Pronunciation

  • IPA: UK /ˈbɑːθ.ruːm/, /ˈbɑːθ.rʊm/, US /ˈbæθ.ruːm/[1]

Etymology

It is a compound, from English bath + room,[2][3] also written bath-room.[2]

Earliest recorded meaning

A room with apparatus for bathing: 1780 in Etymonline and the OED.[2][3] MWU gives 1670 as its first known use.[4]

Semantic evolution

It first meant only a room for bathing, the sole definition in the Century Dictionary of 1902.[2] In the 20th century it came to be used in the United States as a euphemism for a room with a toilet, a use that often confuses British visitors.[2][5] Go to the bathroom, to relieve oneself, is from 1920, in a children's book, and is used whether or not a real bathroom is involved.[2]
