Elf, fairy (6)
I believe the answer is:
sprite
I believe this is a double definition.
'elf' is the first definition.
(I've seen this before)
'fairy' is the second definition.
(I know that fairy can be written as sprite)
(Other definitions for sprite that I've seen before include "Puck, say" , "Impish type" , "Goblin, elf or imp" , "Pet, sir, could be a goblin" , "Nimble elf-like creature - icon in computer game" .)
