Grasping money lender (6)
I believe the answer is:
usurer
'grasping money lender' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for usurer that I've seen before include "Shylock, say" , "Shylock's profession" , "One lending money at unreasonable rates" , "Person who charges excessive interest on loan" , "Moneylender who charges excessive rates of interest" .)
