Country letter for Greeks and the French (5)
I believe the answer is:
chile
'country' is the definition.
(Chile is a country)
'letter for greeks and the french' is the wordplay.
'letter' becomes 'c'.
'for greeks' becomes 'hi' (I can't justify this - if you can you should believe this answer much more).
'and' means one lot of letters go next to another.
'the french' becomes 'le' ('the' in French).
'c'+'hi'+'le'='CHILE'
Can you help me to learn more?
(Other definitions for chile that I've seen before include "S. American nation" , "Most southerly American country" , "Country liberated by Bernardo O'Higgins" , "Long narrow country" , "Country of S. America" .)
