I’m a nice cad, a perverted RA member, perhaps (11)
I believe the answer is:
academician
'ra member perhaps' is the definition.
(RA is the Royal Academy)
'i'm a nice cad a perverted' is the wordplay.
'perverted' is an anagram indicator.
'im'+'a'+'nice'+'cad'+'a'='imanicecada'
'imanicecada' is an anagram of 'ACADEMICIAN'.
(Other definitions for academician that I've seen before include "Institutional scholar" , "A maniac dice (anag) - RA" , "Member of a teaching establishment" , "Eg, member of the RA" , "Distinguished scholar" .)
