To paraphrase without plagiarising, read the passage until you understand it, close the source, write the idea from memory in your own words and sentence structure, then compare with the original and add a citation. Changing a few words in the original sentence is not enough: a paraphrase must be new wording, a new structure and a clear citation. This guide shows you how to paraphrase without plagiarising step by step, with worked examples.
Paraphrasing is one of the most useful academic skills because it shows your marker that you understand a source, not just that you found it. It is also where many students accidentally fall into plagiarism.
What paraphrasing is (and is not)
A paraphrase restates a specific idea from a source in your own words, at roughly the same level of detail, with a citation. It is not:
- Swapping a few words for synonyms while keeping the original sentence shape.
- Rearranging the original clauses in a slightly different order.
- Using someone's idea without a citation because "the words are mine".
The idea still belongs to the author, so a paraphrase always needs a citation, even when every word is yours.
Paraphrase vs summarise vs quote
Paraphrase vs summarise vs quote is a common point of confusion. Each has a different job:
| Technique | What it does | Length compared to original | Citation needed | Best used when |
|---|---|---|---|---|
| Quote | Copies the exact words in quotation marks | Same | Yes, with page number | The exact wording matters (a definition, a legal phrase, a striking claim) |
| Paraphrase | Restates one specific idea in your own words | Similar | Yes (page often recommended) | You need a detailed point but want to show understanding |
| Summarise | Condenses the main ideas of a longer passage or whole source | Much shorter | Yes | You need the overall argument or findings, not the detail |
Most assignments should rely mainly on paraphrase and summary, with quotes kept for moments when the original wording genuinely matters.
How to paraphrase without plagiarising: the 6-step method
- Read the passage two or three times, and read the paragraphs around it so you understand the context.
- Understand it: explain the idea out loud or jot two or three keywords. If you cannot explain it, you are not ready to paraphrase it.
- Close the source: put it away or switch tabs. This is the step that prevents patchwriting.
- Write from memory: express the idea as you would explain it to a classmate, then adjust the tone to be academic.
- Compare your version with the original. Check that the meaning is accurate and that you have not reused distinctive phrases or the same sentence structure.
- Cite the source in your required style, including a page number if your style recommends it.
Academic paraphrasing techniques
These academic paraphrasing techniques work best in combination. Using only one usually produces something too close to the original.
Change the structure
Start the sentence from a different point, split one long sentence into two, or combine two short ones. Switching between active and passive voice also helps.
- Original shape: "Researchers found that X caused Y."
- New shape: "Y appears to be a consequence of X, according to..."
Change the word class
Turn verbs into nouns, nouns into verbs, or adjectives into adverbs.
- "The policy significantly reduced waiting times" becomes "The policy led to a significant reduction in waiting times."
Use synonyms carefully
Synonyms are useful but risky. Not every word has a true equivalent, and a thesaurus can change your meaning. Most importantly, keep specialist terms. Words like "photosynthesis", "inflation", "sepsis", "consideration" (in contract law) or "regression" have precise meanings. Replacing them with near-synonyms makes your work less accurate, not more original.
Change the emphasis
Lead with the part of the idea that matters most to your argument. This makes the paraphrase more original and more useful.
Worked example: good paraphrase vs patchwriting
Here is an original passage written for this guide (so you can practise freely):
Original: "Students who space their revision across several short sessions tend to remember material for longer than those who study the same content in one extended session. This advantage appears to increase when the gap between sessions is gradually extended, although the optimal spacing depends on how long the information needs to be retained." (Morgan, 2023, p. 14)
Patchwriting (not acceptable)
"Students who spread their revision across several brief sessions usually remember information for longer than those who study the same material in one long session. This benefit seems to grow when the gap between sessions is slowly increased, although the best spacing depends on how long the information must be remembered (Morgan, 2023)."
This is called patchwriting: the student has swapped individual words ("short" for "brief", "advantage" for "benefit") but kept the original sentence structure and order almost exactly. Even with a citation, many universities treat patchwriting as poor academic practice or plagiarism, and similarity checkers will usually highlight it.
