What is a conclusion in writing?

A conclusion in writing serves as the final part of a piece, effectively summarizing the main points discussed throughout the text or providing a closing thought that encapsulates the overall message. It helps to reinforce the key ideas presented, giving the reader a sense of closure and understanding of the topic at hand. A well-crafted conclusion can also highlight the significance of the content, encouraging the reader to reflect or take further action based on what they have read. This summarization and closing function make it distinct from other components in writing, such as claims or introductions, which serve different roles in presenting arguments or setting the stage for the topic.
