Ruffle someone's feathers with a Green remedy (6)
I believe the answer is:
enrage
'ruffle' is the definition.
The answer and definition can be both to do with human feelings as well as being verbs in their base form.
Maybe you can see an association between them that I don't see?
'someone's feathers with a green remedy' is the subsidiary indication.
'a green' anagrams to 'enrage'.
However, I am not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for enrage that I've seen before include "Make mad" , "Genera (anag.)" , "Make someone extremely angry" , "Infuriate, make very angry" , "Incense" .)
