Devour; predatory beast (4)
I believe the answer is:
wolf
I believe this is a double definition.
'devour' is the first definition.
(I know that devour can be written as wolf)
'predatory beast' is the second definition.
(Other definitions for wolf that I've seen before include "Eat hastily" , "Seducer - gobble down" , "shovel down" , "Lupine mammal" , "Pack-hunting animal" .)
