Forsaken (9)
I believe the answer is:
abandoned
'forsaken' is the definition.
('abandon' can be a synonym of 'forsake')
This is all the clue.
(Other definitions for abandoned that I've seen before include "Derelict, deserted" , "marooned" , "Given up?" , "Profligate - gave up - left" , "lacking in self-control" .)
