How to Paraphrase Without Plagiarising (With Before-and-After Examples)
Short answer: to paraphrase safely, read the source, put it away, write the idea in your own words and your own sentence structure, then compare with the original and add a citation. Swapping a few words for synonyms is not paraphrasing — it is patchwriting, and universities treat it as plagiarism.
Paraphrasing is the skill markers most want to see: it proves you understood a source well enough to use it in your own argument. It is also where many students accidentally plagiarise, because the line between "my words" and "their words, lightly edited" is easy to cross when you are writing with the source open in front of you.
The 4-step method
- Read the passage until you can explain its point out loud without looking.
- Close the source. Write the idea from understanding, in the order and structure that suits your paragraph.
- Compare your version with the original. If any string of distinctive words survives, rewrite that part.
- Cite it. A paraphrase always carries a citation — the idea is still theirs. Formats are in our Harvard referencing guide.
Before and after
The weak version changes vocabulary but keeps the original's structure and phrasing skeleton. A marker — or similarity software — will flag it.
Different structure, different order, genuinely the writer's own sentences — and the citation still credits the idea.
Four techniques that change structure, not just words
- Change the sentence shape: turn a long sentence into two short ones, or merge two into one.
- Change the voice: active to passive or the reverse ("researchers measured X" → "X was measured").
- Start from a different point: if the original leads with the cause, lead with the effect.
- Use the idea, not the passage: combine the point with a second source or your own example — synthesis is the strongest form of paraphrase.
When to quote instead
Quote, with quotation marks and a page number, when the exact wording matters: a definition, a law or policy line, a striking claim you intend to analyse, or wording you will critique. Everything else, paraphrase. A useful rule: if your assignment has more than two or three quotes per 1,000 words, you are probably quoting what you should be paraphrasing.
A second worked example — a harder passage
Notice what the strong version does: it changes the entry point (the marketing claim), splits one long sentence into two, replaces the abstract noun "retrieval practice" with the plain action "self-testing", and moves the citation to the end, where it supports the whole rebuilt idea. None of that comes from a thesaurus — it comes from understanding the point well enough to rebuild it.
Why patchwriting happens — and the fix
Patchwriting is rarely dishonest. It usually happens when a student writes about material they only half understand: the source's sentences feel safer than their own, so they lean on the original's skeleton while changing its clothes. The durable fix is therefore not a stricter warning but better comprehension — explain the passage aloud, to an imaginary classmate, before you write it. If you cannot explain it, you are not ready to paraphrase it; reread it, or choose a source you do understand. Markers know this pattern well, which is why first patchwriting offences are usually treated as a skills problem — and why fixing the comprehension step, not the vocabulary step, is what actually removes the risk.
How markers spot patchwriting
Patchwriting has a texture markers recognise within a paragraph: the vocabulary level jumps up and down between sentences, specialist phrases appear once and are never used again, and the sentence rhythm suddenly mirrors a textbook instead of the student's own voice from the previous page. Similarity software flags the matching strings, but a marker often suspects it before any report is opened. Writing from understanding produces the opposite texture — even, plain, and consistent — which is why the comprehension fix above protects you in both checks.
The 60-second self-check
- Cover test: cover your paraphrase and say the same point aloud, differently, without looking. If you cannot, it may not be yours yet.
- Overlay test: do any four or more consecutive words match the original (excluding names and technical terms)? Rewrite those spots.
- Structure test: does your sentence start where theirs started and end where theirs ended? Move the starting point.
- Citation test: is a citation attached to the idea, in the same paragraph? If not, add it now.
Paraphrasing sits in the drafting stage of the full process — see how to write an assignment step by step — and it is worth a final check in the referencing pass of the proofreading checklist before you submit.
Frequently asked questions
How much do I need to change for a paraphrase to be safe?
There is no safe percentage. The test is whether both the words AND the sentence structure are genuinely yours, and whether the idea is cited. If your version could be overlaid on the original with the same skeleton, rewrite it.
Do I still need a citation if everything is in my own words?
Yes. Citations credit ideas, not just wording. An uncited paraphrase is one of the most common forms of plagiarism universities detect.
Can I paraphrase with the source open in front of me?
You can, but it is the most common cause of accidental patchwriting. Read, close, write from understanding, then compare — the closed-source method is slower for one sentence and faster for the whole assignment.
