Fairy, elf (5)
I believe the answer is:
pixie
This clue is a double definition.
'fairy' is the first definition.
(I know that pixie is a type of fairy)
'elf' is the second definition.
(I know that elf can be written as pixie)
(Other definitions for pixie that I've seen before include "Elfin fairy" , "Small supernatural being in fairy tales" , "Supernatural being with pointed ears" , "Little person" , "Creature like fairy or elf" .)
