One who's owed (8)
I believe the answer is:
creditor
'one who's owed' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for creditor that I've seen before include "Person to whom debt is owed" , "One who's owed money" , "He's the one owed the money" , "one to whom money is due" , "Lender" .)
