Deprived (of); abandoned (6)
I believe the answer is:
bereft
I believe this is a double definition.
'deprived of' is the first definition.
(thesaurus)
'abandoned' is the second definition.
(I've seen this before)
(Other definitions for bereft that I've seen before include "Deprived, say of reason" , "Sorrowful through loss" , "Having a deep sense of loss" , "Deprived, perhaps of reason (6)" , "Deprived of, perhaps by death" .)
