It's thrown in hurry (4)
I believe the answer is:
dart
This clue is a double definition.
'it's thrown' is the first definition.
'hurry' is the second definition.
(darting is a kind of hurrying)
'in' acts as a link.
(Other definitions for dart that I've seen before include "Small pointed projectile" , "Small narrow pointed missile" , "Tuck; arrow" , "Dash; pointed missile" , "Arrow - go fast" .)
