Think about West Country heroine (6,5)
I believe the answer is:
wonder woman
'heroine' is the definition.
(female superhero)
'think about west country' is the wordplay.
'think about' becomes 'wonder' (to wonder about something is to contemplate it).
'west' becomes 'W' (abbreviation).
'country' becomes 'oman' (Oman is an example).
'wonder'+'w'+'oman'='WONDER WOMAN'
(Other definitions for wonder woman that I've seen before include "Extraordinary female" , "US comic heroine" .)
