Top 7 Tried and Tested Paraphrasing Techniques

Key Takeaways:

• Paraphrasing means changing both the words and the sentence structure of a source, not just swapping in synonyms.
• Paraphrased ideas almost always need a citation; only common knowledge is exempt.
• Patchwriting, keeping the original sentence structure while changing a few words, is treated as plagiarism by most journals and universities.
• AI paraphrasing tools can help, but researchers must still verify accuracy, meaning, and originality before submission.

Why Paraphrasing Matters for Researchers

Paraphrasing lets researchers use existing evidence and arguments while writing in their own voice. It is used in literature reviews, discussion sections, and grant proposals. Done well, it improves readability and shows genuine understanding of the source material. Done poorly, it can slide into patchwriting or plagiarism, both of which carry real consequences for publication and academic standing.

What Is Paraphrasing and Why Does It Matter in Research Writing?

Paraphrasing is restating a source’s idea in new words and a new sentence structure while keeping the original meaning. It matters because journals and universities check manuscripts for originality, and weak paraphrasing can be flagged as plagiarism even without intent to copy.

Good paraphrasing also demonstrates that the writer has understood the source deeply enough to explain it independently, rather than simply relocating someone else’s sentence into a new document.

Paraphrasing vs Summarizing vs Quoting: What Is the Difference?

Paraphrasing rewrites a passage in full using your own words and structure, summarizing shrinks a longer passage down to its main point, and quoting reproduces the source’s exact wording in quotation marks. Each has a different use case in research writing, shown below.

The 7 Core Paraphrasing Techniques

These 7 techniques form the foundation of effective paraphrasing. They work best when combined rather than used one at a time, since relying on a single technique, especially synonym swapping, often produces patchwriting instead of a genuine paraphrase.

Technique 1: Read and Digest the Original Passage

Read the source passage 2-3 times, then set it aside and pretend to explain it to a friend via text, IM, or email. This forces the sentence structure to change naturally because you are recalling the concept, not copying the sentence pattern in front of you.

Technique 2: Use Synonyms Carefully

Replace non-technical words with accurate synonyms, but keep field-specific terminology unchanged, since forcing a synonym for a technical term can distort the meaning. Synonym substitution alone is not enough; it must be paired with structural changes.

Technique 3: Change the Word Form

Convert nouns to verbs, adjectives to adverbs, or active constructions to different grammatical forms. For example, an increase in temperature can become the temperature increased, which changes both the grammar and the rhythm of the sentence.

Technique 4: Switch Between Active and Passive Voice

If the original sentence is active, rewrite it in passive voice, and vice versa. This single change often reorders the subject, verb, and object, breaking the original sentence pattern in a way synonym swaps cannot.

Technique 5: Change the Sentence Length and Order

Split one long sentence into 2 shorter ones, or combine 2 short sentences into 1. Also try reordering clauses, for instance stating the result before the method instead of after it, to further distance the paraphrase from the source structure.

Technique 6: Write Your Own Definition

When paraphrasing a definition or concept, explain it as you would to a colleague, using your own framing and examples rather than mirroring the source’s explanation style.

Technique 7: Vary In-Text Citation Phrasing

Rotate citation phrasing across a document: as shown by, according to, researchers found that, and similar variations. This avoids repetitive attribution language while still crediting every source consistently.

Technique 8: Add Your Own Insights Where Feasible

Add your own evaluation or critical opinion of the original study. This will naturally break up the amount of “similar text” that appears together.

Example

• Original: Our findings showed that adolescents from low-income families were more likely to experience increases in social stress in middle school.
• Paraphrased: Interestingly, in a survey spanning 4 school districts, Roseworth and Brighston (2024) found a moderate correlation between family socioeconomic status and scores on the Ellsworthy Social Stress Inventory among adolescents. However, this tool has been validated only in adult populations (Patel et al., 2023), and Roseworth and Brighston could not collect data on parental mental health, which Harksinger et al. (2020) found to be a strong predictor of social stress in preteens and teenagers. Therefore, we build on the work of Roseworth and Brighston (2024) by ….

What Is Patchwriting and How Can You Avoid It?

Patchwriting is a paraphrase that keeps the original sentence structure and word order while only swapping a few words for synonyms. It reads as original but is treated as plagiarism by most journals because the underlying structure was copied, not created.

To avoid it, combine at least 2 of the 7 techniques above for every paraphrased sentence, and always check your version against the source line by line before submission.

• Warning sign: your paraphrase follows the same clause order as the original.
• Warning sign: only adjectives and adverbs have changed, not the sentence’s backbone.
• Fix: rewrite from memory instead of editing the original sentence directly.

When Does Paraphrased Content Still Need a Citation?

Paraphrased content needs a citation whenever the underlying idea, data, or argument came from someone else’s work, even though the wording is entirely your own. Only common knowledge, facts a general audience already accepts, can be paraphrased without a citation.

