Pronunciation

  • IPA (Classical): [fɛˈroː.kɪ.taːs][1]
  • IPA (Ecclesiastical): [feˈrɔː.t͡ʃi.tas][1]

Forms

ferōcitās f (genitive ferōcitātis); third declension[1]

Etymology

It is from Latin ferōx (“wild, fierce”) + -tās.[2][1] De Vaan suggests ⟨ferōx⟩ may contain a second element ⟨*-h₃kʷ-⟩ “having a fierce aspect”, added to ferus “wild”, which he traces to Proto-Italic *χwero-, Proto-Indo-European *ǵʰweh₁r- (“wild animal”), cognate with Ancient Greek θήρ (thḗr, “wild beast”).[3]

Earliest recorded meaning

The OLD's earliest citations are Cicero.[2] Köbler dates Cicero 81–43 BC.[4]

Semantic evolution

It meant wild or untamed courage, fierceness, in a good sense high spirit, valour, as in Cicero's animī ferōcitās, and in a bad sense savageness, excessive spirits, aggressiveness, insolence.[2][5][6]

In Ecclesiastical Latin it means untamed courage, fierceness.[7] British Medieval Latin applied it to people, animals and natural forces.[8] English ferocity (c. 1600) is from it through French.[9]

Timeline

  • 81–43 BC – Cicero uses it.[2][4]
  • c. 1600 – English ferocity is recorded.[9]
