Lady from western country (5)
I believe the answer is:
woman
'lady' is the definition.
(I've seen this before)
'western country' is the wordplay.
'western' becomes 'w'.
'country' becomes 'oman' (Oman is an example).
'w'+'oman'='WOMAN'
'from' acts as a link.
(Other definitions for woman that I've seen before include "Lady" , "Adult female" , "Mature female" , "person not going on stag-night" , "With 1a [OLD], one's rather timid" .)
