Made good on, as a loan (6)
I believe the answer is:
repaid
'made good on as a loan' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for repaid that I've seen before include "Compensated" , "Recompensed" , "Reimbursed" , "Returned" , "Refunded or rewarded" .)
