Bishop at hotel in West Country city (4)
I believe the answer is:
bath
'west country city' is the definition.
(Bath is a city in the West Country)
'bishop at hotel' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'b'+'at'+'h'='BATH'
'in' acts as a link.
(Other definitions for bath that I've seen before include "Sit in it to wash" , "City in Somerset noted for hot springs" , "City where Persuasion ends" , "English city - tub" , "Stopper for hole (don't let 8 through it!)" .)
