Unenviable destiny (4)
I believe the answer is:
doom
'unenviable destiny' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for doom that I've seen before include "Destiny; ruin" , "__ and gloom" , "Fate, destiny" , "Downfall" , "Mood of condemnation" .)
