Meaning
In British English, loo is an informal everyday word for a toilet or toilet room.
How it is used
Cambridge Dictionary labels loo as UK English and informal for toilet. Collins independently defines it as a British informal word for a toilet or lavatory. It is common in relaxed everyday speech and is generally milder and more neutral in Britain than some stronger slang alternatives.
Examples
- “Excuse me, where's the loo?”
- “I'll just go to the loo before we leave.”
- “Are there any public loos near the station?”
Pronunciation
/luː/ · LOO
Tone and register
Informal but ordinary and widely understood in Britain. Loo is generally suitable for casual conversation, though toilet is clearer in formal signs, accessibility information, and official instructions.
Visitor guidance
Visitors can safely understand Where's the loo? as a request for the toilet. In formal or accessibility-sensitive contexts, toilet, accessible toilet, or the wording used by the venue may be clearer. Do not assume loo refers only to the fixture itself; in conversation it can mean the room or facilities more broadly.
Cultural context
Loo is useful visitor vocabulary because it appears frequently in British speech, informal writing, and phrases such as loo roll or public loos. The word is regional in register rather than uniquely London-specific, and British speakers also use toilet and other alternatives depending on context.
