End in servitude, miserably (6)
I believe the answer is:
demise
'end' is the definition.
(I know that demise is a type of end)
'in servitude miserably' is the wordplay.
'in' says the answer is hidden in the clue.
'DEMISE' is hidden in the letters of 'servitude miserably'.
(Other definitions for demise that I've seen before include "Death or expiration" , "The end of something" , "Death, collapse" , "Death or termination" , "Passing" .)
