What is plagiarism, what are its types, and how can students avoid it in assignments?

In one line

Plagiarism is presenting someone else's words, ideas, code, data or designs as your own without proper acknowledgement.

Explained simply

If you copy your friend's journal and submit it with your name, everyone agrees that's cheating. Copying paragraphs from a website into your report without credit is the same thing; the 'friend' just happens to be a stranger online.

Technically, plagiarism is an academic and ethical offence of intellectual dishonesty. It applies whether or not the source is copyrighted and whether or not it was intentional. In India, the UGC (Promotion of Academic Integrity and Prevention of Plagiarism in Higher Educational Institutions) Regulations, 2018, set penalties for plagiarism in academic work.

How it works

1. Types:
2. Direct (verbatim): copying text word for word without quotation marks and citation.
3. Paraphrasing plagiarism: rewording someone's idea without credit.
4. Mosaic (patchwriting): mixing copied phrases from several sources with a few of your own words.
5. Self-plagiarism: reusing your own earlier submitted or published work without permission or disclosure.
6. Code and data plagiarism: copying programs, datasets, figures or designs without credit.
7. Accidental plagiarism: forgetting to cite, or citing incorrectly.
8. How to avoid: take notes with sources; use quotation marks for exact words; paraphrase genuinely (change structure and words) and still cite; cite using a consistent style (e.g. IEEE, APA); list references; use plagiarism-checking tools before submission; start assignments early.

Quick example

Original (from a textbook): 'Communication is complete only when the receiver understands the message as intended.' Plagiarised: 'Communication is complete only when the receiver understands the message as intended.' (no quotes, no credit). Acceptable quote: 'Communication is complete only when the receiver understands the message as intended' [1]. Acceptable paraphrase: The process succeeds only if the receiver interprets the message the way the sender meant it [1].

Common mistakes

• Thinking changing a few words removes plagiarism; the idea still needs credit.
• Believing that internet content is free to copy without citation.
• Confusing plagiarism (ethical/academic) with copyright infringement (legal).

How MU asks it

Asked as 'What is plagiarism? How can it be avoided?' (4 to 5 marks) or 'Differentiate between plagiarism and copyright infringement' (5 marks). Define plagiarism, list four or five types with one-line explanations, and give practical avoidance methods. Mentioning the UGC 2018 regulations adds value.
