Plagiarism

Plagiarism is the representation of another person's language, thoughts, ideas, or expressions as one's own original work. Although precise definitions vary depending on the institution, 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. 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 or work, fines, imprisonment, 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 for prejudices caused by copyright infringement, violation of moral rights, or torts. In academia and in industry, it is a serious ethical offense. Plagiarism and copyright infringement functionally overlap, depending on the copyright law protection in force, but they are not equivalent concepts, 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.

Etymology and ancient history

In the 1st century, the use of the Latin word plagiarius (literally "kidnapper") to denote copying someone else's creative work was pioneered by the Roman poet Martial, who complained that another poet had "kidnapped his verses". Plagiary, a derivative of plagiarus, was introduced into English in 1601 by dramatist Ben Jonson during the Jacobean Era to describe someone guilty of literary theft. The derived form plagiarism was introduced into English around 1620.
