A southern pro with E is a goddess! (7)
I believe the answer is:
astarte
'goddess' is the definition.
(I've seen this before)
'a southern pro with e' is the wordplay.
'southern pro' becomes 'start' (I am not sure about this - if you are sure you should believe this answer much more).
'with' is a charade indicator (letters next to each other).
'a'+'start'+'e'='ASTARTE'
'is a' acts as a link.
Can you help me to learn more?
(Other definitions for astarte that I've seen before include "Pagan deity" , "Phoenician love goddess" , "She might have helped with fertility problems" , "Mediterranean goddess" , "Ancient goddess" .)
