Man-eating giants (5)
I believe the answer is:
ogres
'man-eating giants' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ogres that I've seen before include "Giant types" , "Monstrous giants and man-eaters" , "Awful brutes" , "Man-eating giants of folklore" , "She-giant of fairy tale" .)
