West Country female (5)
I believe the answer is:
woman
'female' is the definition.
(I know that woman is a type of female)
'west country' is the wordplay.
'west' becomes 'W' (abbreviation).
'country' becomes 'oman' (Oman is an example).
'w'+'oman'='WOMAN'
(Other definitions for woman that I've seen before include "Mature female" , "With 1a [NEW] a freedom fighter" , "Adult female" , "Lady" , "See 16" .)
