A summary is a brief overview that captures the main ideas of a larger piece of content, such as a book, article, or speech. It distills the essential points, allowing readers to grasp the core message without having to read the entire work. Summaries are useful for studying, reviewing, or sharing information quickly. Creating a good summary involves identifying key themes and important details while omitting unnecessary information. For example, when summarizing a novel like Pride and Prejudice by Jane Austen, one would focus on the main characters, their relationships, and the central conflict, providing a clear snapshot of the story's essence.
