I believe the answer is:

european

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

'dane?' is the definition.
(dane is a kind of European)

I don't understand the remainder of the clue.

(Other definitions for european that I've seen before include "Dubliner, Londoner, Berliner, for instance" , "The E of the EU" , "Anti-UKIP" , "possibly from Italy" , "Swede, perhaps?" .)

I've seen this clue in The Telegraph.
