristics:

• A topic sentence has a topic and an angle, extracted from the thesis sentence.

Thesis : Although working for the national parks service may be considered by some to be a “summer job,” careers with the national parks offer mobility within the profession, support for continued learning, and satisfaction in knowing that you are contributing to the preservation and health of the country’s resources.

Weak example #1 : National Parks in the U.S. were created in 1916 under President Woodrow Wilson and currently offer hundreds of summer job opportunities per year.

Explanation : This sentence sticks with the topic, national parks, but does not offer an angle extracted from the ideas in the thesis. An essay should not have topic sentences and units of support that are not planned for in the thesis.

Stronger example : Workers with the national parks are encouraged and, in many cases, required to maintain current knowledge within their fields, which is offered through on-the-job training, attendance at seminars, and tuition assistance for appropriate college courses.

Explanation : Choose any part of the angle in the thesis to create a topic sentence with its own topic and angle.

Weak example #2 : National Parks work has provided me with many benefits.

Explanation : Although the thesis itself deals with benefits, a topic sentence derived from that thesis needs to more carefully extract a specific portion of that that thesis and make a point about that specific portion.

• A topic sentence provides an accurate indication of what will follow in the rest of the paragraph.

Weak example : First, we need a better way to educate students.

Explanation : The claim is vague because it does not provide enough information about what will follow, and it is too broad to be covered effectively in one paragraph or short unit of support.

Stronger example : Creating a national set of standards for math and English education will improve student learning in many states.

Explanation : The sentence replaces the vague phrase “a better way” and leads readers to expect supporting facts and examples as to why standardizing education in these subjects might improve student learning in many states.

• A good topic sentence is the most general sentence in the paragraph and thus does not include supporting details.

Weak example : Salaries should be capped in baseball for many reasons, most importantly so we don’t allow the same team to win year after year.

Explanation : This topic sentence includes a supporting detail that should be included later in the paragraph to back up the main point.

Stronger example : Introducing a salary cap would improve the game of baseball for many reasons.

Explanation : This topic sentence omits the additional supporting detail so that it can be expanded upon later in the paragraph, yet the sentence still makes a claim about salary caps – improvement of the game.

• A good topic sentence is clear and easy to follow.

Weak example : In general, writing an essay, thesis, or other academic or nonacademic document is considerably easier and of much higher quality if you first construct an outline, of which there are many different types.

Explanation : The confusing sentence structure and unnecessary vocabulary bury the main idea, making it difficult for the reader to follow the topic sentence.

Stronger example : Most forms of writing can be improved by first creating an outline.

Explanation : This topic sentence cuts out unnecessary verbiage and simplifies the previous statement, making it easier for the reader to follow. The writer can include examples of what kinds of writing can benefit from outlining in the supporting sentences.

TOPIC SENTENCE/ In his numerous writings, Marx critiques capitalism by identifying its flaws. ANALYSIS OF EVIDENCE/ By critiquing the political economy and capitalism, Marx implores his reader to think critically about their position in society and restores awareness in the proletariat class. EVIDENCE/ To Marx, capitalism is a system characterized by the “exploitation of the many by the few,” in which workers accept the exploitation of their labor and receive only harm of “alienation,” rather than true benefits ( MER 487). He writes that “labour produces for the rich wonderful things – but for the worker it produces privation. It produces palaces—but for the worker, hovels. It produces beauty—but for the worker, deformity” (MER 73). Marx argues capitalism is a system in which the laborer is repeatedly harmed and estranged from himself, his labor, and other people, while the owner of his labor – the capitalist – receives the benefits ( MER 74). And while industry progresses, the worker “sinks deeper and deeper below the conditions of existence of his own class” ( MER 483).  ANALYSIS OF EVIDENCE/ But while Marx critiques the political economy, he does not explicitly say “capitalism is wrong.” Rather, his close examination of the system makes its flaws obvious. Only once the working class realizes the flaws of the system, Marx believes, will they - must they - rise up against their bourgeois masters and achieve the necessary and inevitable communist revolution.

Not every paragraph will be structured exactly like this one, of course. But as you draft your own paragraphs, look for all three of these elements: topic sentence, evidence, and analysis.

