Bully with threatening look taking off jacket (3)
I believe the answer is:
cow
'bully' is the definition.
(cow can mean to bully or oppress)
'with threatening look taking off jacket' is the wordplay.
I cannot really see how this works, but
'with' could be 'w' (short for with) and 'w' is present in the answer.
The remaining letters 'co' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for cow that I've seen before include "Bovine female" , "Female farm animal" , "Subdue with threats or force" , "female whose homecoming is indefinitely delayed" , "Frighten with intimidations" .)
