Derivation
First attested

Ultimate origin
Proto-Indo-European (*deh₃-)

Pronunciation

  • Classical: [ˈproː.dɪ.tɔr][1]
  • Ecclesiastical: [ˈprɔː.di.tor][1]

Forms

prōditor m (genitive prōditōris); third declension[1]

Etymology

It is formed from prōdō (“to betray, give up”) with the agent suffix -tor.[2][3][1] The verb is formed from prō- (“forth”) and dō (“to give”), which de Vaan derives from Proto-Indo-European *deh₃- (“to give”).[1][4]

Earliest recorded meaning

Köbler gives Plautus as its first author.[5]

Semantic evolution

It is a betrayer or traitor, as Cicero's senate that had “no leaders, and traitors instead of leaders”, and prōditor patriae, a traitor to one's country.[2][6] The TLL treats the feminine prōditrīx with it.[3]

Church Latin glosses it “betrayer, traitor”, and in medieval Latin it is also a scoundrel.[7][8]

Timeline

  • c. 250–184 BC – Plautus.[5]
  • 81–43 BC – Cicero of traitors instead of leaders.[6][5]
