What is the primary function of an essay's conclusion?

The primary function of an essay's conclusion is to restate the thesis and summarize the main points. This is essential because the conclusion ties the entire argument or discussion together, reinforcing the central message or argument presented in the essay. By restating the thesis, you remind readers of the core premise that the essay has sought to prove or discuss. Summarizing the main points allows you to highlight the key elements of your argument, making it easier for readers to recall the critical aspects of your writing.

A strong conclusion also provides closure to the discussion, giving readers a clear understanding of the significance of your analysis and how your points intersect to support the thesis. Instead of introducing new ideas, which can confuse readers and dilute the focus of the essay, the conclusion aims to consolidate what has already been discussed, leaving readers with a clear and succinct recap of the argument. This helps ensure that the essay is coherent and leaves a lasting impression.