• picture_as_pdf Anatomy Of a Body Paragraph

• Literary Terms

Topic Sentence

I. what is a topic sentence.

A topic sentence in a paragraph is like the GPS in a car. It shows you (and others) where you are going and explains the point of the paragraph. Everything else is used as supporting details. The topic sentence contains two parts: the topic and a controlling idea. The topic is WHAT the paragraph is going to be about, and the controlling idea explains WHY the paragraph is being written. The topic sentence helps your reader understand the purpose of your paragraph.

II. Examples of a Topic Sentence

The purpose of your paragraph will be made clear in your topic sentence. The most common reasons for writing are to persuade, to inform, and to entertain. It is also possible that a sentence could do more than one of these.

You will often use a persuasive topic sentence when writing for school, such as in literary essays .

The character Pip in the novel Great Expectations learns the importance of loyalty through his        interactions with the convict Abel Magwitch.

An informative topic sentence is often found in scientific articles.

White blood cells help fight infections by attacking bacteria, viruses and germs that invade the         body.

Topic sentences that entertain are sometimes found in magazines or other less formal writing.

It’s not hard to raise a bad child if you follow these simple instructions.

III. Parts of a Topic Sentence

There are just two parts in a topic sentence, the topic and the controlling idea. The topic is WHAT the paragraph is about, and the controlling idea explains WHY you are writing the paragraph. In the examples below, the topic is in orange and the controlling idea is in green .

Joseph loves to spend time with his friends .

What/who is this paragraph about? Joseph. Why is this paragraph being written? To explain something that Joseph loves to do.

Disneyland is the happiest place on Earth .

What/who is this paragraph about? Disneyland. Why is it being written? To show why Disneyland is the happiest place on Earth.

IV. Placement of Topic Sentences

A. initial placement.

The most common place for a topic sentence is at the beginning of the paragraph because it explains what the paragraph is going to discuss. The initial placement helps the writer organize the paragraph and tells the reader what to expect right in the beginning.

The best things in life are free . Although most people work hard to buy a good home or a nice car, those are not the things that they care about the most. At the end of their lives, they don’t want to hug their cars, or the walls of their fine houses. They want to be surrounded by the people they care about and who care about them. Kindness is free. Love is free. Friendship is free (or at least it should be!). Of course it is important to make money to survive, but love is important to live happily.

b. Final Placement

Sometimes the topic sentence is at the end of the paragraph, especially when the paragraph is a narrative or a mysterious story. Placing it at the end creates suspense or sometimes works to tell the point of the story.

The wealthy man was dying. He called for his friends and family to be near him and placed a hand on each one’s shoulder. They cried because they would miss him, and he cried because he had no more time to share with them. The beautiful things that he’d purchased over the years held no meaning. He didn’t care about his diamonds or his yacht or his large home. He cared for his children and the love they shared. They were here with him now and held his hands. He was glad he’d learned the most important lesson in life: the best things in life are free .

c. Medial Placement

The last place, the least common place for a topic sentence, is in the middle of the paragraph. The medial topic sentence usually functions as a transition between two ideas or details.  This works when you want to show that there are two (sometimes opposite) points to an issue, but the one you are arguing, the second point, is stronger, more specific, or more important. This topic sentence is generally introduced with a transition signal.

You can’t survive on love alone. People need money for basic necessities: food, shelter and clothing. Without money, life would be uncomfortable and difficult. However, time and energy should not be completely spent on making money because the best things in life are free . Having fun with friends and family is more important and more satisfying than buying a new car or nice clothes. People provide warmth, affection, understanding, and most of all, love. Money can’t love you back, and it does not guarantee happiness. Some of the richest people in the world are miserable, while some of the poorest people in the world are happy because they have the simple joy of loving people in their lives.  

V. How to Write a Topic Sentence

A. the best way to write your topic sentence is to consider why you are writing the paragraph.

• Decide on your reason for writing the paragraph
• After you have figured that out, write down the important details you want to include and see what they all have in common.
• Summarize the details into one sentence.

For example, if you want to write about your favorite movie, think about all the reasons that you like it. Is it funny? Exciting? Dramatic? Romantic? Be sure not to include too many things or else you will end up with an essay instead of a simple sentence. Once you have decided on your details, you are ready to write the topic sentence.

