Reparation (6)
I believe the answer is:
amends
'reparation' is the definition.
(both can mean making up for doing something wrong)
This is all the clue.
(Other definitions for amends that I've seen before include "Make these to atone for injuries or loss caused" , "Corrects" , "Atonement" , "Sad men (anag.)" , "Makes changes, to a text say" .)
