Pronunciation

  • Classical: [frau̯.dʊˈɫɛn.tʊs][1]
  • Ecclesiastical: [frau̯.duˈlɛn.tus][1]

Forms

fraudulentus (feminine fraudulenta, neuter fraudulentum, adverb fraudulenter); first/second-declension adjective[1]

Etymology

It is from Latin fraus (“deceit, fraud”) + -ulentus.[2][1][3] De Vaan traces fraus to Proto-Italic *frawV- and, with a query, to Proto-Indo-European *dʰrou-V́-d(ʰ)-; he rejects the derivations from Proto-Indo-European *dʰreugʰ- (“to deceive”) as resting on ad hoc assumptions.[4]

Earliest recorded meaning

It is found from Plautus on.[4][5][6] In the Rudens a speaker asks whether anyone has seen a bald, snub-nosed old man, a cheat (fraudulentum),[7] and the Captivi has the superlative: from the best of men they become the worst and most deceitful.[8][3]

Semantic evolution

Cicero calls the Carthaginians deceitful and lying in the speeches on the agrarian law,[7][9] and in the De officiis uses it of fraudulent sales.[7][8] Horace has it of a leader, Gellius of cunning,[3] and Pliny the Elder calls magic the most fraudulent of the arts.[9] The comparative appears first in Tertullian.[8]

In Medieval Latin it was used of people, the devil among them, and of things: forged or false, deceptively like, lying, and in a milder sense sly or shrewd;[10] it is spelled also with ⟨-dol-⟩.[10] In Britain Aldhelm and Bede use it,[11] also as a noun for a dishonest person.[11] Italian has it as fraudolento.[9]