Acceptable paraphrase
"Morgan (2023) argues that distributing study time over multiple shorter sessions leads to better long-term recall than a single long session. The effect may be stronger when intervals between sessions become progressively longer, but the ideal interval varies with how long learners need to retain the material (p. 14)."
Why this works:
- The sentence structure is new: it opens with the author and uses "distributing study time" as the subject.
- Word classes have changed ("remember" becomes "recall", "extended" becomes "progressively longer").
- The key concept is preserved accurately, including the condition at the end.
- It is clearly cited, with a page number.
Summary version
"Spacing study sessions out, ideally with growing gaps, improves long-term memory (Morgan, 2023)."
Notice how much shorter the summary is. It keeps the main point and drops the detail.
Integrating paraphrases with signal phrases and reporting verbs
A paraphrase reads best when you introduce it with a signal phrase that names the source and shows your stance. Reporting verbs carry meaning, so choose them deliberately:
| Purpose | Reporting verbs |
|---|---|
| Neutral | states, describes, notes, reports, observes |
| Author argues a position | argues, claims, contends, maintains, asserts |
| Author has evidence | demonstrates, shows, establishes, finds |
| Tentative findings | suggests, proposes, implies, indicates |
| You disagree or doubt | claims, alleges, assumes (used carefully) |
Examples:
- "Morgan (2023) demonstrates that spaced revision improves recall." (You accept the evidence.)
- "Morgan (2023) claims that spaced revision always outperforms cramming, but..." (You are about to challenge it.)
After a paraphrase, add your own sentence that explains its relevance or evaluates it. That is where your marks come from. See critical analysis in assignments for how to do this well.
AI paraphrasing tools and university rules
AI paraphrasing tools and "article spinners" are widely available, but use them with great care:
- Many universities restrict or ban them. Rules vary, so check your institution's academic integrity policy and your module guidance before using any AI tool.
- Disguising someone else's text is still plagiarism. Running a source through a rewording tool does not make the ideas yours, and doing so to avoid detection is academic misconduct.
- Output is often inaccurate. Tools frequently change specialist terms, distort meaning or produce awkward phrasing that markers notice.
- Detection is improving. Similarity checkers and AI-writing indicators are imperfect, but universities also look at writing style, drafts and viva conversations. Our guide to Turnitin and AI detection explains how these systems work.
The safest and most valuable approach is to build the skill yourself using the six steps above. If you use any tool for language support, follow your university's rules and declare it where required.
Common paraphrasing mistakes
- Forgetting the citation because the words are your own.
- Keeping the original sentence structure and swapping words (patchwriting).
- Paraphrasing a passage you have not understood, which often changes the meaning.
- Replacing technical terms with everyday synonyms.
- Stringing together paraphrases with no analysis of your own.

Frequently asked questions
Is paraphrasing plagiarism if I cite the source?
Not if it is a genuine paraphrase with new wording and new structure plus a citation. It can still count as plagiarism or poor practice if it is patchwriting, meaning the original sentence structure is kept with only a few words changed.
How much do I need to change when paraphrasing?
Change both the wording and the sentence structure, while keeping the meaning and specialist terms. A useful test is that your version should not look similar to the original when placed side by side, even though it says the same thing.
What is patchwriting?
Patchwriting is when a writer copies the original sentence pattern and replaces some words with synonyms. It often happens when students paraphrase with the source open in front of them, which is why closing the source before you write is so important.
Can I use an AI paraphrasing tool for my assignment?
Check your university's policy first, because many restrict or ban these tools for assessed work. Using a tool to disguise copied text is academic misconduct, and the output is often inaccurate, so developing your own paraphrasing skill is the safer choice.
Do I need a page number when paraphrasing?
It depends on the style. APA and many Harvard versions recommend a page number when you paraphrase a specific passage, and MLA includes one whenever the source has page numbers.
