Simplified etymology
Loo, meaning “lavatory,” was used by James Joyce and may have existed before the 20th century; Nancy Mitford later introduced it to many readers in her 1940 novel Pigeon Pie. Its origin is uncertain. Perhaps the most plausible proposal connects it with Waterloo, an early 20th-century trade name for iron cisterns. Derivation from the Edinburgh warning gardyloo is popular but unlikely, while a proposed connection with French lieux d’aisances, “places of ease,” is also inconclusive.
Etymology
Of uncertain origin; first attested in the 20th century. Suggested derivations include French lieux d'aisances ('places of ease') or gardyloo (a warning cry when emptying chamber pots), but none is certain.
