Put right about couple (6)
I believe the answer is:
repair
'put right' is the definition.
(I've seen this before)
'about couple' is the wordplay.
'about' becomes 're' (regarding).
'couple' becomes 'pair' (synonyms).
're'+'pair'='REPAIR'
(Other definitions for repair that I've seen before include "Restore to good order" , "Make one's way (to); fix" , "Travel or proceed toward some place" , "darn?" , "Mend - go" .)
