Question

Copywriting

Help to understand what is copywriting and rewriting

Answer 1

Copyright - writing texts from scratch, there is only a topic and key phrases.
A rewrite is a rewritten text. That is, there is a text (it is no longer unique) and the rewriter rewrites it so that the meaning remains, but the text becomes unique.

Answer 2

Copyright - initially - an author's, advertising text that can sell something.
Rewriting - a banal replacement of words, paraphrasing, changing the structure of the text
