Language term
Topic sentence
The sentence that states the main point of a paragraph, usually at its start.
What it means
A topic sentence states the main point or focus of a paragraph. It usually appears at or near the beginning. It tells the reader what the paragraph will be about.
The sentences that follow develop, explain or support it with detail, evidence and examples. A clear topic sentence gives a paragraph unity and direction. The reader is never left wondering what the point is.
In analytical and persuasive writing, strong topic sentences act as signposts. They guide the reader through an argument one clear idea at a time.
Why it matters in the exam
In writing tasks, clear topic sentences keep your paragraphs focused and your argument easy to follow. Examiners reward this as structure and organisation. In analytical essays, a topic sentence that answers the question keeps each paragraph relevant.
Opening paragraphs with a clear point and then supporting it is one of the simplest ways to raise the quality and coherence of your writing.
Example
Opening a paragraph with The town's transport problems begin with its narrow roads tells the reader exactly what the rest of the paragraph will explain.
How to use it
Begin each paragraph with a sentence that states its main point clearly. Then follow it with explanation, evidence and detail that develop that point. In an essay, make the topic sentence address the question directly.
Check that everything else in the paragraph supports it, and cut anything that drifts, so each paragraph stays unified around one clear idea.
