How to avoid plagiarism.
By the EssayMate team · Updated November 4, 2026
Plagiarism is presenting someone else's words or ideas as your own. Most cases aren't deliberate; they come from rushed notes, weak paraphrasing or forgotten citations. The habits below prevent almost all of them.
Kinds of plagiarism
| Kind | What it looks like |
|---|---|
| Direct | Copying words without quotation marks or a citation. |
| Patchwriting (mosaic) | Mixing a source's phrases with your own, or swapping a few words, without quoting. |
| Paraphrase without citation | Rewriting an idea in your words but not saying where it came from. |
| Self-plagiarism | Reusing your own earlier work without permission. |
| Source misuse | Citing a source for something it doesn't say, or inventing a reference. |
| Undisclosed AI text | Submitting AI-generated text as your own where your course doesn't allow it, or without the required disclosure. |
Eight habits that prevent it
- Take notes in two colours (or with labels): exact quotations in one, your own summary in another, each with the source and page.
- Record every source's details when you first use it, not at the end.
- Quote exactly when the wording matters, with quotation marks and a citation.
- Paraphrase from memory: read the passage, close it, write the idea in your own structure and words, then check and cite.
- Cite ideas, not just words: a paraphrase or a statistic needs a citation too.
- Don't cite what you haven't read: check that each source says what you cite it for.
- Follow your course's AI policy and disclose AI help where required (see how to cite ChatGPT).
- Leave time: most accidental plagiarism happens the night before the deadline.
Paraphrasing: right and wrong
"Students who were not using their mobile phones wrote down more information from the lecture, took more detailed notes, and were able to recall more information from the lecture."
Students who were not on their phones wrote more information from the lecture, took more detailed notes and could recall more of the lecture (Author, Year).
Leaving phones alone during a lecture paid off in two ways: students' notes were fuller, and they remembered more of the content afterwards (Author, Year).
The patchwriting keeps the source's structure and most of its words; even with a citation, it is too close. The paraphrase changes both the structure and the wording, and still cites the source.
Cite in the style your course uses
Every quotation and paraphrase needs an in-text citation and an entry in your reference list, in APA, MLA, Chicago, Harvard or IEEE. Common knowledge (facts widely known and easily checked, such as that Nairobi is Kenya's capital) doesn't need one; when in doubt, cite.
Checking your work
- Read your draft beside your notes and check that every borrowed idea is cited.
- Check each quotation against the source, word for word.
- Check that your reference list matches your in-text citations.
- If your institution offers a similarity check, use it as a guide: a high match on quotations is fine; matches on your own sentences need fixing.
Frequently asked questions
Is paraphrasing without citing plagiarism?
Yes. Ideas need a citation even when the words are your own.
Is using AI plagiarism?
It depends on your course's rules. Submitting AI-generated text as your own where it isn't allowed, or without the required disclosure, is usually treated as academic misconduct. Citing or disclosing AI use as your instructor asks is not.
How many words in a row count as plagiarism?
There's no safe number. Any distinctive phrase taken from a source should be in quotation marks and cited.
