How to Write a Topic Sentence (30+ Tips & Examples)

Writing the perfect topic sentence took me years to master.

After endless drafts, feedback sessions, and seeing what resonates with readers, I’ve distilled the ultimate guide to craft attention-grabbing, informative, and concise topic sentences.

Let’s dive into the essential tips for how to write a topic sentence.

What Is a Topic Sentence and Why Is It Important?

Table of Contents

A topic sentence introduces the main idea, usually appearing at the start of a paragraph.

It sets the tone for the entire paragraph by giving a glimpse of what’s coming. Think of it as a headline for each paragraph that keeps your writing clear and focused.

A strong topic sentence is important because:

• Grabs Attention: Captures the reader’s interest, encouraging them to keep reading.
• Guides Structure: Helps organize thoughts in a logical way.
• Provides Focus: Prevents rambling by clarifying the main point.

Types of Topic Sentences

Different types of topic sentences can fit various writing styles and purposes.

Understanding these types will help you select the best approach for your specific content.

• Declarative Statements: These are straightforward sentences that make a clear assertion. They introduce the main idea without any fluff or ambiguity. Example: “Water conservation is critical in regions prone to drought.”
• Interrogative Sentences: These topic sentences pose a question, encouraging readers to think critically and seek answers within the paragraph. Example: “How can sustainable practices help reduce waste in the fashion industry?”
• Complex Sentences: By combining independent and dependent clauses, these topic sentences present a nuanced main idea that prepares readers for a more detailed discussion. Example: “Although renewable energy sources are gaining popularity, fossil fuels still dominate the global energy sector.”
• Bridge Sentences: These link the preceding paragraph to the next, providing continuity and coherence in the overall structure. Example: “While electric vehicles offer a greener alternative to traditional cars, the infrastructure for widespread adoption remains lacking.”
• Contrasting Statements: These topic sentences highlight opposing viewpoints or circumstances, building intrigue and depth into the following paragraph. Example: “Despite the technological advancements in healthcare, access remains limited for underserved communities.”

My 30 Best Tips for Writing a Topic Sentence

Now let’s get into the main section of this guide — where you will learn all the best tips for writing a compelling topic sentence on any subject.

Tip #1: State the Main Idea Clearly

Make sure your topic sentence introduces the primary idea succinctly.

Avoid vague language or cluttered wording. Your reader should immediately understand the topic.

• Clear: “Recycling programs reduce landfill waste by promoting reusable packaging.”
• Unclear: “Programs for recycling can be a good thing because it’s important.”

Tip #2: Keep It Simple and Direct

A topic sentence should be straightforward. Avoid complex structures and over-complicated phrasing.

Shorter sentences work best.

• Simple: “Exercise improves mental health through endorphin production.”
• Complicated: “One can expect to experience benefits in their mental state with exercise due to the generation of endorphins.”

Tip #3: Link to the Previous Paragraph

Create a smooth flow by connecting ideas to the paragraph before.

Transition words like “similarly,” “however,” or “in contrast” help show relationships.

• Linked: “Similarly, the agricultural industry is also impacted by climate change.”
• Disjointed: “Farmers are struggling with erratic weather patterns.”

Tip #4: Avoid Announcing Your Intentions

Steer clear of sentences like “In this paragraph, I will discuss…” They sound amateurish and reduce reader engagement.

• Natural: “Effective communication skills are crucial for career advancement.”
• Announcing: “This paragraph will explain why communication skills are important.”

Tip #5: Vary Sentence Structure

Using the same structure repeatedly can bore readers.

Mix up your approach by experimenting with different forms like questions, facts, and lists.

• Varied: “How does cultural background influence consumer behavior?”
• Repetitive: “Consumer behavior is influenced by cultural background.”

Tip #6: Be Specific, Not General

A vague topic sentence leaves the reader confused. Instead, provide specific information to establish clarity and interest.

• Specific: “Remote work improves productivity by reducing commute times.”
• General: “Remote work is beneficial for many reasons.”

Tip #7: Reflect Your Argument’s Tone

Match your topic sentence with the tone of your argument. For serious discussions, avoid informal language.

• Formal: “The socioeconomic impact of urbanization requires comprehensive policy solutions.”
• Informal: “The effects of city living need some fixing.”

Tip #8: Include a Controlling Idea

The controlling idea limits the scope of the paragraph, ensuring the reader knows what to expect next.

• With Control: “Social media marketing increases brand visibility through targeted campaigns.”
• Without Control: “Social media is important.”

Tip #9: Use Active Voice

Active voice is more engaging and dynamic. It also provides clarity.

• Active: “New policies will reshape healthcare accessibility.”
• Passive: “Healthcare accessibility will be reshaped by new policies.”

