European? This could be French (6)
I believe the answer is:
polish
I believe this is a double definition.
'european?' is the first definition.
(I've seen this before)
'this could be french' is the second definition.
(French polish is a type of wood finish)
(Other definitions for polish that I've seen before include "See 1" , "Buff - from Poland" , "Substance used to produce shine" , "Language (linked to spitting?)" , "Shine for a European" .)
