What is the purpose of a conclusion in an essay?

The purpose of a conclusion in an essay is to summarize the main points discussed throughout the paper and reinforce the central argument. This part of the essay allows the writer to effectively remind the reader of the key ideas that were presented, tying them together in a cohesive manner. By reiterating the main arguments and insights, the conclusion helps to solidify the message the writer aims to convey. It's an opportunity to leave a lasting impression on the reader and emphasizes the significance of the topics covered.

Maintaining focus on summarizing and reinforcing ensures the conclusion provides clarity and closure, guiding the reader towards understanding why the arguments made were important. Introducing new information or evidence would disrupt this purpose and potentially confuse the reader, while simply restating the thesis without elaboration may not provide the depth and insight needed for a strong conclusion.