Here’s an example, the topic will be in orange and the controlling idea will be in green :

The best movie ever made was “Star Wars: the Force Awakens” because it was exciting and surprising .

An important point to remember is that the topic sentence should contain all relevant information that’s going to be in the paragraph. There should be no information about romance or comedy. It should only talk about what made the movie exciting.

b. Mistakes to Avoid

One of the biggest problems students face is keeping a paragraph or essay on topic. Sometimes they will write a good topic sentence but halfway through the paragraph, they think of another good idea and follow that. Without revision and editing, the topic sentence will not serve its purpose in the paragraph.

The best vacation I ever had was in Hawaii. The beaches were so beautiful and clean that swimming in them was like a dream . I especially loved the Waikiki beach. At night, there were free shows with dancers and live music. The music was so good that it made me want to dance. Dancing is my favorite thing to do in the world. When I was young, I studied ballet and tap dance. I’m thinking about taking it back up again. I might even study hip-hop!

The paragraph started out with Hawaii and end up with hip-hop dancing. You can see how the writer’s train of thought began to wander in the seventh sentence. With a different topic sentence, it would be possible to save this paragraph. Consider how different the direction would be with the following topic sentence.

The best vacation I ever had was in Hawaii. I especially loved the Waikiki beach. At night, there were free shows with dancers and live music. The music was so good that it made me want to dance and reminded me that dancing is my favorite activity in the world. In fact, when I was young, I studied ballet and tap dance. The dancing that I saw in Hawaii inspired me to get back into dancing . I might even study hip-hop!

With this new topic sentence, the second sentence would have to be eliminated or changed a bit. You can see how easy it is to get off-topic, but with a good topic sentence, and constant reference back to it, you are less likely to have that problem.

VI. So remember

• A topic sentence needs to contain the topic of your paragraph and a controlling idea.
• Everything in the paragraph should be connected to the topic sentence.
• The placement of the topic sentence depends on the type of paragraph.

VII. Exercises

Each of the paragraphs in this exercise has three possible topic sentences following it. Choose the best one and make sure that it includes the main idea of the paragraph.

1. _____________________________________________. In fact, he usually shows up five minutes early everywhere he goes. Because he’s so considerate, he hates to keep people waiting. He also believes that being early creates a better expereince. One time, when we were going to a movie together, John arrived thirty minutes earlier just so he could get the best seats in the theatre. I’m glad to have such a punctual friend.

a. John loves going to the movies.

b. John is always on time.

c. John hates to be kept waiting.

2. _________________________________________. The place is never crowded, but the service is still terrible. It seems like the staff has better things to do than wait on customers. Once I waited ten minutes just to buy a slice of pizza, and I was the only person in the whole store! I recommend staying away from Billy Bob’s Pizzeria.

a. Billy Bob’s Pizzeria has the worst pizza.

b. Billy Bob’s Pizzeria is an unpopular place to eat.

c. Billy Bob’s Pizzeria has terrible customer service.

3. I walked slowly down the dark path, afraid of my own shadow. But the tug on the leash propelled me forward. Buck, my golden retriever, was determined to take the most deserted trails through the forest. I could hear unfamiliar noises on all sides and urged Buck to do his business quickly. Oh, why couldn’t he be toilet trained? That would be better for everyone! _____________________________________.

a. Buck is an inconsiderate dog.

b. I hate walking my dog at night.

c. The forest is a dangerous place to walk at night.

4. Generally speaking, zoos these days are losing popularity. Many people feel that it’s unfair to lock up wild animals to entertain humans. ________________________________ . Some zoos go to great lengths to build a good environment for its animals. The good zoos treat their animals well and provide opportunities for the public to learn about the natural world. The best zoos protect endangered species and raise awareness about animals and their habitats.

a. Zoos perform a valuable service to society and should be part of every person’s childhood memory.

b. Zoos are horrible places that should be shut down because it’s not humane to lock up wild animals.

c. Zoos that do their best to make a pleasant habitat for the animals can be a pleasant place to visit.

Topic Sentence and Paragraph Organization

Paragraph organization refers to the way sentences are structured and ordered to create a unified and cohesive body of text.

