The Kidnapping Roots of Plagiarize

If schools wish to impress upon their students how serious an offense plagiarism is, they might start with an explanation of the word’s history. Plagiarize (and plagiarism) comes from the Latin plagiarius “kidnapper.” This word, derived from the Latin plaga (“a net used by hunters to catch game”), extended its meaning in Latin to include a person who stole the words, rather than the children, of another. When plagiarius first entered English in the form plagiary, it kept its original reference to kidnapping, a sense that is now quite obsolete.
