A fighter gets ring for Spanish friend (5)
I believe the answer is:
amigo
'spanish friend' is the definition.
(I've seen this before)
'a fighter gets ring' is the wordplay.
'fighter' becomes 'mig' (I've seen this in other clues).
'gets' means one lot of letters go next to another.
'ring' becomes 'o'.
'a'+'mig'+'o'='AMIGO'
'for' is the link.
(Other definitions for amigo that I've seen before include "Pal from Madrid?" , "Male (Spanish?) friend" , "Mexican's mate" , "in a foreign land, my friend?" , "Friend in Spanish-speaking areas" .)