The principal features to consider in paragraph organization are the topic sentence and controlling idea, supporting details, organizational patterns, and signal words. Together, these features develop a topic and connect ideas from one point to the next, logically and fluidly. This resource explains these features and provides numerous examples of paragraph organization.

The Topic Sentence and Controlling Idea

Similar to a thesis statement, which establishes the central focus or point of a whole piece of writing, a topic sentence works at the paragraph level to express the focus and general point of an individual paragraph. A topic sentence has two parts: 1) the topic that is being discussed throughout the paragraph and 2) a controlling idea that limits the focus on the topic to one point or idea. Each additional sentence in the paragraph then develops or expounds on that point with supporting details. The example topic sentence below is from a body paragraph in an informative essay.

Example Topic Sentence and Controlling Idea

The economy also plays a role in an increase in prescription pain reliever addiction.

The example topic sentence suggests the paragraph topic is “the economy,” and the controlling idea about the economy is how it “plays a role in an increase” in opioid addition. The signal word “also” connects this topic as an additional example or contributing factor to the opioid epidemic, the focus of the paper. The example below shows the topic sentence in the context of the complete paragraph.

The economy also plays a role in an increase in prescription pain reliever addiction. According to Jungeun Olivia Lee, a social work professor at University of Southern California, “The relationship between joblessness and substance abuse is strongest among people from low socioeconomic brackets, who might not be able to afford healthier ways to relieve their stress” (2017, as cited in Khazan, 2017, para. 8). Additionally, every point the unemployment rate rises, opioid-related death rates rise by almost 4 percent (Khazan, 2017). Unemployment makes it not only difficult for those suffering from pain to afford medication or healthy alternatives, but it can also contribute to depression and varying degrees of self-medication and addiction.

Supporting Details

In a paragraph, the topic and controlling idea are developed with supporting details. Listed here are some types of supporting details found in paragraphs along with an example of each in a sentence.

Facts: statistics or evidence from research that can be verified

• The office sold seven million dollars of real estate during the boom years.

Opinions: statements, quotes, or paraphrases from subject matter experts

• According to expert tea maker, Millie Stoff, there are three easy steps to making tea.

Definitions: explanations of what a term or concept means

• A crossover is a family vehicle with the features of a sedan, a mini-van, and an SUV.

Examples: parts, pieces, instances, traits, or specimens that illustrate the essence or character of a greater whole.

• Mario is a shy, introverted young man. For example, he has few friends and mostly keeps to himself.

Anecdotes: narrative accounts of one time or recurring events

• When I visited the Washington Monument, I enjoyed the 180-degree view the most.

Descriptions: a visual or sensory depiction of a person, place, event, activity, or idea

• Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees.

Example Paragraph and Analysis of the Supporting Details

Hiking can be exhilarating during snowy winter months. When my friend and I visited North Carolina last January, we hiked in the Blue Ridge Mountains near the highest peak, Mount Mitchell, which is6,684 feet above sea level. We first crossed a foot bridge over a rapidly moving, ice-cold river and then followed a wooded trail up to a waterfall. Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees. We saw deer and rabbits as we trekked up the path. I assure you that nothing feels better than inhaling crisp mountain air, but the neatest part of hiking in winter, besides the beauty of the mountain, is exhaling and seeing my breath turn to frost when it hits the cold air!

The topic sentence in the example paragraph indicates that the paragraph is on “hiking,” and the focus is that hiking is “exhilarating” during winter. The sentences in the paragraph support and develop this idea with an anecdote of the writer’s experience hiking up a mountain during winter. An anecdote is a narrative account that helps a reader understand an event or situation. Had the writer said hiking was “dangerous” instead of “exhilarating,” the anecdote in addition to the visual and sensory details, facts, and opinions about the experience would have been different. Additionally, while the sample paragraph is a personal account, writers in many professions use anecdotal evidence to report events from an objective point-of-view, where the writer is not a participant but rather a witness or observer.

