Flying toy (4)
I believe the answer is:
kite
'flying toy' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for kite that I've seen before include "flyer" , "Quadrilateral; bird" , "It's flown in the wind at the end of a string" , "Kind of toy flown on string" , "aeroplane" .)
