It breaks a fall from the sky (9)
I believe the answer is:
parachute
'it breaks a fall from the sky' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for parachute that I've seen before include "Drop from plane" , "Devise for making descent from an airplane" , "It breaks a fall from the sky" , "Eat up char for something to break your fall" , "Equipment to break a fall from the sky" .)
