What is the primary purpose of a conclusion in an essay?

The primary purpose of a conclusion in an essay is to summarize the main points and reinforce the thesis or main argument. This section serves to wrap up the discussion presented in the body of the essay, reiterating the key arguments and insights that have been developed. By revisiting the thesis and highlighting the significant findings or arguments, the conclusion provides a sense of closure and completeness to the reader. It also emphasizes the importance of the ideas discussed, often encouraging the reader to reflect on them further or consider their implications. This reinforces the writer's message and leaves a lasting impression as the essay concludes.
