Persian fairy (4)
I believe the answer is:
peri
'persian fairy' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for peri that I've seen before include "Type of disembodied spirit or graceful young girl" , "A vision of loveliness" , "Fairy of Persian myth" , "Fairy (Pers. mythology)" , "Beautiful fairy" .)
