A beautiful woman describes Eastern ways (7)
I believe the answer is:
avenues
'ways' is the definition.
(avenue is a kind of way)
'a beautiful woman describes eastern' is the wordplay.
'beautiful woman' becomes 'Venus' (goddess of love).
'describes' means one lot of letters goes inside another (describe can mean to form the outline of).
'eastern' becomes 'e'.
'venus' enclosing 'e' is 'venues'.
'a'+'venues'='AVENUES'
(Other definitions for avenues that I've seen before include "Tree-lined roads" , "City streets or methods of approach" , "Approaches" .)
