The female’s a goddess (4)
I believe the answer is:
hera
'goddess' is the definition.
(thesaurus)
'the female's a' is the wordplay.
'the female' becomes 'her' (I've seen this before**).
'her'+'a'='HERA'
(Other definitions for hera that I've seen before include "Greek queen of Olympian gods" , "Divinity" , "Jealous sister and wife of Zeus" , "Consort of Zeus" , "marriage goddess" .)
