The advice students hear most about paraphrasing is “put it in your own words.” Fine starting point. Also misleading. “Your own words” makes the task sound like translation: swap out the vocabulary, rearrange the sentence structure, done. Paraphrasing is a thinking problem first.
The failure mode has a name: patchwriting. A patchwritten paraphrase keeps the original sentence structure and substitutes synonyms for important words. It looks different on the surface, reads much like the source, and may still be plagiarism even with a citation. The writer has changed the wording without working through the idea.
What I try to give students is a purpose-first question: before you paraphrase anything, ask why you’re using this source at all. What claim does it support? What part of it matters for your argument? Your answer should shape how you rebuild the idea.
A source used for historical context gets paraphrased differently from the same source used to complicate a theoretical assumption. The variation shows that the writer understands the source’s function.
This connects to Writing is the thinking: weak paraphrasing often indicates that the writer does not yet know why the source matters. Mechanical substitution can resemble engagement while avoiding that decision.
