Rescind incorrect notice (7)
I believe the answer is:
discern
'notice' is the definition.
(thesaurus)
'rescind incorrect' is the wordplay.
'incorrect' indicates an anagram.
'rescind' with letters rearranged gives 'DISCERN'.
(Other definitions for discern that I've seen before include "Cinders (anag)" , "Detect" , "Recognise, find out" , "Perceive - distinguish" , "Pick out" .)
