The Three-Part Essay

An essay is a piece of academic writing made of several paragraphs organised around one main argument. Almost every essay has three parts:

PartWhat it does
Introductionintroduces the topic, gives background, states the thesis
Main bodydevelops the argument in several paragraphs, one idea each
Conclusionsummarises the main points and adds a final comment

The introduction often has a "funnel" shape: it begins with broad, general statements and gradually narrows down to the specific thesis statement. The conclusion does the reverse — it begins specific and widens out to a final comment.

Tip: Think of the essay as a journey: the introduction leads the reader in (general → specific), the body does the work, and the conclusion leads the reader out (specific → general).

Common mistake: Starting an essay straight with the thesis and no background. Lead the reader in with one or two general statements first.
