Abandoned, deserted (8)
I believe the answer is:
forsaken
I believe this clue is a double definition.
'abandoned' is the first definition.
(similar in meaning)
'deserted' is the second definition.
('forsake' can be a synonym of 'desert')
(Other definitions for forsaken that I've seen before include "Left abandoned and deserted" , "Abandoned; renounced" , "Helpless" .)