Paragraph Organization

Along with having topic sentences and supporting details, paragraphs are also organized to achieve a certain purpose. However, just as a paragraph can contain different types of supporting details, a paragraph may also include more than one organizational pattern. Listed here are some common patterns for organizing a paragraph:

• Cause and Effect for showing how one thing leads to another
• Chronological Order for narrating events that occurred over time
• Classification for grouping things together according to their features
• Comparison and Contrast for showing how things are similar or different
• Definition and Example for defining a term or idea and then expanding it with examples
• Description for listing details
• Episode for presenting details or information about a specific event or anecdote
• General/Specific Order for presenting a general idea followed by specific examples
• Generalization/Principle for making a general statement or applying a broad principle to explain the supporting details
• Listing for presenting ideas from least to most important
• Order of Importance for building up to or leading away from the most important point.
• Problem and Solution for presenting an issue and a way to address it
• Process/Cause for explaining what or how something happens and then why
• Spatial Order for ordering details directionally

Signal Words

Signal words are signposts or clues to a paragraph’s organization. If the word “type” is used in a sentence, for example, it signals that the ideas involve types or classification, which is an organizational pattern. Signal words are context clues that hint at what the paragraph is about and how it is organized.

Listed here are signal words associated with different types of paragraph organization.

• Cause and Effect : because, consequently, for this reason, hence, and on account of
• Chronological Order : after, at last, at (time), as long as, at the same time, as soon as, before, during, eventually, finally, in (month or year), later, meanwhile, next, on (day or date), since, second, subsequently, then, until, and whenever
• Classification : categories, classes, classifications, elements, features, groups, kinds, methods, types, varieties, and ways
• Comparison and Contrast : another, both, however, likewise, one difference, on the other hand, on the contrary, similarity, similarly, unlike, and while
• Definition and Example : concept, defined as, described as, e.g., for example, for instance, i.e., illustrates, is, is called, is stated, known as, means, refers to, specifically, such as, term, and that is to say
• Description : above, across, along, appears to be, as in, behind, below, beside, between, down, in back of, in front of, looks like, near, onto, on top of, outside, over, such as, to the right/left, and under
• Episode : a few days/weeks later, around the same time, as a result of, as it is often called, because of, began when, consequently, for this reason, just, lasted for, led to, shortly thereafter, since then, subsequently, this led to, and when
• General/Specific Order : for example, for instance, indeed, in fact, in other words, like, namely, such as, and that is
• Generalization/Principle : additionally, always, because of, clearly, conclusively, first, for instance, for example, furthermore, generally, however, if…then, in fact, it could be argued that, moreover, most convincing, never, not only…but also, often, second, therefore, third, truly, and typically
• Listing : additionally, also, and, as well as, besides, furthermore, in addition, in fact, moreover, or, plus, and too
• Order of Importance : central, chief, ending with, finishing with, key, lastly, least, main, major, finally, primary, principal, and significant
• Problem and Solution : answer, challenge, difficulty, dilemma, enigma, indicate, improve, issue, need, plan, problem, propose, resolve, respond, solve, and suggest

• Spatial Order : above, below, behind, beside, down, east, feels, highest, looks, lowest, next to, north, smells, sounds, south, tastes, under, and west

Sample Paragraphs and Analyses of the Organization

The sample paragraphs in this section illustrate topic sentences, supporting details, organizational patterns, and signal words in context. Read each paragraph to identify the type of paragraph organization on your own, and then proceed to the analysis to check your comprehension.

Sample Paragraph 1

• In 1995, Lawrence started his real estate business, and it has since become a huge success. When Lawrence Real Estate opened its door in Oviedo, Florida, it sold seven million dollars of real estate during the first few boom years. By 2000, Lawrence decided to open two branch offices: one in Tampa in 2003 and one in Miami in 2004. By 2007, the home office and both the branch offices had survived the economic slowdown, so Lawrence and his associates expanded their business to the Carolinas and opened a branch office in Charlotte in 2020. It can be safely said that Lawrence Real Estate has become a model for success despite economic struggles and real estate devaluation.

Analysis of Paragraph 1: According to the topic sentence, which contains two coordinating clauses and therefore two subjects and two topics, this paragraph is about Lawrence and his real estate business, and the controlling idea is that they have been successful.

To understand how the supporting details are organized to present information about this topic and idea, the reader can consider the supporting details. To do this, they look at the way the sentences begin and at any signal phrases that lead readers along a certain line of thinking. Here are some key signal words: “in 1995,” “By 2000,” “By 2007,” and “in 2020.” These dates make a pattern. They go back to 1995 and then in a chronological order, they move forward to when the success of the business happened.

