Burning anger after a fine (5)
I believe the answer is:
afire
'burning' is the definition.
(on fire)
'anger after a fine' is the wordplay.
'anger' becomes 'ire' (ire is intense rage).
'after' is a charade indicator (letters next to each other).
'fine' becomes 'f' (abbreviation).
'a'+'f'='af'
'ire' put after 'af' is 'AFIRE'.
(Other definitions for afire that I've seen before include "Burning" , "lit up" , "Blazing - excited" , "in flames" , "Alight" .)
