Superwoman out in States (8)
I believe the answer is:
titaness
'superwoman' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see an association between them that I don't see?
'out in states' is the wordplay.
'out' indicates anagramming the letters.
'in'+'states'='instates'
'instates' is an anagram of 'TITANESS'.
Can you help me to learn more?
(Other definitions for titaness that I've seen before include "Phoebe, say" , "ogre" , "Giant goddess" , "immortal" , "big girl" .)
