City club for one if female (7)
I believe the answer is:
cardiff
'city' is the definition.
(Cardiff is an example)
'club for one if female' is the wordplay.
'club for one' becomes 'card' (clubs is a playing card suit).
'female' becomes 'f' (common abbreviation).
'card'+'if'+'f'='CARDIFF'
(Other definitions for cardiff that I've seen before include "Capital on the Taff" , "Capital of Wales" , "Place in Wales" , "Welsh city" , "Welsh capital" .)
