Greed for wealth (7)
I believe the answer is:
avarice
'greed for wealth' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for avarice that I've seen before include "One of seven deadly sins" , "Stinginess" , "Insatiable lust" , "Insatiable desire for wealth" , "Rapacity" .)
