When you rewrite the main ideas of a story article or lecture in shorter form, you are creating a summary.

Here are some other terms you might use:

* Abstract: This is often used for academic papers and articles.

* Synopsis: This is commonly used for film or book descriptions.

* Cliff notes: This is a colloquial term for a very brief summary, often used for schoolwork.

* Recap: This is typically used for summarizing a previous event or episode in a series.

No matter what term you use, the goal is the same: to capture the most important information from the original source in a concise and understandable way.
