Resort to put right (6)
I believe the answer is:
repair
I believe this is a double definition.
'resort' is the first definition.
(I know that resort can be written as repair)
'put right' is the second definition.
(I've seen this before)
'to' acts as a link.
(Other definitions for repair that I've seen before include "Restore; go" , "Mend - go" , "Make one's way (to); fix" , "darn?" , "Fix, mend" .)
