Woodland fairy (3)
I believe the answer is:
elf
'woodland fairy' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for elf that I've seen before include "Mischievous fairy No.2" , "Woodland sprite" , "A leprechaun" , "Pixie (able to cobble?)" , "One of the little folk" .)
