Etymology
The word "restroom" is a 20th-century American English compound euphemism. Its first element, "rest," draws on the older sense of "refreshment" or "relief from exertion," while "room" simply denotes an enclosed space. The term was coined to provide a polite and indirect reference to a facility for bodily functions, replacing more direct terms. This linguistic strategy of using a pleasant or neutral concept ("rest") to mask a potentially embarrassing one is common in English, seen in similar terms like "bathroom" or "powder room."
Analysis
Structure: rest (to pause, to refresh) + room (an enclosed space)
- rest: From Old English ræst, rest (rest, quiet, repose). In this compound, it functions with the sense of a place for refreshment or relief.
- room: From Old English rūm (space, extent, an enclosed space). In this compound, it functions as the head noun, specifying the type of location.
