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

The primary function of a conclusion in an essay is to summarize the main points and reinforce the thesis. This part of the essay serves to remind the reader of the key arguments that support the main idea or thesis presented throughout the text. By succinctly restating these points, the conclusion helps to solidify the reader's understanding and provides a final perspective on the topic discussed.

Additionally, a strong conclusion may also emphasize the significance of the arguments and suggest implications or further areas of exploration. It effectively ties together the entire essay, creating a sense of closure for the reader, rather than introducing new information or arguments, which could confuse or overwhelm them.