Tip #10: Make It Unique

Avoid using overused phrases or predictable statements. Offer a fresh perspective to captivate your reader.

• Unique: “Biodegradable packaging is transforming the fast-food industry.”
• Cliché: “The fast-food industry is changing with new trends.”

Tip #11: Create Curiosity

Tease your reader by leaving questions unanswered. Encourage them to keep reading for more.

• Curious: “What are the unexpected benefits of rising inflation rates?”
• Blunt: “Rising inflation rates have some positive effects.”

Tip #12: Support Your Thesis

Your topic sentence should align with your overall thesis. It will give your argument more coherence.

• Aligned: “Reducing plastic waste aligns with our sustainability goals.”
• Unaligned: “Plastic recycling is controversial.”

Tip #13: Focus on One Point

Don’t overwhelm readers with multiple ideas in one topic sentence. Stick to one clear concept.

• One Point: “Artificial intelligence streamlines data analysis.”
• Too Broad: “Artificial intelligence changes marketing, finance, and data analysis.”

Tip #14: Use Key Terms From the Prompt (if applicable)

If you are responding to an assignment or specific topic prompt, make sure your topic sentence directly incorporates relevant keywords.

• Key Terms Included: “Global warming solutions must involve international cooperation.”
• Lacks Terms: “Solutions for the environment require cooperation.”

Tip #15: Offer Context

Provide some context in the topic sentence to frame the discussion, giving the reader essential background information.

With Context: “As urbanization accelerates, city infrastructure struggles to keep up.” Without Context: “City infrastructure is lagging.”

Tip #16: Incorporate Comparisons

Comparisons can clarify complex concepts and give readers a familiar reference.

• Comparison: “Just as the printing press revolutionized communication, the internet has transformed modern commerce.”
• No Comparison: “The internet has transformed modern commerce.”

Tip #17: Present Solutions

Offering a solution at the start engages readers who are seeking actionable advice.

• Solution: “Installing solar panels reduces energy bills while cutting carbon emissions.”
• Problem-Only: “High energy bills are a widespread issue.”

Tip #18: Address Common Misconceptions

Challenge preconceived notions to spark curiosity and highlight the importance of your argument.

• Challenging: “Despite common belief, vitamin supplements aren’t always beneficial.”
• Reinforcing: “Vitamin supplements have benefits.”

Tip #19: Use Emotional Appeals

Appeal to the reader’s emotions to deepen their connection to your writing.

• Emotional: “Volunteering at shelters uplifts communities and transforms lives.”
• Neutral: “Volunteering at shelters is helpful.”

Tip #20: Avoid Redundancy

Ensure your topic sentence adds new value. Avoid repeating points covered elsewhere.

• New Value: “Stronger copyright laws are crucial for protecting intellectual property.”
• Redundant: “Intellectual property needs stronger protection.”

Tip #21: Ask a Thought-Provoking Question

Pose a question that makes the reader stop and think. This engages them immediately.

• Provocative: “How will automation reshape the global workforce?”
• Plain: “Automation is changing the global workforce.”

Tip #22: Include an Action Verb

Action verbs add momentum and urgency to your topic sentence. They make your point more dynamic.

• Active Verb: “Investing in renewable energy fosters long-term economic growth.”
• Lacks Action: “Renewable energy investments are beneficial.”

Tip #23: Paint a Picture

Use descriptive language to help readers visualize your point.

• Descriptive: “Increased droughts have turned fertile farmlands into arid deserts.”
• Bland: “Droughts are affecting farmlands.”

Tip #24: Use Parallel Structure

Parallel structure involves repeating similar grammatical forms.

It makes your writing rhythmic and easy to follow.

• Parallel: “Tackling pollution requires reducing emissions, cleaning waterways, and limiting waste.”
• Non-Parallel: “Tackling pollution requires emission reductions, waterways cleaning, and limiting waste.”

Tip #25: Emphasize Urgency

Highlight the time-sensitive nature of your argument to create urgency.

• Urgent: “Immediate action is needed to prevent further deforestation.”
• Calm: “Deforestation is a concern.”

Tip #26: Highlight Contrasts

Contrasting different ideas helps to emphasize your point and draw clear distinctions.

• Contrast: “While technology creates new jobs, it also disrupts traditional industries.”
• No Contrast: “Technology affects the job market.”

Tip #27: Lead with a Statistic

Start with a compelling number to catch the reader’s attention and back up your argument.

• Statistic: “80% of small businesses struggle to comply with data privacy regulations.”
• General Statement: “Small businesses struggle with data privacy.”

Tip #28: Build on Existing Knowledge

Assume the reader has some background knowledge and expand on it.

