A state of well-being denied professional, bringing acrimony (8)
I believe the answer is:
asperity
'acrimony' is the definition.
(thesaurus)
'a state of well-being denied professional' is the wordplay.
I cannot really see how this works, but
'a' could be 'per' (eg 'one a day' means 'one per day') and 'per' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'bringing' is the link.
Can you help me to learn more?
(Other definitions for asperity that I've seen before include "'Sharpness, harshness (8)'" , "rough manner" , "Roughness, bitterness" , "Roughness of temper" , "Rough state" .)