This paragraph uses chronological order . The reader will notice too that the last sentence returns to the beginning idea of 15 years ago. In this sentence, a final comment about the time period overall is given with respect to the new information

Sample Paragraph 2

• Making a great cup of tea is easy if you follow these three steps. First, heat a cup of water to the boiling point. Then put the tea bag in the hot water, and let it steep for at least three minutes. Finally, add creamer and sugar to taste. There is nothing tastier than a strong cup of tea early in the morning.

According to the topic sentence, which is the first sentence of the paragraph, making a cup of tea is the topic, and the controlling idea is that it’s easy to do if you follow three steps. Signal words open the following sentences: “first,” “then,” and “finally.” These indicate a sequence of steps, not times or dates as in a narrative story, but steps that happen in a specific order as in the process of doing something or informing others how to do something.

This paragraph uses process order (or process/cause). In the last sentence of this paragraph, the process is completed with a return to the original topic—a cup of tea—and a new comment about it—that a strong cup is tasty in the morning, making those three steps not only easy but also worthwhile.

Sample Paragraph 3

• The Washington Monument is divided into three main areas. The lowest section of the building houses the entrance, a gift shop, and a restaurant. The middle section consists of elevators and stairways to the top. The top section of the monument includes an observation deck with a spectacular view of the Washington D.C. area. When I visited the Washington Monument, I toured every section but enjoyed the spectacular 180-degree view the most.

Based on the topic sentence at the beginning of the paragraph, the topic is the Washington Monument, and the controlling idea is that it is divided into three main areas. The paragraph presents information about the lowest section first, the middle section second, and the top section third. The last sentence makes a remark about the most enjoyable of all the sections. This is an example of spatial organization . The information is given in the order you might see it if you were there.

Sample Paragraph 4

• There are three types of family vehicles made in the United States. The first type is the minivan. All American car manufacturers make a version of the minivan. Some say that the comfort and amenities of the minivan compare to none. The second type of family vehicle is the SUV. Some SUVs offer four-wheel-drive to navigate tough terrains, and they also offer seating for a large crowd. A third type of family vehicles is called the crossover. These vehicles supposedly have the best features of the sedan, minivan, and SUV. They are easy to maneuver, look much like a regular sedan, and sit up to six people. All of these vehicles are family friendly; they offer safety, roomy comfort, and many extra features to accommodate the special needs of families.

This paragraph shows another way to organize the details of a topic. The topic sentence of this paragraph is structured differently than the previous ones. Typically, the topic of a sentence is also the grammatical subject, but the subject in this sentence is “there,” a pronoun, and the topic that tells what the paragraph is about, “family vehicles,” is in the predicate of the sentence. The controlling idea is that there are three types made in the U.S.

The paragraph is organized according to those three types: the first type, the second type, and the third type. To conclude, there is a comment about “all of these vehicles” or all of these types of vehicles. When information is organized by types or features, the information is classified. This type of organization is classification .

Sample Paragraph 5

• Although the twin brothers share many physical characteristics, they handle themselves differently in social situations. Mario is a shy introverted young man. He has few friends and mostly keeps to himself. On the other hand, Gino is outgoing and the life of the party. Unlike Mario, Gino has many friends and feels totally at ease among big crowds. The best way to tell these identical twins apart is to invite both to a party and observe how differently they interact with the other guests.

When the topic sentence is complex (having more than one clause) as in this paragraph, there may be two subjects and therefore two topics; however, here, the subject of the first clause is “the twin brothers” and the subject for the second clause is “they,” so both subjects refer to the same topic—the twin brothers. The controlling idea is that the twin brothers share many physical characteristics but handle themselves differently socially.

The paragraph then progresses with descriptions of these similarities and differences. Contrast is created by signal phrases and words such as “although, “on the other hand,” and “unlike.” Words such as “apart” and “differently” also indicate that the organizational pattern of this paragraph is comparison and contrast .

Sample Paragraph 6

• There are many reasons why I enjoy walking tours when visiting new cities. For starters, walking through a city allows the visitor to see the details of an area without having to hurry. This often results in meeting locals and experiencing their lives and traditions first hand. Furthermore, walking tours are flexible and inexpensive because there are no strict schedules or transportation expenses. Travelers taking walking tours are rewarded with firsthand experiences in the places they visit and the opportunity to personally interact with the people who live there.

