Friend shot by friend from Paris (5)
I believe the answer is:
amigo
'friend' is the definition.
('friend' in Spanish)
'shot by friend from paris' is the wordplay.
'shot' becomes 'go' (both can mean an attempt).
'by' means one lot of letters go next to another.
'friend from paris' becomes 'ami' ('friend' in French).
'go' after 'ami' is 'AMIGO'.
(Other definitions for amigo that I've seen before include "Foreign ally" , "Friend from Spain?" , "Mexican's mate" , "Mexican friend" , "friend abroad" .)
