Frighten the milk provider (3)
I believe the answer is:
cow
'frighten' is the definition.
(I know that cow is a more specific form of awe)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for cow that I've seen before include "Female of domestic cattle" , "Subdue the spirit" , "Female domestic animal" , "Female domestic mammal" , "Source of milk" .)
