Church Slavonic

The first Slavic literary language created in the 9th century by Saints Cyril and Methodius for Slavic missionary work. First written in Glagolitic script, later converted to Cyrillic. Still used today as the liturgical language of the Russian, Serbian, and Bulgarian Orthodox Churches. As the linguistic prototype of the entire Slavic language family, it is an essential foundation for studying Russian, Ukrainian, Serbian, and Bulgarian.
