Forms
īrācundia f (genitive īrācundiae); first declension[1]
Etymology
It is formed from Latin īrācundus (“irascible”) + -ia.[2][1] The adjective comes from īra (“anger”) with a suffix ⟨-cundus⟩ taken from other adjectives; de Vaan traces ⟨īra⟩ to Proto-Indo-European *h₁eysh₂- (“anger”), cognate with Ancient Greek οἶμα (oîma, “rush, spring”).[3]
Earliest recorded meaning
De Vaan gives Plautus as its first author.[3] In the Curculio a man says he goes about angry with no moderate īrācundia.[2]
Semantic evolution
It is a proneness to anger, hot temper: in Terence Demea is told to drop his irascibility and be cheerful at his son's wedding.[2] It is also anger itself, passion or resentment, as in Plautus.[2] Cicero sets it among the lasting dispositions of the mind, as anxiety is in some people, irascibility in others.[4] Church Latin glosses it “wrath, anger”.[5]
Timeline
- c. 250–184 BC – Plautus of anger.[3][2][6]
- 190–159 BC – Terence of a hot temper.[2][6]
- 81–43 BC – Cicero of irascibility as a disposition.[4][6]
