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

'language' is the definition.
(Slovak is an example)

I can't explain the rest of the clue.

(Other definitions for slovak that I've seen before include "One from Bratislava" , "Native of European republic" , "Native of Bratislava, for instance" , "Eg, native of Bratislava" , "East European language" .)

I've seen this clue in The Sunday Times and The Times.
