The South Slavic languages are one of the three branches of the Slavic languages. They have approximately 30 million speakers, chiefly in the Balkans. They are commonly divided into eastern and western subgroups, with Bulgarian and Macedonian in the former, and Serbo-Croatian and Slovene in the latter. South Slavic languages are separated geographically from speakers of the other two Slavic branches by a belt of Austrian German, Hungarian and Romanian speakers, none of which are Slavic.
