What is the purpose of a conclusion in a piece of writing?

The conclusion in a piece of writing serves the purpose of summarizing the main points and providing closure to the reader. It ties together the key ideas presented throughout the work, reinforcing the central messages and themes. By summarizing the main points, the conclusion helps to remind the reader of what has been discussed, ensuring that they leave with a clear understanding of the content. Additionally, it gives a sense of completion and finality, which is important for the reader to feel that the narrative or argument has come to a logical and satisfying end. This aspect of concluding helps to emphasize the importance and relevance of the discussion, leaving a lasting impression on the reader.
