Pronunciation

  • Classical: [feːˈliː.kɪ.taːs][1]
  • Ecclesiastical: [feˈliː.t͡ʃi.tas][1]

Forms

fēlīcitās f (genitive fēlīcitātis); third declension[1]

Etymology

It is formed from Latin fēlīx (“fruitful; fortunate”) + -tās.[2][1][3] De Vaan traces fēlīx to Proto-Italic *fēl(w)ī- (“suckling”) and Proto-Indo-European *dʰeh₁-l(u)-i-, from the root Proto-Indo-European *dʰeh₁- (“to suck, nurse”); its sense developed from “suckling, with young” to “fruitful” and “fortunate”.[3] The same root is in fēmina (“woman”) and fīlius (“son”).[3]

Earliest recorded meaning

De Vaan dates it from Terence.[3] Köbler first records it in Columella.[4]

Semantic evolution

Fēlīcitās is “good fortune, luck” (Cicero of Sulla's cōnsilium, imperium et fēlīcitās), personified as a goddess, and of a person who is a city's good fortune.[2][5][1] It is success, prosperity, and in philosophy true happiness, blessedness.[2][1] From the first century AD it is also a happy gift (a fine memory), the fertility of land, and the aptness of a writer's style, as in Petronius' Horātiī cūriōsa fēlīcitās, “the studied felicity of Horace”.[2][5]

Church Latin glosses it “felicity”,[6] and medieval Latin uses it for the bliss of heaven.[7] English felicity comes from it through Old French in the late 14th century.[8]
