European language that might be French! (6)
I believe the answer is:
polish
This might be a double definition.
'european' is the first definition.
(I've seen this before)
'language that might be french' is the second definition.
'Polish' can be an answer for 'language' (Polish is a language). I am not sure about the rest of the definition.
Can you help me to learn more?
(Other definitions for polish that I've seen before include "Rub - European" , "Of one from Warsaw, say" , "Perfect" , "taught in finishing school?" , "Rub to a gloss" .)
