Is a summary like outline?

A summary is not like an outline. An outline is a hierarchical structure that organizes the main points and supporting details of a piece of writing. It typically includes Roman numerals for main points, capital letters for subpoints, and Arabic numerals for supporting details. A summary, on the other hand, is a brief overview of the main points of a text, without the detailed structure of an outline. It typically includes a few sentences that capture the essence of the text.
