Carinthia is the southernmost and least densely populated Austrian state, in the Eastern Alps, and is noted for its mountains and lakes. The main language is German. Its regional dialects belong to the Southern Bavarian group. Carinthian Slovene dialects, forms of a South Slavic language that predominated in the southeastern part of the region up to the first half of the 20th century, are now spoken by a small minority in the area.

Slovene or Slovenian is a Western member of South Slavic languages, which belong to the Balto-Slavic branch of the Indo-European language family. Most of its 2.5 million speakers are the inhabitants of Slovenia, majority of them ethnic Slovenes. As Slovenia is part of the European Union, Slovene is also one of its 24 official and working languages. Its syntax is highly fusional and characterized by dual grammatical number. Two accentual norms are used. Its flexible word order is often adjusted for emphasis or stylistic reasons, although basically it is a SVO language. It has a T–V distinction: the use of the V-form demonstrates a respectful attitude towards superiors and the elderly, while it can be sidestepped through the passive form.
