Spanish mate advanced with dynamism on M1 (5)
I believe the answer is:
amigo
'spanish mate' is the definition.
'amigo' can be an answer for 'mate' (thesaurus). I'm unsure of the 'spanish' bit.
'advanced with dynamism on m1' is the wordplay.
'advanced' becomes 'a'.
'with' is a charade indicator (letters next to each other).
'dynamism' becomes 'go' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'on' means one lot of letters go next to another.
'mg' becomes 'mi' (resembles Mg).
'go' put after 'mi' is 'migo'.
'a'+'migo' is 'AMIGO'.
Can you help me to learn more?
(Other definitions for amigo that I've seen before include "Pal from Madrid?" , "Friend in Spanish-speaking areas" , "Hispanic comrade" , "Foreign ally" , "Spanish word meaning friend" .)
