Subdue animal (3)
I believe the answer is:
cow
I believe this is a double definition.
'subdue' is the first definition.
(I've seen this before)
'animal' is the second definition.
(cow is a kind of animal)
(Other definitions for cow that I've seen before include "female whose homecoming is indefinitely delayed" , "frighten as with threats" , "Female seal" , "Unnerve" , "Frighten with intimidations" .)
