Plagiarism

A demonstration of how an individual may replicate text from another source to intentionally deceive a reader into believing they wrote the text themselves. In this example, the introductory paragraph of the Wikipedia article for the Trojan War (top) has been copy-and-pasted into a Microsoft Word document by John Doe (bottom). Doe, who is writing an essay about the Trojan War, has therefore committed plagiarism by attempting to pass off the writing as his own, without presentation as a quote, and without sourcing to the original article.

Plagiarism is the representation of another person's language, thoughts, ideas, or expressions as one's own original work.^[1][2][3] Although precise definitions vary depending on the institution,^[4] in many countries and cultures plagiarism is considered a violation of academic integrity and journalistic ethics, as well as of social norms around learning, teaching, research, fairness, respect, and responsibility.^[5] As such, a person or entity that is determined to have committed plagiarism is often subject to various punishments or sanctions, such as suspension, expulsion from school^[6] or work,^[7] fines,^[8][9] imprisonment,^[10][11] and other penalties.

Not all cultures and countries hold the same beliefs about personal ownership of language or ideas, and plagiarism is typically not in itself a crime. However, like counterfeiting, fraud can be punished in a court^[12][13] for prejudices caused by copyright infringement,^[14][15] violation of moral rights,^[16] or torts. In academia and in industry, it is a serious ethical offense.^[17][18] Plagiarism and copyright infringement overlap to a considerable extent, but they are not equivalent concepts,^[19] and although many types of plagiarism may not meet the legal requirements in copyright law as adjudicated by courts, they still constitute the passing-off of another's work as one's own, and thus plagiarism.
