Both paragraphs and essays must end with a conclusion, but the type of conclusion differs. Paragraphs must end with a concluding sentence that states the basic point of the paragraph. It should not rephrase or reiterate the topic sentence. Essays end with a conclusion paragraph that summarizes the content of the essay and reiterates the thesis statement with different phrasing. The conclusion paragraph usually revisits the points introduced in the supporting paragraphs to prove to the reader that, from the writer's point of view, the thesis statement was correct.
