In my opinion that country in Central-Europe is something of a role-model for small countries. I really admire the Hungarians for their ability to have been able to keep their own language. They are at the crossroads of the Slavic and Germanic nations and have been pressurised by both for centuries but yet they have maintained their own culture and language.
I really feel a great deal of admiration for that country as it belongs to the same Fenno-Ugric branch of nations and languages as my own one does. However, Hungarian is a sub-branch of its own. Finns and Estonians can understand each other to some degree but no-one can understand Hungarian except themselves. Many Hungarians say that theirs is the most isolated country and culture in Europe, a claim which I find a bit exaggerated given the location of the country in the heart of Europe.
However, the Hungarian language is something completely unrelated to any other language.The closest surviving relatives of the language are some almost extinct languages on the Siberian steppes. Hungary is really a country, a nation and a language of its own.
Well done for them to have had their language survived at that part of the continent. If you compare to other small nations, The Finns and the Estonians have been able to preserve their languages because of their remote location, the Celtic nations have lost their languages.
