polish

I'm a little stuck... Click here to teach me more about this clue!

'european' is the definition.
(I've seen this before)

I don't understand how the rest of the clue works.

(Other definitions for polish that I've seen before include "Brush up" , "'Buff, burnish (6)'" , "Of one from Warsaw, say" , "Give shine to" , "Shine with cloth,buff" .)

I've seen this clue in the Evening Standard.
