Home » Essay guidelines » How to write a topic sentence
The topic sentence, which is generally the opening sentence of a paragraph, presents the paragraph’s main idea and establishes the tone.
In research papers, where the topic changes between paragraphs, a topic sentence is extremely crucial. Knowing how to construct a topic sentence is therefore essential for any student or writer.
Purpose of a topic sentence
- The purpose of a topic sentence is to inform readers about the rest of the paragraph.
- Topic sentences connect paragraphs in a way that flows well and makes reading easier.
- All subsequent sentences must include additional information on that statement, either by proving it with facts or by describing it in greater depth.
- Topic sentences must also be related to the research paper’s argument. The thesis statement acts as a road map for the reader or listener, indicating where you’re heading with this material and how you’re going to handle it.

Pro tip
You can also utilize your topic sentences to easily transition between paragraphs and illustrate the links between your ideas to create a well-structured argument.
Topic sentence vs. thesis statement
Both thesis statements and topic sentences help readers comprehend your research paper’s structure and main arguments. However, they are different in a few respects.
- The thesis statement should be in the first paragraph, and topic sentences should be at the start of each body paragraph.
- There will be only one thesis statement in each research paper; however, the number of topic sentences will be determined by the number of body paragraphs.
- The topic sentence informs your reader about the topic of the paragraph. A body paragraph should be assigned to each argument in your thesis.
Steps on writing a topic sentence
Topic sentences are developed throughout the writing process. Follow these steps to ensure that each topic sentence and paragraph supports your thesis statement.
Step 1 – Create a thesis statement
Thesis statement example
By regulating blood sugar, lowering refined food intake, and restricting excessive protein intake, the ketogenic diet may help to reduce the prevalence of illness.Step 2 – Create an outline and start writing topic sentences
Next, sketch out the outline of your paper, including what you’ll say in each paragraph and what evidence you’ll use.
- The topic sentences should be more precise than the thesis statement, but they should always be connected to it.
Topic sentence example
The ketogenic diet has been shown to assist people in regulating their blood sugar levels.Step 3 – Enrich your arguments with evidence
The rest of the paragraph should follow the topic sentence and build on it with facts, examples, or reasoning.
- Everything you write should be related to the topic sentence’s main idea. In other words, you can reference some research papers and statistics to back up your claim regarding the benefits of the ketogenic diet.
Step 4 – Polish your topic sentences
The majority of topic sentences begin as basic assertions. However, you should edit them as you write to ensure that they correspond to the content of each paragraph.
- A good topic sentence is detailed enough to offer a clear idea of what to expect from the paragraph but it should not be so detailed to reveal everything.
Types and examples of topic sentences
It’s helpful to understand the many forms of a topic sentence before learning how to write one. We’ll go through the different categories and give some examples of topic sentences.
Simple statement
The most basic form of a topic sentence is this one, in which the author makes a broad assertion upon which the rest of the paragraph elaborates.
Example
There are several reasons why India has the worst pollution levels in the world.Question form (Interrogative)
As long as you don’t steer away from the subject, starting a paragraph with a question is a wonderful approach to get the reader engaged and involved.
Example
How many countries have plans in place to deal with rising sea levels?Complex form
You might want to utilize a complex topic sentence if you have a complicated topic with numerous concepts. Even though they are still considered “statements,” they include more than one primary point.
Example
While the Internet has provided many new opportunities for organizations, companies must now consider updating their cybersecurity systems more than ever before.Transitional form
While all topic sentences must deal with transitions to some extent, they can also be simply transitional in some circumstances. These are most effective when the topic shifts dramatically, as they bring attention to the transition (also see transition words and phrases).
Example
If a random apple had not fallen upon the head of a young Isaac Newton, the world would not be the way it is today.Introduction of an argumentative essay
Here are a few specific pointers for topic sentences.
Pique the reader’s attention with a hook
A “hook,” or anything that makes people want to read more, is frequently included in good topic sentences. While some are more frequent than others, there are a number of techniques to entice your readers:
-
Surprising findings
Despite the massive turnout, only 1% of the teams were able to finish the first task.
-
Mysterious questions
What eventually persuaded the senator to change his mind?
-
Emotional appeal
Find a balance between general and specific
Learning how much to include and how much to leave for the rest of the paragraph is one of the most difficult aspects of creating topic sentences. You should:
- Explain just enough so that the reader understands what the paragraph is about and, perhaps, becomes intrigued.
- Everything else may be saved for the supporting sentences.
Be clear!
Clarity is the most crucial aspect of topic sentences. Even if you pique the reader’s interest and make them want to read more, it won’t matter if they don’t understand what they’re reading. Make use of common academic words, active and passive voice, and verb tenses to be more clear.
Reminders and helpful hints
- To keep your reader engaged, give your topic sentence a clever hook.
- Use the topic sentence to connect a new paragraph to the paper’s thesis statement.
- To break up the monotony of style, make the topic sentence a question.
- To connect two paragraphs, use transitions in your topic sentence.

Essay Topic Ideas
In the writing process, generating ideas is the least systematic and most innovative step. Now, let’s continue with the steps you can follow in order to find a topic for your academic essay.
Differences between US and UK English
Your English style should always be consistent throughout the process of writing your research paper, essay, or dissertation. Even though there are more than 160 different English dialects worldwide, American English and British English are known as the most commonly used styles.
Active and passive voice in writing
Active voice and passive voice define how an action is told. While the subject is doing the action in active voice, the person or thing that receives the action comes before the verb in passive voice. You should use the correct verb tense to create a passive voice.
First-person pronouns in academic writing
There are many different perspectives on using first-person pronouns (I, we, our, etc.) in academic writing among various disciplines. While many experts advise using first-person pronouns even in fields of science, there is no consensus.
Common phrasal verbs in writing
The two lists below show commonly used phrasal verbs in academic writing and their one-word synonyms. Although it is academically acceptable to use phrasal verbs, you might want to switch them to their one-word synonyms to make your writing diverse and more professional.