Because the first sentence begins with “there are,” the reader must move beyond the subject and verb to find the topic. Additionally, this is a complex sentence with an independent and dependent clause connected by “why,” so there may be two topics. Looking at the objects of both clauses, the reader finds “many reasons” and “walking tours.” These two topics are linked together by the controlling idea: the writer enjoys walking tours while visiting new cities for many different reasons.

The signal words build on this idea of “why” with terms such as “results” and “because.” The last sentence then sums up the ultimate effect of walking tours: Travelers are rewarded. This is an example of cause and effect organization.

Sample Paragraph 7

• Hiking can be especially exhilarating during snowy winter months. When my friend and I visited North Carolina last January, we hiked in the Blue Ridge Mountains near the highest peak, Mount Mitchell, which is 6,684 feet above sea level. We first crossed a footbridge over a rapidly moving, ice-cold river and then followed a wooded trail up to a waterfall. Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees. We saw deer and rabbits as we trekked up the path. I assure you that nothing feels better than inhaling crisp mountain air, but the neatest part of hiking in winter, besides the beauty of the mountain, is exhaling and seeing my breath turn to frost when it hits the cold air!

In the first sentence, the topic of the paragraph is “hiking,” and the comment or main idea is that it “can be especially exhilarating during snowy winter months.” Based on this, the reader can expect supporting details to illustrate this exhilaration, but they do not know how it is organized until they look at the signal words that help progress the topic from one idea to the next.

Taking inventory of the signal words, the reader will find several time markers: “When” and “last January” set the narrative in the past while “first” and “then” develop a chronological order of events. The final summarizing sentence about hiking “in winter” reminds the reader of the season.

Within this chronology , signal words are associated with spatial organization: “over,” “up,” “beneath,” “through,” “crunched” (sounded), “saw,” “feels,” and “seeing.” Narratives typically include descriptive elements about the setting. Additionally, the concluding thought contrasts “inhaling” to “exhaling.” The reader can thus conclude that this paragraph has multiple patterns of organization that are intricately connected.

Do your essays and papers lack clarity and cohesion? Are your readers often left wondering what point you're trying to make?

You're not alone!

Many writers struggle with this issue, and it often stems from the absence of a strong foundation in their essay writing : the topic sentence.

In this ultimate guide, we will define what a topic sentence is, provide you with clear examples, and offer valuable tips to help you write effective topic sentences.

Let’s get started.

• 1. What is a Topic Sentence In An Essay? 
• 2. Elements of a Good Topic Sentence

What is a Topic Sentence In An Essay? 

In an essay, a topic sentence is the first sentence in a paragraph, and it gives us a sneak peek into what the paragraph will talk about. 

It's like a signpost that helps the reader know what's coming up next.

Each topic sentence in a paragraph must have a topic and a controlling idea to show where the information is heading. 

What is the Purpose of a Topic Sentence?

The purpose of a topic sentence is to make your writing clear and organized. Think of it like this: if you're telling a story, you wouldn't jump from one topic to another without letting your friends know, right? That would be confusing!

Similarly, in writing, a topic sentence helps your reader know what to expect in each paragraph. It's like a mini-map for your essay. 

When you read the topic sentence, you instantly get a sense of what the paragraph will discuss.

Here's why topic sentences are important:

• Guides the Reader : It helps the reader understand what each paragraph is about. It's like a helpful signpost along the reading journey.
• Keep Your Writing Organized: Just like you wouldn't mix up ingredients when cooking, a topic sentence keeps your ideas in order. It makes sure each paragraph has a clear focus.
• Connects Your Ideas : Topic sentences connect one paragraph to the next. They create a smooth flow in your essay, like linking train cars together.
• Helps You Stay on Track : As a writer, a topic sentence helps you stay on topic. It reminds you of what you wanted to say in that paragraph.

Where Is The Topic Sentence Placed?

The placement of a topic sentence in a paragraph is crucial for conveying the main idea and guiding the reader's understanding. 

