Origin: Latin caelibātus
Origin: , from caelebs, caelib-, unmarried. Usage Note: Historically, celibate means only “unmarried”; its use to mean “abstaining from sexual intercourse” is a 20th-century development. But the new sense of the word seems to have displaced the old, and the use of celibate to mean “unmarried” is now almost sure to invite misinterpretation in other than narrowly ecclesiastical contexts. Sixty-eight percent of the Usage Panel rejected the older use in the sentence He remained celibate [unmarried], although he engaged in sexual intercourse.
