Leave with mate from Paris to see Spanish counterpart (5)
I believe the answer is:
amigo
'see spanish counterpart' is the definition.
The definition suggests a singular noun which matches the answer.
'leave with mate from paris' is the wordplay.
'leave' becomes 'go' (to go is to depart or leave).
'with' means one lot of letters go next to another.
'mate from paris' becomes 'ami' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'go' after 'ami' is 'AMIGO'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for amigo that I've seen before include "Foreign ally" , "Mexican friend" , "Male (Spanish?) friend" , "Friend in Spanish-speaking areas" , "buddy abroad?" .)
