Forms
īra f (genitive īrae); first declension[1] Plautus has the spelling eira, and Lucretius the genitive īrāī.[2][3]
Etymology
It is inherited from Proto-Italic *eisā (“anger”), inherited from Proto-Indo-European *h₁eis-h₂- (“anger”), from the root *h₁eys- (“to set in motion, impel”).[4][1][2][5] The spelling ⟨eira⟩ in Plautus, in a pun on era “mistress”, may reflect an archaic pronunciation with ⟨ē⟩ from ⟨*ei⟩.[4]
Cognate with Avestan aēšma- (“wrath”), Ancient Greek οἶμα (oîma, “rush, swoop”) and οἶστρος (oîstros, “gadfly, frenzy”), Old Norse eisa (“inrush”), Lithuanian aistrà (“violent passion”) and Sanskrit इष् (íṣ-, “refreshment, strength”).[4][2][1]
Earliest recorded meaning
It is found from Naevius on;[4] Plautus writes nē quid in tē malī faxit īra percita, “lest in her roused anger she do you some harm”.[2]
Semantic evolution
Īra is anger, rage and indignation, and in the plural (īrae inter …) bad blood between people.[2] It is also the violence of natural forces (īram caelīque marisque “the rage of sky and sea”).[2] In Church Latin it is the wrath of God and eternal punishment.[6]
English ire, recorded from about 1300, comes from it through Old French ire.[7]
