Fine at avoiding angry passion (4)
I believe the answer is:
'passion' is the definition.
(I know that fire is a type of passion)
'fine at avoiding angry' is the wordplay.
'fine' becomes 'f' (abbreviation e.g. condition of old coins, books).
'avoiding' is a deletion indicator.
'angry' becomes 'irate' (irate can mean angry or annoyed).
'irate' with 'at' taken out is 'ire'.
(Other definitions for fire that I've seen before include "Blaze - sack" , "Sack; conflagration" , "Let off" , "... or combustion" , "Sack; discharge (a gun)" .)
