In the morning, I leave friend in Madrid (5)
I believe the answer is:
amigo
'friend in madrid' is the definition.
(Spanish for friend)
'in the morning i leave' is the wordplay.
'in the morning' becomes 'am'.
'leave' becomes 'go'.
'am'+'i'+'go'='AMIGO'
(Other definitions for amigo that I've seen before include "Hispanic friend" , "Foreign ally" , "Friend, comrade" , "friend from Barcelona" , "A Mexican pal" .)
