Cemetery spirit (5)
I believe the answer is:
ghoul
'cemetery spirit' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ghoul that I've seen before include "Corpse-loving phantom" , "Spirit that robs graves and devours corpses" , "Gruesome fiend" , "Spectre, fiend" , "malevolent spirit" .)
