Forgive, absolve (6)
I believe the answer is:
pardon
I believe this clue is a double definition.
'forgive' is the first definition.
(I know that pardon is a more specific form of the action forgive)
'absolve' is the second definition.
(I've seen this in another clue)
(Other definitions for pardon that I've seen before include "Let off" , "Excuse or absolve" , "Forgiveness - I beg yours" , "Forgive or excuse (an offence)" , "Forgive (an error)" .)
