Slavic Languages

Slavic languages, also called Slavonic languages, group of Indo-European languages spoken in most of eastern Europe, much of the Balkans, parts of central Europe, and the northern part of Asia. The Slavic languages, spoken by some 315 million people at the turn of the 21st century, are most closely related to the languages of the Baltic group (Lithuanian, Latvian, and the now-extinct Old Prussian), but they share certain linguistic innovations with the other eastern Indo-European language groups (such as Indo-Iranian and Armenian) as well. From their homeland in east-central Europe (Poland or Ukraine), the Slavic languages have spread to the territory of the Balkans (Bulgarian; Macedonian; Slovene; and Serbian, Bosnian, Croatian, and Montenegrin [sometimes grouped together as Bosnian-Croatian-Montenegrin-Serbian]), central Europe (Czech and Slovak), eastern Europe (Belarusian, Ukrainian, and Russian), and the northern parts of Asia (Russian). In addition, Russian is used as a second language by most inhabitants of the countries that were formerly part of the Soviet Union. Some of the Slavic languages have been used by writers of worldwide significance (e.g., Russian, Polish, and Czech), and the Church Slavonic language remains in use in the services in the Eastern Orthodox Church.
