Slovene language
Slovene is an Indo-European language belonging to the Western subgroup of the South Slavic branch of the Slavic languages, together with Serbo-Croatian. It is close to the Chakavian and especially Kajkavian dialects of Serbo-Croatian, but further from the Shtokavian dialect, the basis for the Bosnian, Croatian, Montenegrin, and Serbian standard languages. Furthermore, Slovene shares certain linguistic characteristics with all South Slavic languages, including those of the Eastern subgroup, such as Bulgarian.
