Greed displayed by girl taking pudding (7)
I believe the answer is:
avarice
'greed' is the definition.
(avarice is a kind of greed)
'displayed by girl taking pudding' is the wordplay.
'displayed by' is a charade indicator (letters next to each other).
'girl' becomes 'ava'.
'taking pudding' becomes 'rice' (I can't explain this - if you can you should believe this answer much more).
'ava'+'rice' is 'AVARICE'.
Can you help me to learn more?
(Other definitions for avarice that I've seen before include "A deadly sin" , "Wanting to be rich" , "Insatiable lust" , "Greed, covetousness" , "Sway, control" .)
