Btw: Hungarian language is also changing continously. (...or: it is continously changing - the word order is not so strict in Hungarian). Even the letters was different in ancient times - originally was runic writing.
Nowadays we couldn't umderstand the ancient Hungarian neither speaking nor writing.
And last but not least the Hungarian comes from "Hun" (refer Attila the Hun, called "Whip of God), but our country's name is "Magyarország" in Hungarian, which comes grom "Magyar". This refers to an ancient myth about the Wonder Deer, and about brothers Hunor and Magor. They became tribe leaders later called Huns and Magyars.
