Wrong a young woman (5)
I believe the answer is:
amiss
'wrong' is the definition.
('amiss' can be a synonym of 'wrong')
'a young woman' is the wordplay.
'young woman' becomes 'miss' ('miss' can be a synonym of 'young woman').
'a'+'miss'='AMISS'
(Other definitions for amiss that I've seen before include "Taking wrong turn" , "Not quite right" , "Mistakenly" , "Out of order" , "Not functioning properly" .)
