Paraphrasing — expressing someone else’s idea in your own words — is a fundamental skill in academic writing. Done well, it demonstrates that you have genuinely understood a source and can engage with it critically. Done poorly, it slides into plagiarism, even when that is not the intention. The problem is that many students believe they are paraphrasing correctly when they are not. Swapping a few words for synonyms while keeping the same sentence structure is not paraphrasing — it is patchwriting, and Turnitin will still flag it.
The line between effective paraphrasing and accidental plagiarism is one that trips up a significant number of students, and understanding where it lies can protect your academic record. This guide explains the difference clearly and gives you practical techniques for paraphrasing effectively.
Quick Answer
Effective paraphrasing means genuinely restating an idea in your own words and sentence structure — not simply substituting synonyms. You must still cite the original source. If your paraphrase is too close to the original, it is patchwriting — a form of plagiarism.
What Is Paraphrasing?
Paraphrasing is the process of restating another person’s idea, argument or finding in your own words, without changing the meaning. It is different from quoting, which involves reproducing the original text exactly (usually in quotation marks). Paraphrasing is used in academic writing when you want to engage with a source’s ideas without using their exact words — which demonstrates comprehension and allows you to integrate the idea more naturally into your own argument.
Good paraphrasing is not just about changing words. It requires you to genuinely understand the source material, set it aside, and then express the same idea freshly in your own language and sentence structure.
Paraphrasing vs Plagiarism — Where Is the Line?
✓ Effective Paraphrasing
Completely rewritten in your own words
Different sentence structure from original
Captures the meaning accurately
Original source cited
Demonstrates genuine understanding
✗ Plagiarism / Patchwriting
Same or very similar sentence structure
Only synonyms substituted
Words rearranged but not rewritten
Too close to the original wording
Flagged by Turnitin even if cited
What Is Patchwriting?
Patchwriting is a specific form of inadequate paraphrasing in which the writer makes minor surface changes to a source text — swapping individual words for synonyms, changing tense or word order — while retaining the original sentence structure and logic. It is considered a form of plagiarism at most UK universities because it does not represent genuine engagement with the source material.
Patchwriting is often unintentional. Many students genuinely believe they are paraphrasing when they are actually patchwriting — because they have not been taught the distinction. Turnitin detects patchwriting by comparing not just individual words but sentence-level patterns, which means a patchwritten passage may still produce a significant similarity score even when every individual word has been changed.
Important
Citing the original source does not make patchwriting acceptable. If your paraphrase is too close to the original, it is still considered plagiarism regardless of whether it is referenced. The issue is the similarity of the language, not the attribution.
How to Paraphrase Effectively — Step by Step
Step 1 — Read and Understand
Read the original source carefully until you genuinely understand what it is saying. If you do not understand it, you cannot paraphrase it — you can only copy it. Read it more than once if needed and look up any terms you are unfamiliar with.
Step 2 — Put the Source Away
This is the most important step. Close the book, turn over the page, or scroll away from the text. Do not look at it while you write your paraphrase. If the source is in front of you, you will inevitably drift toward its wording.
Step 3 — Write the Idea in Your Own Words
Write what you understood the source to be saying, using your own vocabulary and your own sentence structure. Think about what the idea means, not about how the original author expressed it. Your version should sound like you, not like the source.
Step 4 — Compare with the Original
Now look back at the original. Check that your paraphrase accurately captures the meaning. If your version is too close to the original wording or sentence structure, rewrite it further. If it is accurate but written differently, you are done.
Step 5 — Add Your Citation
Add the appropriate in-text citation for the source you have paraphrased. Paraphrasing still requires citation — you are using someone else’s idea, even if not their exact words.
Examples: Plagiarism, Patchwriting and Effective Paraphrasing
Original text:“Students who engage in regular self-testing recall significantly more material than those who simply re-read their notes, suggesting that retrieval practice is a more effective study strategy than passive review.”
✗ Plagiarism (no citation, copied text)
“Students who engage in regular self-testing recall significantly more material than those who simply re-read their notes, suggesting that retrieval practice is a more effective study strategy than passive review.”
⚠ Patchwriting (cited but too close to original)
“Students who regularly test themselves remember far more content than those who merely re-read their notes, indicating that retrieval practice is a more efficient learning technique than passive reading (Smith, 2020).”
“Research suggests that actively testing one’s own knowledge yields better long-term retention than reviewing material passively, making self-quizzing a more productive approach to study (Smith, 2020).”
Do You Still Need to Cite a Paraphrase?
Yes — always. Paraphrasing does not remove the need to acknowledge the original source. The idea still belongs to the original author, even when expressed in your own words. Failing to cite a paraphrase is plagiarism because you are presenting someone else’s idea without attribution.
The citation format depends on your referencing style — Harvard, APA, MHRA and so on. In Harvard referencing, a paraphrase citation takes the form: (Author, Year) — for example, (Jones, 2019). For guidance on in-text citation, see our guide on understanding in-text Harvard referencing.
If you are struggling with paraphrasing or concerned that your current paraphrasing is too close to your sources, our professional paraphrasing service rewrites flagged or over-close passages in genuine, original human language while preserving your meaning. You can then run a plagiarism check to confirm your similarity score is within your institution’s acceptable range before submitting. If you are also concerned about AI detection scores, our AI checking service uses Turnitin to give you a full AI detection report before submission.
Frequently Asked Questions
Is paraphrasing plagiarism?
Paraphrasing is not plagiarism if it is done correctly — which means genuinely rewriting the idea in your own words and sentence structure, and citing the original source. However, inadequate paraphrasing (patchwriting) that stays too close to the original wording is considered a form of plagiarism, even when cited.
Does Turnitin detect paraphrasing?
Turnitin can detect patchwriting — paraphrasing that is too close to the original. It compares sentence-level patterns, not just individual words, which means swapping synonyms while keeping the same structure may still generate a similarity flag. Genuine, substantially rewritten paraphrasing is much less likely to be flagged.
How different does a paraphrase need to be?
There is no specific percentage or word count threshold — the standard is that the paraphrase should be written in your own genuine language and sentence structure. A practical test: if someone compared your version with the original side by side, would they see a genuinely different piece of writing, or simply a rearranged version of the same text? Aim for the former.
Can I paraphrase without reading the full source?
No. You cannot accurately paraphrase a source you have not fully understood. Attempting to paraphrase based on a skim read almost always results in patchwriting or inaccurate representation of the original — both of which cause problems for your academic integrity and your argument.
Is it better to quote or paraphrase in academic writing?
In most UK academic writing, paraphrasing is preferred over quoting. Over-reliance on direct quotations suggests that you have not fully engaged with the source material. Reserve direct quotes for when the exact wording of the original is significant — for example, when analysing language itself, or when the precise phrasing would be lost in translation.
Summary
Effective paraphrasing means genuinely rewriting an idea in your own words and sentence structure — not just substituting synonyms
Patchwriting (staying too close to the original) is a form of plagiarism even when cited
Always put the source away before writing your paraphrase
Always cite the original source even when paraphrasing
