Snapped 'Try!' (4)
I believe the answer is:
shot
This clue is a double definition.
'snapped' is the first definition.
('shoot' can be a synonym of 'snap')
'try' is the second definition.
(shot is a kind of try)
(Other definitions for shot that I've seen before include "Short drink; attempt" , "Ruined; photo" , "Discharged a weapon" , "Charge" , "Fired - attempt" .)
