Friend, compadre (5)
I believe the answer is:
amigo
I believe this is a double definition.
'friend' is the first definition.
('friend' in Spanish)
'compadre' is the second definition.
(I've seen this in another clue)
(Other definitions for amigo that I've seen before include "friend abroad" , "Hispanic comrade" , "Foreign ally" , "Mate in Madrid?" , "buddy abroad?" .)
