Pronunciation

  • Classical: [au̯ˈdaː.ki.a][1]
  • Ecclesiastical: [au̯ˈdaː.t͡ʃi.a][1]

Forms

audācia f (genitive audāciae); first declension[1]

Etymology

It is formed from Latin audāx (“bold, daring”) + -ia.[2][1] audāx is from audeō (“to dare”),[3] which de Vaan derives from avidus (“greedy”): it first meant “to want very much”, as the relic ⟨sōdēs⟩ “if you please”, from ⟨*sī audēs⟩, shows in Plautus, and later “to dare”.[4]

Earliest recorded meaning

Köbler dates it from Plautus,[3] who speaks of a man quoi nūlla in pectore est audācia, “who has no courage in his heart”.[2]

Semantic evolution

In a good sense audācia is “daring, boldness, confidence”, a bold act, and with a genitive a bold resolve;[2][5] Sallust has Cato say that boldness in wrongdoing is called courage.[2][5] L&S note that it is more often used in a bad sense: “audacity, impudence, recklessness, rashness”, as in Terence's audāciam meretrīcum spectā, “look at the effrontery of these courtesans”, and a piece of impudence (Plautus: quae istaec audāciast?, “what impudence is this?”).[2][5][1] Celsus uses it of the violent conduct of the insane.[2] Of style and words it is boldness, licence (Ovid: sī verbīs audācia dētur, “if words may be allowed some boldness”).[2]

Church Latin glosses it “boldness, bravery, courage, valour”.[6]
