Question Western hotel in French (4)
I believe the answer is:
when
'question' is the definition.
'western hotel in french' is the wordplay.
'western' becomes 'w'.
'hotel' becomes 'h' (phonetic alphabet).
'in french' becomes 'en' ('in' in French).
'w'+'h'+'en'='WHEN'
(Other definitions for when that I've seen before include "Over what period?" , "As soon as" , "At what time?" , "stop pouring the drink" , "Say it when you''ve had enough" .)
