In word: What's the difference between captions, footnotes, endnotes and annotations?

Captions are names and numbers added to pictures, tables, charts, formulas and other items. Footnotes are a way to indicate the source of information and add notes to articles. Endnotes are supplementary notes to the text, usually located at the end of the document, listing the source of quotations, etc. Annotation is a common reading method. When reading, write your own thoughts and difficult questions in the blank space of the book, which will help you understand and think deeply.

The content of annotations can be roughly divided into three categories:

1. Note: When reading, if you encounter unfamiliar or difficult words, look up the dictionary and reference books, find out the meaning, point out the source and write them in the blank.

2. Abstract: Think while watching, summarize the central idea in concise language, grasp the context of the article, and prompt the language characteristics.

3. Comments: There will be various ideas, opinions and questions when reading, which can be written in the blank space.
