Test won via dismissal of openers from European country (7)
I believe the answer is:
estonia
'european country' is the definition.
(country in Europe)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for estonia that I've seen before include "East European country" , "European country, capital Tallinn" , "Republic in the Baltic region, once part of USSR" , "Nation" , "Republic in northeastern Europe" .)
