Milk maker (3)
I believe the answer is:
cow
'milk maker' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cow that I've seen before include "Subdue the spirit" , "Intimidate; quadruped" , "female whose homecoming is indefinitely delayed" , "Browbeat" , "Intimidate; milk producer" .)
