Remedy, set right (7)
I believe the answer is:
redress
I believe this is a double definition.
'remedy' is the first definition.
(I know that remedy can be written as redress)
'set right' is the second definition.
(I've seen this before)
(Other definitions for redress that I've seen before include "Correct" , "remedy" , "Prepare again - satisfaction" , "set things right" , "Get back into gear" .)
