In the morning, I leave with friend (5)
I believe the answer is:
amigo
'friend' is the definition.
('friend' in Spanish)
'in the morning i leave' is the wordplay.
'in the morning' becomes 'am' (short for ante meridiem - before noon).
'leave' becomes 'go' (to go is to depart or leave).
'am'+'i'+'go'='AMIGO'
'with' acts as a link.
(Other definitions for amigo that I've seen before include "Friend in Spanish-speaking area" , "friend from Barcelona" , "Friend, comrade" , "Pal from Madrid?" , "A Spanish pal" .)
