Gilpin of "Frasier” (4)
I believe the answer is:
peri
'gilpin of frasier' 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 "Fairy could be ripe" , "Type of disembodied spirit or graceful young girl" , "Old Persian fairy" , "Prefix denoting 'around'" , "A vision of loveliness" .)
