Nonconformist converted residents (9)
I believe the answer is:
dissenter
'nonconformist' is the definition.
(a nonconformist dissents from convention)
'converted residents' is the wordplay.
'converted' indicates anagramming the letters.
'residents' is an anagram of 'DISSENTER'.
(Other definitions for dissenter that I've seen before include "One who objects" , "One who differs among residents" , "Nonconformist" , "one not C of E" , "One who disagrees out of tiredness" .)
