Flesh-eating giant (4)
I believe the answer is:
ogre
'flesh-eating giant' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ogre that I've seen before include "Cruel giant of folklore" , "Bogeyman" , "Fairy tale giant" , "Monstrous person" , "Monstrous creature" .)
