We need to clarify the difference between the word "paraphrase" and "rephrase"?
As you might see, paraphrasing is more about adapting the information you already have: modify it in order to better understand the meaning of it without adding something new to it. Rephrasing at the same time is more about improving the content for the purpose of clarification, which means you can even add new information here to get the better idea (Qurora).