• Cite: a specific finding, statistic, theory, or argument from a study.
• Cite: a definition coined or refined by a specific author.
• No citation needed: widely accepted facts, such as water boiling at 100 degrees Celsius at sea level.

Citation Styles for Paraphrased Content

Different disciplines expect different citation formats for paraphrased material. The table below summarizes the in-text format for 4 common styles used in research writing.

How Do You Check That a Paraphrase Preserves the Original Meaning?

Compare your paraphrase against the source sentence by sentence and confirm that every number, qualifier, and causal claim still matches. This matters most for technical or statistical content, where a single dropped qualifier such as may or in some cases can change the claim entirely.

• Read your paraphrase aloud without looking at the source; note anything that sounds uncertain.
• Ask a colleague unfamiliar with the source to explain back what your paraphrase says.
• Run the paraphrase through a similarity checker as a secondary, not primary, check.

Can AI Paraphrasing Tools Replace Manual Paraphrasing?

AI paraphrasing tools can speed up drafting, but they cannot fully replace manual paraphrasing because they may distort technical meaning or produce oddly worded, over-paraphrased text.

Researchers who use these tools should treat the output as a first draft, then manually verify accuracy against the source and adjust technical terms that the tool may have altered incorrectly.

• Benefit: faster first drafts and fresh phrasing suggestions.
• Risk: technical terms replaced with inaccurate synonyms.
• Risk: over-paraphrased sentences that read as unnatural or unclear.
• Best practice: always fact-check AI output against the original source.

Worked Examples Across Disciplines

The following examples show the same techniques applied in a STEM context and a social science context, since paraphrasing strategies are not limited to any one field.

Climate Science

Original: rising global temperatures are causing polar ice caps to melt at an accelerated rate.

Paraphrase: polar ice is melting faster as global temperatures continue to climb (Lee, 2021)

Sociology

Original: social media use among adolescents has been linked to increased rates of anxiety and depression. Paraphrase: adolescents who spend more time on social media report higher levels of anxiety and depression (Park, 2021).

Common Paraphrasing Mistakes to Avoid

• Relying only on a thesaurus, which produces patchwriting rather than genuine paraphrase.
• Changing so much of the meaning that the paraphrase no longer reflects the source’s claim.
• Forgetting to cite the source because the wording is entirely new.
• Copying sentence order and clause structure while only swapping a few words.
• Leaving out qualifiers such as often or in some cases, which changes the strength of the claim.
• Over-paraphrasing technical terms that should stay consistent for clarity.

Similarity Checkers and Journal Plagiarism Thresholds

Most journals run submitted manuscripts through similarity-checking software such as iThenticate or Turnitin before sending them for peer review. A high similarity score, even from weak paraphrasing rather than direct copying, can result in a manuscript being returned or rejected outright.

Acceptable thresholds vary by journal and field, but scores are commonly expected to stay below 15-20%, excluding references and standard methodology phrasing. Checking your own draft with similar software before submission can catch patchwriting before an editor does.

What Does Research Say About Patchwriting?

Writing researcher Rebecca Moore Howard’s work on patchwriting shows that many student and early-career writers patchwrite not to deceive, but because they have not yet learned to fully digest and reframe source material in their own words. Her research reframes patchwriting as a teachable skill gap rather than only an integrity violation, which is why practicing the 7 techniques above matters more than memorizing a rule against copying.

Frequently Asked Questions

What is the difference between paraphrasing and plagiarism?

Paraphrasing rewrites an idea in new words and structure with a citation; plagiarism presents someone else’s words or ideas as your own, without credit, regardless of how much wording was changed.

How many words should you change when paraphrasing a sentence?

There is no fixed word count. What matters is changing the sentence structure and wording enough that the paraphrase no longer follows the source’s original clause order or phrasing pattern.

Is using an AI paraphrasing tool like Quillbot considered plagiarism?

Not by itself, but output from these tools still needs a citation if the underlying idea came from a source, and researchers should verify the tool has not distorted technical meaning.

Do you need to cite a paraphrased sentence in APA format?

Yes. APA style requires an author-year citation for paraphrased ideas, for example (Singh, 2023), even though none of the original wording is used.

What percentage of similarity is acceptable in Turnitin for a thesis?

Many universities expect an overall similarity score below 15-20%, excluding references and common phrases, though exact thresholds vary by institution and department.

What is patchwriting and why is it considered plagiarism?

Patchwriting is changing only a few words in a sentence while keeping its original structure intact. It is considered plagiarism because the sentence’s core construction, not just its words, was copied.

Can you paraphrase a direct quote instead of quoting it?

Yes, as long as you rewrite both the wording and structure in your own voice and add a citation; simply removing quotation marks without rewording is not an acceptable paraphrase.

How do you paraphrase a research paper without changing its meaning?

Read the passage fully, restate it from memory using different structure and wording, then compare your version against the original line by line to confirm every claim and qualifier still matches.
