What is the process of changing a paragraph called?

There isn't a single, specific term for the process of changing a paragraph. It depends on what kind of changes you're making:

* Revision: This is a general term for making changes to improve a paragraph, whether it's for clarity, conciseness, flow, or adding more detail.

* Editing: This focuses on correcting grammar, punctuation, and spelling errors, and ensuring the paragraph is consistent with a style guide.

* Rewriting: This involves completely changing the content, structure, or style of the paragraph.

* Polishing: This involves making subtle changes to improve the overall quality of the paragraph, such as refining word choices or sentence structure.

The specific term you use will depend on the context and the nature of the changes you're making. For example, you might say you're "revising" a paragraph to make it clearer, "editing" it to fix a grammatical error, or "rewriting" it to completely change its meaning.
