To avoid plagiarism, credit every source whose words, ideas or data you use: quote exact words in quotation marks, paraphrase genuinely in your own words, and cite both. Plagiarism is presenting someone else's work as your own.
Academic writing is built on other people's work, and using it is expected. The problem arises only when the line between their work and yours is hidden. This guide shows how to keep that line clear.
Avoiding Plagiarism in Five Habits
- Mark every note as a quotation, a paraphrase or your own idea, with the source.
- Put exact words in quotation marks and cite them, with a page number.
- Paraphrase from memory, then check against the source and cite it.
- Build your reference list as you research, not at the end.
- Follow your course's rules on reusing work and using AI tools.
What Counts as Plagiarism
Plagiarism is about more than copied sentences. Presenting an author's distinctive argument, data or even the structure of their analysis as your own original thinking is plagiarism, even if no sentence matches.
Universities treat it seriously because it undermines the purpose of assessment: showing what you can do. Penalties range from a reduced or zero mark to failing a module and, in serious or repeated cases, suspension or expulsion.
The Five Types of Plagiarism
| Type | What it looks like | How to avoid it |
|---|---|---|
| Direct | Copying exact words without quotation marks and a citation | Quote and cite, or paraphrase properly |
| Mosaic or patchwriting | Swapping words for synonyms while keeping the source's structure | Write from the idea, not the sentence |
| Paraphrase without citation | Rewording an idea but not crediting it | Cite every borrowed idea |
| Self-plagiarism | Reusing your own submitted work without permission | Ask your tutor before reusing material |
| Contract cheating | Submitting work someone else wrote as your own | Use outside help only for study and reference |
Most students who break the rules do so through the subtler forms, especially patchwriting and uncited paraphrase, rather than outright copying.
Quoting Properly
Quote when the exact words matter: a precise definition, a memorable phrase or a claim you want to represent in its author's terms. A proper quotation does two things: it encloses the words in quotation marks and it carries a citation, usually with a page number.
APA 7th example: Dweck (2006) describes a growth mindset as "the belief that your basic qualities are things you can cultivate through your efforts" (p. 7).
Keep quotations short and use them sparingly. Most of your engagement with sources should be paraphrase and analysis.
Paraphrasing Properly
A paraphrase restates a source's idea in your own words and your own sentence structure. Done well, it shows you understood the idea. It still needs a citation, because the idea is not yours.
Original: "Students who believe intelligence can be developed tend to persist longer when they face difficult problems."
Patchwriting (plagiarism): Students who think intelligence can be grown usually keep going longer when they encounter hard problems (Author, 2020).
Genuine paraphrase: According to Author (2020), persistence on challenging tasks is linked to whether learners see ability as something that improves with effort.
The patchwritten version keeps the original's structure and swaps synonyms, so it is plagiarism even with a citation. The genuine paraphrase rebuilds the idea from scratch.
A reliable test: close the source, write the idea from memory, then reopen the source to check accuracy. If your version mirrors the original sentence, start again.
What You Do Not Need to Cite
Common knowledge does not need a citation: facts that are widely known, undisputed and easy to check, such as water boiling at 100°C at sea level or the Second World War ending in 1945.
What counts as common knowledge depends on your audience and field. A fact familiar to specialists may still need a citation for a general reader. Statistics, interpretations and specific findings always need one. If in doubt, cite.
Similarity Scores and Turnitin
Many institutions run submissions through text-matching software such as Turnitin, which compares your work with a large database and produces a similarity score. The score shows how much text matches other sources; it is not a plagiarism verdict.
- Matches to properly quoted and cited material are normal.
- Reference lists and common phrases often match.
- What matters is whether each matched passage is quoted and cited correctly.
- There is no universal "safe" percentage; tutors read the report, not just the number.
AI Tools and Academic Integrity
Rules on generative AI vary sharply between institutions and even between modules. Some ban it, some allow limited uses such as brainstorming or proofreading, and some require you to declare any use.
Check your course's policy before using any AI tool. Never present AI-generated text as your own where that is not allowed, and verify every reference an AI tool suggests: they can invent sources that do not exist.
Habits That Prevent Plagiarism
- Careful notes: mark quotations, paraphrases and your own thoughts differently, each with the source and page.
- Running references: add each source to your reference list when you first use it.
- Enough time: most accidental plagiarism happens when deadlines force shortcuts.
- A final check: match every in-text citation to the reference list before submitting.
- Ask when unsure: tutors and academic skills services would rather answer a question than handle a misconduct case.
How EssayDonkey Helps You Avoid Plagiarism
Send your draft and citation style. An editor checks that quotations are marked and cited, paraphrases are genuine and credited, and every in-text citation matches the reference list. Changes are tracked so you can learn from each one.
Any custom paper we write is written from scratch, plagiarism-checked and meant for study and reference. Submitting it as your own work would itself be plagiarism.

Frequently Asked Questions
Presenting someone else's words, ideas, data or structure as your own without proper credit. It includes copying, uncited paraphrase, patchwriting, reusing your own past work and submitting work you did not write.
Citing is necessary but not always enough. You must also put exact words in quotation marks and genuinely reword paraphrases.
There is no universal threshold. What matters is whether matched passages are properly quoted and cited.
Yes, at most institutions. Reusing work you submitted before needs your tutor's permission.
No, but what counts as common knowledge depends on your field and audience. If in doubt, cite.
Only if your course allows it, and you still need to cite the original source. Check the policy first.
