A summary is a brief overview of a larger piece of content, such as a book, article, or speech. It captures the main ideas and key points while omitting unnecessary details. Summaries help readers quickly understand the essential information without having to read the entire text. Creating a summary involves identifying the core message and important arguments presented. This process is useful in various fields, including education, business, and research, as it allows individuals to grasp complex information efficiently. Summaries can also aid in studying and retaining knowledge about topics like history, science, or literature.
