Intimidate; animal (3)
I believe the answer is:
cow
I believe this is a double definition.
'intimidate' is the first definition.
(I've seen this before)
'animal' is the second definition.
(I know that cow is a class)
(Other definitions for cow that I've seen before include "Unnerve" , "Intimidate; an animal" , "Subdue in bovine manner?" , "Source of milk" , "Female of domestic cattle" .)
