Persian fairy (4)
I believe the answer is:
peri
'persian fairy' is the definition.
(I've seen this before)
This is the entire 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" .)
