Nonconformist to pour scorn on record (9)
I believe the answer is:
dissenter
'nonconformist' is the definition.
(thesaurus)
'pour scorn on record' is the wordplay.
'pour scorn on' becomes 'diss'.
'record' becomes 'enter' ('enter' can be a synonym of 'record').
'diss'+'enter'='DISSENTER'
'to' acts as a link.
(Other definitions for dissenter that I've seen before include "One who disagrees out of tiredness" , "One who objects" , "One who disagrees among residents" , "One expressing disagreement" , "One not agreeing" .)
