UN issued another financial penalty for being rude (9)
I believe the answer is:
unrefined
'being rude' is the definition.
('unrefined' can be similar in meaning to 'rude')
'un issued another financial penalty' is the wordplay.
I cannot quite understand how this works, but
'un' is within the answer.
'another' could be 're' (I've seen this in other clues) and 're' is located in the answer.
'penalty' could be 'fine' (a financial penalty) and 'fine' is located in the answer.
A single letter 'd' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for unrefined that I've seen before include "rude" , "Crude" , "Coarse" , "Rough" .)
