Goblin or fairy (6)
I believe the answer is:
sprite
I believe this is a double definition.
'goblin' is the first definition.
(I've seen this in another clue)
'fairy' is the second definition.
(I know that fairy can be written as sprite)
(Other definitions for sprite that I've seen before include "Small, playful fairy" , "Puck, say" , "Supernatural being" , "Brownie" , "Goblin, elf or imp" .)
