The act of putting someone else’s ideas or words into your own words is called paraphrasing, rephrasing, or rewording. Even though they are often used interchangeably, the terms can mean slightly different things:
Paraphrasing is restating someone else’s ideas or words in your own words while retaining their meaning. Paraphrasing changes sentence structure, word choice, and sentence length to convey the same meaning.
Rephrasing may involve more substantial changes to the original text, including changing the order of sentences or the overall structure of the text.
Rewording is changing individual words in a text without changing its meaning or structure, often using synonyms.
