Plagiarism is the "wrongful appropriation" and "purloining and publication" of another author's "language, thoughts, ideas, or expressions," and the representation of them as one's own original work.[1][2] The idea remains problematic with unclear definitions and unclear rules.[3][4][5] The modern concept of plagiarism as immoral and originality as an ideal emerged in Europe only in the 18th century, particularly with the Romantic movement.
Plagiarism is considered academic dishonesty and a breach of journalistic ethics. It is subject to sanctions like expulsion.
Plagiarism is not a crime per se but in academia and industry it is a serious ethical offense,[6][7] and cases of plagiarism can constitute copyright infringement.
Etymology[edit]
In the 1st century. the use of the Latin word plagiarius (literally kidnapper), to denote someone stealing someone else's work, was pioneered by Roman poet Martial, who complained that another poet had "kidnapped his verses." This use of the word was introduced into English in 1601 by dramatist Ben Jonson, to describe as a plagiary someone guilty of literary theft.[6][8]
The derived form plagiarism was introduced into English around 1620.[9] The Latin plagiārius, "kidnapper", and plagium, "kidnapping", has the root plaga ("snare", "net"), based on the Indo-European root *-plak, "to weave" (seen for instance in Greek plekein, Bulgarian "плета" pleta, Latinplectere, all meaning "to weave").
Legal aspects[edit]
Although plagiarism in some contexts is considered theft or stealing, the concept does not exist in a legal sense. "Plagiarism" is not mentioned in any current statute, either criminal or civil.[10][7] Some cases may be treated as unfair competition or a violation of the doctrine of moral rights.[7]The
