- latrine
- c.1300, from L. latrina, contraction of lavatrina "washbasin, washroom," from lavatus, pp. of lavare "to wash" (see lave) + -trina, suffix denoting "workplace." Its reappearance in 1640s is probably a re-borrowing from Fr.; esp. of a privy of a camp, barracks, college, hospital, etc. Latrine rumor "baseless gossip" (of the kind that spreads in conversations in latrines) is military slang, first recorded 1918.
