Buddy, in Baja (5)
I believe the answer is:
amigo
'buddy in baja' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for amigo that I've seen before include "Male (Spanish?) friend" , "Hispanic comrade" , "Friend in Spanish-speaking areas" , "friend from Barcelona" , "Quixote's friend" .)
