See and possibly rescind (7)
I believe the answer is:
discern
'see' is the definition.
(thesaurus)
'possibly rescind' is the wordplay.
'possibly' indicates an anagram.
'rescind' is an anagram of 'DISCERN'.
'and' acts as a link.
(Other definitions for discern that I've seen before include "Notice" , "spot" , "Pick out" , "See" , "Recognise, find out" .)
