Far from pleased, I indulge in abuse (5)
I believe the answer is:
irate
'far' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I don't see?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for irate that I've seen before include "Annoyed, exasperated" , "Spitting feathers" , "Aggrieved" , "Magical rod" , "Infuriated" .)
