Slovenian, or Slovene as it is also known, is one of the oldest languages in Europe. The language can be dated back to a set of religious texts called The Freising Manuscripts, which are believed to be from the ninth century.
There are around 2.5 million native Slovenian speakers globally, with about two million of these living in Slovenia itself. However, for such a small country, Slovenian has many dialects, around 50 in total. It is generally accepted as the most diverse Slavic language in this respect.
Interestingly the Slovenian language is very clean; it does not possess any curse words!
