Loaner (6)
I believe the answer is:
lender
'loaner' is the definition.
(I know that loaner can be written as lender)
This is all the clue.
(Other definitions for lender that I've seen before include "One making advances" , "One who advances money" , "Neither a borrower nor a ... be, it's said" , "Loan shark" , "Bank or building society" .)
