Suffer, having no interest to wipe out debts (5)
I believe the answer is:
incur
'suffer' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for incur that I've seen before include "Become subject to (penalty)" , "Become subject to (something unwelcome)" , "Enter into" , "Bring something unpleasant on oneself (5)" , "contract" .)
