Pronunciation

  • Classical: [ˈkas.tɪ.taːs][1]
  • Ecclesiastical: [ˈkas.ti.tas][1]

Forms

castitās f (genitive castitātis); third declension[1]

Etymology

It is from Latin castus (“pure, chaste”) + -tās.[2][1][3] Etymonline glosses castus as “cut off, separated; pure”.[4]

Earliest recorded meaning

Cicero has it first,[5] in the De legibus, saying that women should understand that their nature can bear complete chastity.[2][6]

Semantic evolution

Lewis & Short call the sense “chastity” rare but classical, with pudīcitia as its synonym.[6] Horace uses it of a wife's fidelity, and Valerius Maximus of a son of doubtful chastity.[2] Vitruvius uses it of moral integrity, saying that no work can be done without good faith and integrity,[2] and Gellius of purity of life and of the ceremonial purity required to enter temples.[6][2] The grammarian Nonius says it is more than pudīcitia, since it adds religious cleanness.[3] It has no plural.[3] Church Latin uses it for chastity and purity.[7] Through Old French it gave English chastity about 1200.[4]
