What is the paragraph doing?
What makes a strong topic sentence
It states one main idea
A topic sentence commits the paragraph to a single point. If your sentence contains two unrelated claims joined by 'and', you probably have two paragraphs — split them.
It takes a position or sets a scope
In argumentative writing the topic sentence makes a sub-claim your evidence must defend; in expository writing it defines exactly what slice of the topic the paragraph covers. Either way, it should be specific enough that a reader could predict what comes next.
It connects back to the thesis
Each topic sentence is a link in the essay's chain of reasoning. A reader should be able to see how the paragraph's point advances the essay's central claim — if the connection is not obvious, add a transitional phrase that makes it explicit.
It previews, it does not prove
Save the statistics, quotations, and examples for the sentences that follow. The topic sentence's job is to make the claim; the rest of the paragraph earns it.
Frequently Asked Questions
- What is a topic sentence?
- A topic sentence is usually the first sentence of a body paragraph. It states the paragraph's one main idea and signals how that idea supports your thesis. Everything else in the paragraph — evidence, examples, analysis — should relate back to it.
- How does this generator work?
- You enter your paragraph's main idea and a supporting point, pick a stance, and the tool combines them into six academic sentence frames — fixed templates with your words slotted in. It is not AI: the frames show you proven structures, and you adapt the wording so the sentence reads naturally in your own voice.
- What is the difference between a topic sentence and a thesis statement?
- The thesis statement makes the central claim of the whole essay and appears in the introduction. A topic sentence makes the claim of a single paragraph and appears at the start of that paragraph. Each topic sentence should support the thesis, like a sub-claim.
- Which stance should I choose?
- Choose 'Argue' for persuasive and argumentative paragraphs that defend a position, 'Inform' for expository paragraphs that explain a concept, and 'Compare' for paragraphs that weigh similarities and differences. The stance changes the sentence frames so the structure matches the paragraph's job.
- Can I use the generated sentence word for word?
- Treat it as a draft. Because the frames are templates, the raw output can sound stiff or slightly off-grammar depending on how you phrased your inputs. Read the sentence aloud, smooth the wording, and make sure it accurately previews what your paragraph actually says.
