Pronunciation

  • Classical: [kae̯.lɪˈbaː.tʊs][1]
  • Ecclesiastical: [t͡ʃe.liˈbaː.tus][1]

Forms

caelibātus m (genitive caelibātūs); fourth declension[1]

Etymology

It is formed from Latin caelebs (“unmarried”) + -ātus.[2][1][3] The origin of caelebs itself is uncertain: de Vaan finds a good alternative to the older reconstructions in the European word Proto-Indo-European *keh₂i-lo- (“whole”), through a noun for “wholeness” that may have come to mean “unboundness, celibacy”; the origin of its ⟨-b-⟩ remains unclear.[4]

Earliest recorded meaning

Its first record is in Seneca's De beneficiis,[2][4] meaning the state of being unmarried, celibacy.[2][5]

Semantic evolution

Lewis & Short note that the word is post-Augustan and that single life was severely punished by the Julian and Papian-Poppaean laws.[5] Suetonius uses it of men reproached for not marrying, and the jurist Gaius uses it in a legal sense.[2] Georges sets it against viduitas, the state of a widow.[6]

Christian writers gave it a religious value: Fulgentius equates it with virginal abstinence,[3] and medieval authors from Aldhelm on use it for virginity and the unmarried life.[7][8] English celibate was first a noun for this state (1610s), borrowed from French célibat.[9]

Timeline

  • 4 BC–AD 65 – Seneca uses it for the unmarried state.[2][10]
  • c. 75–c. 150 AD – Suetonius uses it of men reproached for remaining single.[2][10]
  • 140–180 AD – The jurist Gaius uses it in his Institutes.[2][10]
  • 639–709 AD – Aldhelm links it with virginity.[7][10]
  • 1610s – English borrows celibate through French.[9]

Meanings

Noun

  1. The state of not being married, single life, celibacy.[2][5]
  2. (Ecclesiastical and Medieval Latin) virginity, a life without marriage chosen for religious reasons.[8][7][11]

Usage notes

Georges and Gaffiot record a separate caelibātus “heavenly life, the life of the gods”, formed from caelum2, found only in Iulius Valerius (4th century AD).[6][12][10]
