  1. Scots · derived fromgardyloo
  2. French · derived froml'
  3. English todayloo

Uncertain, although usually derived in some way from Waterloo, the site of Wellington's 1815 victory over Napoleon, likely via a pun based on water closet. Other suggested derivations include corruptions of French l'eau (“water”), lieu (“place”), lieux d'aisances (“'places of convenience': a lavatory”), lieu à l'anglaise (“'English place': a British-style lavatory”), bordalou (“a diminutive chamber pot”) or gardez l'eau (“'mind the water'”), via Scots gardyloo, formerly used in Edinburgh while emptying chamber pots out of windows; the supposed use of "Room 100" as the lavatory in Continental hotels; a popularisation of lew, a regional corruption of lee (“downwind”), in reference to shepherds' privies or the former use of beakheads on that side of the ship for urination and defecation; or a clipped form of the name of the unpopular 19th-century Countess of Lichfield Lady Harriett Georgiana Louisa Hamilton Anson, who was the subject of an 1867 prank whereby her bedroom's name-card was placed on the door to the lavatory, prompting the other guests to begin speaking of "going to Lady Louisa".
