"Aladdin" parrot (4)
I believe the answer is:
iago
'aladdin parrot' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for iago that I've seen before include "stage villain" , "villain in play" , "Othello's evil counsellor" , "Othello's enemy" , "Evil character in Othello" .)
