Thieving large amount of money brought about fine expression of anger (9)
I believe the answer is:
pilferage
'thieving' is the definition.
(I know that pilferage is a type of thieving)
'large amount of money brought about fine expression of anger' is the wordplay.
'large amount of money' becomes 'pile' (I've seen this in another clue).
'brought about' is an insertion indicator.
'fine expression of' becomes 'f' (I can't justify this - if you can you should give a lot more credence to this answer).
'anger' becomes 'rage' (rage is a kind of anger).
'pile' enclosing 'f' is 'pilfe'.
'pilfe'+'rage'='PILFERAGE'
Can you help me to learn more?
(Other definitions for pilferage that I've seen before include "Theft (of small items)" , "Petty theft" , "Minor stealing" , "Thefts" .)
