Greediness (7)
I believe the answer is:
avarice
'greediness' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for avarice that I've seen before include "Greed for gain" , "Extreme greed for wealth" , "Excessive greed for wealth" , "Rapacity" , "Stinginess" .)
