Humanoid monster (3)
I believe the answer is:
orc
'humanoid monster' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for orc that I've seen before include "Sea monster; or Tolkien character" , "Tolkien ogre" , "Mythical monster" , "Killer-whale" , "Tolkien goblin" .)
