Frequently Asked Questions
A topic sentence is the first sentence of a paragraph that states the main idea or focus of that paragraph. It serves as a mini-thesis for the paragraph, telling readers what to expect. A strong topic sentence is specific, relates to the overall thesis, and provides a clear direction for the supporting sentences that follow.
A good topic sentence should: 1) State the main point of the paragraph clearly, 2) Be specific enough to be covered in one paragraph, 3) Connect to your thesis statement, 4) Avoid being too broad or too narrow, 5) Engage the reader's interest. It should introduce your idea without giving away all the details.
Topic sentences are typically placed at the beginning of a paragraph, but they can also appear at the end (for dramatic effect) or in the middle (when building up to a point). In academic writing, placing the topic sentence first is most common as it immediately tells readers what the paragraph is about.
A thesis statement presents the main argument of your entire essay and typically appears in the introduction. A topic sentence presents the main idea of a single paragraph. Think of the thesis as the "big picture" claim, while topic sentences are the supporting claims that help prove your thesis.
A topic sentence should typically be one sentence, ranging from 15-25 words. It should be concise enough to be clear but detailed enough to convey the paragraph's main point. Avoid overly complex sentences that try to do too much—save the details for the supporting sentences.
