Believe gold might satisfy him? (8)
I believe the answer is:
creditor
'satisfy him?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'believe gold' is the wordplay.
'believe' becomes 'credit' (I've seen this before).
'gold' becomes 'or' ('or' is the heraldic name for gold).
'credit'+'or'='CREDITOR'
'might' acts as a link.
Can you help me to learn more?
(Other definitions for creditor that I've seen before include "Moneylender" , "One who's owed money" , "one to whom money is due" , "Lender" , "he advances to you" .)
