Pronunciation

  • IPA (Ecclesiastical): [ˈplaː.d͡ʒi.um][1]

Forms

plagium n (genitive plagiī or plagī); second declension[1]

Etymology

It is from plaga “hunting net” with the suffix -ium, so originally “a catching”.[2][1][3] Wiktionary traces ⟨plaga⟩ to Proto-Indo-European *pleḱ- (“to weave”), as in plectō.[1]

Earliest recorded meaning

Köbler's first source is Varro, whom he dates 116–27 BC.[3] The OLD's citation for netting game is from Grattius.[2]

Semantic evolution

It meant the netting of game, as in Grattius, and in law, as in Ulpian, kidnapping, the crime of stealing or selling a free man or another's slave.[2][4]

Medieval Latin used it for the crime of enslaving a free man or harbouring another's runaway slave.[4] British Medieval Latin used it for kidnapping, as in Alexander Neckam.[5] It survives in Italian and Spanish plagio “plagiarism”.[1] Its derivative plagiārius “kidnapper”, used by Martial of a literary thief, gave plagiary and English plagiarism.[6]

Timeline

  • 116–27 BC – Varro uses it.[3]
  • before 223 AD – Ulpian uses it of kidnapping.[2][3]
  • 1620s – English plagiarism is recorded.[6]
