Right to amend (7)
I believe the answer is:
correct
This clue is a double definition.
'right' is the first definition.
(I know that right can be written as correct)
'amend' is the second definition.
(I know that amend is a more specific form of the action correct)
'to' is the link.
(Other definitions for correct that I've seen before include "Free from error" , "True; put right" , "Set right - punish" , "Adjust, make right" , "See 6" .)
