Idol shot, died (3)
I believe the answer is:
god
'idol' is the definition.
('god' can be a synonym of 'idol')
'shot died' is the wordplay.
'shot' becomes 'go' (I've seen this in other clues).
'died' becomes 'd'.
'go'+'d'='GOD'
(Other definitions for god that I've seen before include "Being upstairs" , "Superhuman being" , "Eg, Quetzalcoatl" , "Mars or Mercury, say" , "Anubis?" .)
