What is the function of a conclusion in a persuasive essay?

The function of a conclusion in a persuasive essay is to summarize the main points and reinforce the thesis. This component of an essay serves as the final opportunity for the writer to remind the reader of the arguments presented throughout the piece. By reiterating the key ideas, the conclusion helps to solidify the main argument in the reader's mind and emphasizes the importance of the position taken by the writer.

A strong conclusion often restates the thesis in light of the arguments made, creating a cohesive wrap-up that encourages the reader to embrace the writer's perspective. This process helps to leave a lasting impression, urging the audience to act or reconsider their viewpoints.

In contrast, introducing new ideas would detract from the conclusion's purpose by confusing the reader rather than reinforcing the established arguments. Presenting counterarguments in the conclusion could also undermine the writer's stance instead of solidifying it, and adding extra details may distract from the primary focus intended for a conclusion, which is to summarize and reinforce the main message.
