What is a summary?

A summary is a brief overview of the main points or ideas in a written work or presentation. It highlights the key information in a shorter version, while still retaining the essence of the original text. The purpose of a summary is to provide the reader with a quick understanding of the material, usually in order to help them decide whether or not to read further or to retain important information. A good summary is clear, concise, and accurately represents the original work.
