Confounded, defeated (6)
I believe the answer is:
undone
This clue is a double definition.
'confounded' is the first definition.
(thesaurus)
'defeated' is the second definition.
(I've seen this in another clue)
(Other definitions for undone that I've seen before include "Not finished; ruined" , "Not finished; untied" , "Ruined - no longer fastened" , "Not bound" , "Reversed" .)
