Leaves with all debts settled (5)
I believe the answer is:
quits
'leaves' is the definition.
(quitting is a kind of leaving)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for quits that I've seen before include "On equal terms" , "Abandons" , "On even terms again" , "Leaves - all square" , "Even - leaves" .)