• Builds On Knowledge: “With the rise of remote work, companies are rethinking their office spaces.”
• Basic Information: “Remote work is changing office spaces.”

Tip #29: Start with an Anecdote

A brief anecdote adds a human touch, creating an immediate connection with the reader.

• Anecdotal: “After years of burnout, Sarah switched to a part-time schedule to improve her work-life balance.”
• Abstract: “Work-life balance is important.”

Tip #30: Use an Engaging Metaphor

A metaphor can illuminate your argument in an unexpected way.

• Metaphor: “Effective teamwork is the glue that holds successful organizations together.”
• Literal: “Effective teamwork is important for organizations.”

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.

Common pitfalls to avoid.

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?

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.

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.

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?”

How to Write a Good Topic Sentence

Last Updated: May 10, 2024 Fact Checked

This article was co-authored by Megan Morgan, PhD . Megan Morgan is a Graduate Program Academic Advisor in the School of Public & International Affairs at the University of Georgia. 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. This article has been fact-checked, ensuring the accuracy of any cited facts and confirming the authority of its sources. This article has been viewed 2,249,994 times.

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
• Type out all numbers under a ten. Thanks Helpful 0 Not Helpful 0

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.

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.

What is a Topic Sentence?

A topic sentence is the first sentence of a paragraph in an essay that introduces the main idea or topic of that paragraph. It serves as a roadmap for the reader, letting them know what to expect in the upcoming paragraph. 

Purpose of Topic Sentence

The purpose of a topic sentence is to clearly and concisely convey the main point of the paragraph to the reader. 

It helps to guide the reader through the essay, making it easier for them to follow the overall argument or narrative.

Features of a Good Topic Sentence

A good topic sentence has a few key features. Let’s take a look: 

• Expresses the main idea of the paragraph or essay clearly and concisely.
• Is specific and focused , avoiding vague or overly general statements.
• Introduces the main point and is typically located at the beginning of the paragraph or essay.
• Presents a claim or position that is arguable or debatable, which the rest of the paragraph or essay will support.
• Can be a complete sentence or a concise phrase that effectively conveys the main idea.
• Is relevant to the thesis statement and overall topic of the essay.
• Engages the reader by creating interest and highlighting the significance of the topic.
• Is well-written and avoids grammar and spelling errors.
• Provides a roadmap for the rest of the paragraph or essay by indicating what will be covered.
• Encourages coherence and unity in the writing by linking the paragraph or essay to the broader topic.

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."

What Is a Topic Sentence?

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 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.

How Many Sentences Are in a Paragraph, Really?

Have you ever found yourself staring at a blank page, wondering if your paragraph is too short, too long, or just right? Well, you're not alone in asking how many sentences are in a paragraph . It can be hard to tell whether you've provided enough information and if, most importantly, it is easy to read and effectively communicates your main point.

There’s no magic number, but there are certain rules that writers can follow to create solid compositions.

Paragraph Structure 101

How many sentences are in a paragraph, can a paragraph be one sentence long, when to write shorter paragraphs, when to write longer paragraphs, nailing the final sentence, when is the right time to start a new paragraph, 5 tips for writing the perfect paragraph.

A paragraph is like a well-balanced meal, complete with a main idea, details to savor and a satisfying conclusion. This distinct section of writing deals with a particular idea or theme and typically consists of several sentences that are related and organized around a central point.

Here are the core components of a paragraph.

• Topic sentence : This is usually the first sentence of the paragraph, boldly introducing the main idea or point. It’s like the person at a party who starts the conversation with an exciting story, grabbing everyone’s attention.
• Supporting sentences : These sentences are the loyal friends who chime in with more details, explanations or examples to back up the main idea. Think of them as the friends who add, "So true, I saw that too!"
• Concluding sentence : This sentence wraps up the idea of the paragraph and may provide a transition to the next paragraph. It’s like the smooth talker at the end who sums up the moral of the story, leaving everyone satisfied and ready for the next tale.

There is no hard-and-fast rule regarding paragraph length. There is a time and a place for short paragraphs and their longer counterparts (we'll get to this later).

Determining the perfect number of sentences in a paragraph is more of an art than a science, but some helpful guidelines exist. Generally, a paragraph contains three to five sentences. This range ensures you have enough space to introduce your main idea, support it with details and wrap it up neatly — all without overwhelming your reader.

Breaking Down an Example

If you're writing about the benefits of exercise, your paragraph might start with a topic sentence like, "Exercise is crucial for maintaining good health."

Follow with a few supporting sentences like, "It improves cardiovascular health and strengthens muscles. In addition to the physical benefits, exercise also boosts mental well-being."

Then, finish with a strong closing sentence, "Incorporating regular exercise into your routine can lead to a happier, healthier life."

