Fancy nice women including a man-hater! (5)
I believe the answer is:
cynic
'a man-hater' is the definition.
(thesaurus)
'fancy nice women including' is the wordplay.
'including' indicates a hidden word.
'CYNIC' is hidden within 'fancy nice women'.
(Other definitions for cynic that I've seen before include "Scoffer" , "One thinking the worst" , "One who questions the worth of anything" , "Fault-finder" , "Pessimistic viewer of human motives" .)
