What is a Topic Sentence in an Essay?

A topic sentence is a sentence that introduces the central idea of a paragraph. It should be written effectively to help the audience understand the main idea.

Each topic sentence in a paragraph should have a topic and a controlling idea to show where the information is heading. It also explains what the rest of the paragraph is all about.

Typically, it is stated at the start of each body paragraph. Most people considered it as the paragraph’s first line.

Purpose of a Topic Sentence

The following are the major purposes behind writing a topic sentence.

  • It makes a claim.
  • It gives an idea of what the paragraph is all about.
  • It relates the paragraph to the central argument of the essay.

Difference Between a Topic Sentence and a Thesis Statement

A topic sentence and a thesis statement have some clear differences. A thesis statement discusses what the whole paper is focusing on. It is a fact that you aim to prove or explain throughout the paper. However, a topic sentence also explains what a particular paragraph is about.

Moreover, a topic sentence is stated at the beginning of every paragraph, but the thesis statement comes at the end of the introduction.

For Example:

  • Thesis Statement: Capital punishment should be outlawed because it is immoral and does not deter crime
  • Topic Sentence:Capital punishment is immoral.
