Paraphrasing without plagiarising

What a paraphrase actually is

It restates someone's idea in your own words and your own sentence structure, at roughly the same length as the original, with a citation. The citation is not optional — a paraphrase credits an idea, and an uncited paraphrase is plagiarism regardless of how completely reworded it is.

The point is not disguise. It is demonstration: putting an idea in your own words shows that you understood it, which quoting does not. That is why markers prefer paraphrase to quotation for most purposes.

It also lets you compress, combine and position an idea inside your own argument in a way a quotation cannot. A paragraph built from three paraphrased sources is doing analytical work; the same paragraph built from three quotations is doing assembly.

The method that works

Six steps. The third is the one that makes the difference and it is the one people skip.

• Read the passage until you can state its point without looking.
• Note the key terms that cannot be changed — technical vocabulary, named concepts, proper nouns.
• Close the book, or cover the text. This is the step that matters.
• Write what it said, in your own words, in whatever structure suits your paragraph.
• Reopen the original and check for accuracy — not for similarity, for accuracy. Have you changed the strength of the claim, dropped a qualifier, or added something?
• Add the citation, with a page number if the passage is specific.

Why closing the book is not optional

With the original in front of you, your brain works sentence by sentence, and the result inherits the original's structure however many words you change. That inheritance is what markers and similarity software both detect.

Closing it forces you to work from the idea instead. The sentence you then write is shaped by your paragraph's needs — the point you are making, the sentence before it, the argument you are building — rather than by someone else's paragraph.

This is also why paraphrasing feels harder than it should when done properly. It is harder. It involves understanding something well enough to restate it, which is the actual work of academic reading.

Patchwriting: the grey zone

Patchwriting means keeping the original's sentence structure and substituting synonyms. It usually happens without dishonest intent, by students working with the source open, and it is the single most common form of plagiarism in undergraduate work.

Misconduct panels treat it as plagiarism. Some institutions distinguish it as poor academic practice on a first occasion, particularly for first-year and international students, and the distinction is a matter of penalty rather than of category.

It is easy to detect, and not only by software. A marker reading a paragraph whose vocabulary suddenly changes register, or whose sentences have a shape unlike the rest of the essay, will check.

The fix is the same method above. Patchwriting is a symptom of working with the source open, not of dishonesty.

What a real paraphrase looks like

The difference is in the structure, not the vocabulary. Compare the second and third rows: both changed most of the words, and only one changed how the sentence is built.

What you may not change

Technical terms with fixed meanings stay as they are. 'Statistical significance', 'zone of proximal development', 'gross domestic product' — replacing these with approximations changes the meaning and is worse than leaving them.

Named concepts, instruments and legal terms are the same. Do not paraphrase 'material contribution' into 'substantial input' in a tort essay.

Numbers and findings must be reported accurately. A paraphrase that softens 'increased by 12%' into 'increased substantially' has lost information and may have overstated it.

Where a phrase is genuinely distinctive and unavoidable, quote it inside your paraphrase. Six words in quotation marks in the middle of your own sentence is normal, precise academic writing.

Paraphrase, summary, quotation

Three different tools and students frequently use the wrong one. A paraphrase restates one passage at similar length. A summary compresses a longer argument into much less space. A quotation reproduces exact words.

Use a summary for the shape of a study or an argument — a sentence covering a whole paper. Use a paraphrase for a specific claim you are going to work with. Use a quotation only when the exact words matter: contested phrasing, a definition, a statutory text, or language you are analysing.

All three need citations. A summary of a whole book still credits the book, and the frequency of citation is the only thing that changes.

Paraphrasing tools and AI rewriters

Tools that reword text are, in effect, automated patchwriting. They work sentence by sentence on text they can see, which is precisely the process that produces the problem.

They also introduce errors. Synonym substitution without understanding produces sentences that are technically wrong — a rewriter that turns 'significant' into 'important' has changed a statistical claim into an evaluative one.

Most institutions now treat submitting tool-rewritten text as misconduct, either as plagiarism or under an AI-use policy, and several detection systems flag the characteristic patterns. Check your assessment brief.

There is a legitimate use: reading a tool's version of your own sentence to see whether it was clear. Using it on someone else's text and submitting the result is not that.

How much citing is enough

Cite at the first mention in each paragraph and wherever a reader might otherwise attribute a claim to you. A paragraph drawing on one source needs the citation at the start and, if it is long, again at the end.

Where a whole subsection follows one source, say so — 'the account below follows Ferreira (2024)' — and then cite specific claims. That is clearer than thirty identical brackets and markers prefer it.

The place to over-cite rather than under-cite is a passage close to paraphrase. If a reader could reasonably wonder whose words these are, the citation removes the doubt, and doubt in that direction is what panels examine.

Checking your own draft

Read any paraphrased passage next to the original. If the sentences run in the same order and turn on the same connectives, it is patchwriting whatever the vocabulary looks like.

A more reliable test: cover both and restate the point aloud. If you cannot, you did not understand it well enough to paraphrase it, and the paragraph needs rereading rather than rewording.

Use a similarity report as a diagnostic where you have access to one before submission. A string of six or seven consecutive matching words is worth looking at even when the overall percentage is low.
