Polish, maybe - certainly European! (6)
I believe the answer is:
french
'european' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for french that I've seen before include "-- Polish; -- stick" , "A Romance language" , "Word which may precede bean, chalk, cricket, horn" , "eg Marie Antoinette" , "Gallic" .)
