Plagiarism Etymology

English Plagiarism (1615–25), earlier plagiary (1590–1600), derives from Latin plagiārius, "kidnapper", equivalent to plagium, "kidnapping", which contains Latin plaga ("snare", "net"), based on the Indo-European root *-plak, "to weave" (seen for instance in Greek plekein, Latinplectere, both meaning "to weave").
