Priests scattered fairies (7)
I believe the answer is:
sprites
'fairies' is the definition.
('sprite' can be a synonym of 'fairy')
'priests scattered' is the wordplay.
'scattered' indicates anagramming the letters.
'priests' with letters rearranged gives 'SPRITES'.
(Other definitions for sprites that I've seen before include "Brownies" , "goblins?" , "Elves or fairies" .)
