chastity (n.) Look up chastity at Dictionary.com
c. 1200, chastete, "sexual purity" (as defined by the Church), including but not limited to virginity or celibacy, from Old French chastete "chastity, purity" (12c., Modern French chasteté), from Latin castitatem (nominative castitas) "purity, chastity" from castus (see caste).
Chastity is merely a social law created to encourage the alliances that most promote the permanent welfare of the race, and to maintain woman in a social position which it is thought advisable she should hold. ["Saturday Review," Aug. 10, 1867, quoted in Lecky, "European Morals," 1869]
