Plagiarism

The appropriation of another person's ideas, processes, results, or words without giving appropriate credit. A passage or idea counts as plagiarised if a reasonable reader would attribute it to the new author when the substance originated with someone else.

Editorial commentary

Plagiarism spans a spectrum from verbatim copying of text without quotation marks or citation, through paraphrasing without attribution (mosaic plagiarism), to misappropriation of unpublished ideas encountered in peer review or grant review. It is distinct from copyright infringement (a legal concept) and from self-plagiarism (which involves one's own prior work). COPE flowcharts provide standard editorial responses depending on the extent and intentionality.
