In the morning, I shot friend (5)
I believe the answer is:
amigo
'friend' is the definition.
('friend' in Spanish)
'in the morning i shot' is the wordplay.
'in the morning' becomes 'am' (short for ante meridiem - before noon).
'shot' becomes 'go' (both can mean an attempt).
'am'+'i'+'go'='AMIGO'
(Other definitions for amigo that I've seen before include "Mexican friend" , "Friend, comrade" , "buddy abroad?" , "Hispanic friend" , "Spanish word meaning friend" .)