So, how many words are in an average paragraph? The typical range is 100 to 200 words. Think of this as a comfortable size for your reader to absorb. In academic writing, a paragraph might be on the longer side to thoroughly explore a concept, while in casual writing, shorter paragraphs keep things snappy and engaging.

Remember, these are guidelines, not rigid rules. The key is to balance clarity, completeness and reader engagement, making your paragraphs just the right length to keep readers or target audience hooked and informed.

It's common to assume that a good paragraph should be at least three or four sentences long, but that is not always the case. A paragraph can be one sentence, especially in certain contexts — like creative writing or journalism — or when emphasizing a particular point.

For example, "And then, silence," is a short, one-sentence paragraph often used for dramatic effect or to highlight a moment in the narrative. A short paragraph like this can be particularly effective when the previous paragraph is on the lengthy side.

In more formal or academic writing, paragraphs typically contain multiple sentences to develop an idea fully, but there are still some rare instances of single-sentence paragraphs. For example, "The experiment failed," is a one-sentence paragraph that can be used to highlight a significant result or conclusion.

Shorter paragraphs can be very effective in various contexts. For instance, they are useful for emphasizing a point, as a short paragraph can draw attention to a key idea or conclusion, making it stand out from the surrounding text. Think of it as the literary equivalent of a mic drop.

A brief paragraph in creative writing or storytelling can heighten suspense or emphasize a sudden change or revelation, such as "And then, the lights went out." It’s like the plot twist nobody saw coming.

Improving readability is another important reason to use shorter paragraphs. In web writing or other forms of media, shorter paragraphs can help keep the reader engaged and make the text easier to digest. Imagine serving your readers bite-sized snacks instead of a five-course meal.

Shorter paragraphs are also helpful for introducing a new idea. Starting a new section or shifting to a new idea with a short paragraph can provide a clear break and signal a transition to the reader. It's like saying, "Hold on, new topic ahead!"

Lastly, shorter paragraphs in blogs or informal writing can create a more conversational and approachable tone, making the content more engaging for the reader. Think of it as chatting with a friend rather than lecturing a class.

Sometimes, it's good to give your readers a break, so don't be afraid to keep it short and sweet!

Longer paragraphs are like a hearty stew: Sometimes, you need that extra depth and richness. They’re great for diving into complex topics where you must provide detailed explanations, multiple examples and robust support for your points. This is especially useful in academic writing, research papers and detailed reports where a brief overview just won't cut it.

In narrative writing, longer paragraphs allow you to set the scene, develop characters and advance the plot without stopping every few sentences.

When presenting a nuanced argument, longer paragraphs help articulate intricacies and counterpoints effectively, keeping the text from becoming a patchwork quilt of ideas. Just make sure they stay focused and clear so your readers don’t get lost in the wordy wilderness.

The secret to a solid final sentence lies in its ability to encapsulate the main idea of the paragraph and leave a lasting impression. It should provide a sense of closure, tying together the key points discussed. Using impactful language or a thought-provoking statement can make the final sentence memorable.

For example, a strong final sentence in a paragraph about climate change could be, "Our actions today will determine the planet's future — so maybe skip that extra-long shower."

In a discussion about healthy eating, you might conclude with, "Remember, an apple a day keeps the doctor away, but only if you actually eat it."

Knowing when to break into a new paragraph is key for clarity. Start a new paragraph when introducing a new idea or topic, when you need to break up a long block of text to improve readability or when you want to emphasize a point.

Transitioning between different speakers in dialogue also requires a new paragraph. Whenever your writing takes a new direction, think of it as a cue for a fresh paragraph.

These tips will help you craft clear, cohesive and compelling paragraphs.

• Stick to one core idea. Each paragraph should focus on a single core idea, in the same way that a good joke has one punchline. For example, if you're discussing the benefits of exercise, don't suddenly veer off into your favorite cookie recipes.
• Create connections between sentences. Make sure your sentences flow logically from one to the next. Think of it like a conga line: Each sentence should seamlessly follow the previous one, keeping the party going smoothly.
• Use transition words. Transition words and phrases — such as "however," "therefore" and "for example" — guide your reader through your argument and signaling shifts between ideas.
• Include supporting details. Bolster your main idea with supporting details, examples and evidence. Imagine you're trying to convince someone that pizza is the best food; you'll need to include tasty details like, "With its ooey-gooey mozzarella cheese, herbaceous marinara sauce and crisp pepperoni slices, piping-hot pizza is the perfect meal."
• Conclude with a strong closing sentence. Wrap up your paragraph with a concluding sentence that reinforces the main idea and provides a sense of closure. It's like the final chord in a song, leaving your reader with a satisfying sense of completeness.
