Tragic woman, person in opposition no more (8)
I believe the answer is:
antigone
'tragic woman' is the definition.
(character from Sophocles tragedy)
'person in opposition no more' is the wordplay.
'person in opposition' becomes 'anti'.
'no more' becomes 'gone'.
'anti'+'gone'='ANTIGONE'
(Other definitions for antigone that I've seen before include "Jocasta's daughter" , "Make drama" , "The Burial at Thebes is Heaney's translation of Sophocle's (8)" , "classical play" , "Greek play" .)