Typically, the topic sentence is positioned at the beginning of a paragraph. This serves as a clear and concise statement that introduces the central theme or point that the rest of the paragraph will discuss and support. 

Elements of a Good Topic Sentence

A good topic sentence possesses several key elements that distinguish it as an effective component of your writing:

• Clarity : It should be clear and straightforward, leaving no room for ambiguity or confusion about the paragraph's main point.
• Specificity : A strong topic sentence is precise and specific, focusing on a single aspect of the broader topic to maintain a clear direction.
• Relevance : It must be directly related to the thesis statement or overall purpose of your writing, ensuring that it contributes to the central argument.
• Conciseness : It should be concise and to the point, avoiding unnecessary wordiness and getting straight to the heart of the matter.
• Connection : A good topic sentence should establish a clear link to the previous paragraph or the essay's overarching theme, creating a seamless flow of ideas.

Although most of the essay paragraphs must have a topic sentence. But there are some cases when there is no need to add it at all. For example, you can omit if the paragraph continues to develop a story or idea that you introduced in the previous paragraph.

How to Write a Topic Sentence - 5 Simple Steps

Writing an effective topic sentence is a skill that can significantly improve your writing. Follow these five precise steps to craft a compelling topic sentence:

Identify the Main Idea

Be specific and concise, connect to the thesis, check for unity, engage the reader.

Let's break down each of the five steps for writing a topic sentence in more detail:

Before writing your topic sentence, take a moment to identify the main idea of the paragraph. What specific point of view or information in the paragraph do you want to convey?

This is the crux of your paragraph and should be crystal clear in your mind before you start writing.

Once you've identified the main idea, express it in a specific and concise manner. Avoid general statements that lack depth or detail.

Specificity adds clarity to your writing and helps readers understand precisely what you're discussing.

Your topic sentence should align with the thesis statement of your essay or the overall purpose of your document.

This connection ensures that every paragraph contributes directly to your central argument or message. It also keeps your writing coherent and focused.

Ensure that your topic sentence serves as the glue that holds the paragraph together. All the supporting sentences in the paragraph should relate to and reinforce the main idea presented in the topic sentence.

This unity creates a logical and cohesive flow within your writing.

Consider your topic sentence as the hook that captures the reader's attention. Craft it in a way that intrigues the reader and entices them to continue reading.

This engagement is crucial, as it sets the tone for the entire paragraph and encourages readers to invest their time in your content.

Topic Sentences Examples 

Here are five examples of topic sentences, along with their respective topics and controlling ideas:

• Topic: Climate change
• Controlling Idea: Growing threat to global ecosystems
• Topic: Time management skills
• Controlling Idea: academic success
• Topic: Benefits of regular exercise
• Controlling Idea: Extend beyond physical health
• Topic: Artificial intelligence
• Controlling Idea: reshaping the job market
• Topic: Digital marketing strategies
• Controlling Idea: Transforming business audience reach

Common Pitfalls in Crafting Topic Sentences

When writing a topic sentence, it's important to be aware of common pitfalls and things to avoid to ensure its effectiveness in your writing. 

Here are key things to steer clear of:

• Vagueness and Ambiguity

Avoid using vague or ambiguous language in your topic sentence. A topic sentence should clearly convey the main idea of the paragraph without leaving readers guessing.

• Overly Broad Statements

Steer clear of making sweeping, overly broad statements in your topic sentence. Keep it focused on a specific aspect of the topic to maintain clarity.

• Lack of Connection

Ensure your topic sentence connects logically to the previous paragraph or the overall theme of your essay. Avoid abrupt transitions that disrupt the flow of your writing.

Avoid restating the thesis or repeating information from the essay introduction in your topic sentence. Instead, use it to introduce new ideas or aspects of your argument.

Topic sentences introducing complex sentences or information that may confuse readers. Keep it concise and straightforward. 

In conclusion, writing effective topic sentences is a skill that can significantly elevate your writing. 

By following the steps outlined in this guide, you can ensure that your topic sentences are clear, concise, and engaging.

Remember to identify the main idea, connect to your central argument, engage your readers from the very beginning. Avoid common pitfalls like vagueness, repetition, and lack of relevance, as discussed earlier.

Some good topic sentence starters include:

• Additionally
• Furthermore
• In contrast
• On the other hand
