Blazing with a loud anger (5)
I believe the answer is:
afire
'blazing' is the definition.
(synonyms)
'with a loud anger' is the wordplay.
'with' is a charade indicator (letters next to each other).
'loud' becomes 'f' (short for forte - 'loud' in music).
'anger' becomes 'ire' (ire is intense rage).
'a' put next to 'f' is 'af'.
'af'+'ire'='AFIRE'
(Other definitions for afire that I've seen before include "lit up" , "Blazing - excited" , "Ablaze" , "Alight" , "in flames" .)
