His advances should be spurned (6)
I believe the answer is:
usurer
'his advances should be spurned' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
This is the entire clue.
Can you help me to learn more?
(Other definitions for usurer that I've seen before include "Shylock, for example" , "like Shylock" , "Unscrupulous moneylender" , "Iniquitous moneylender" , "Grasping money lender" .)
