Makes amends (for) (6)
I believe the answer is:
atones
'makes amends for' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for atones that I've seen before include "Makes reparation" , "Does penance with a stone" , "Makes up for wrong done with a stone" , "Makes amends for sin" , "Make amends for sin" .)
