The Slavonic languages, also called Slavic languages, are a group of closely related languages spoken by the Slavic peoples in Eastern Europe, the Balkans, parts of Central Europe and the northern part of Asia. All Slavic languages descended from Proto-Slavic. Some 315 million people speak a Slavic language at the turn of the 21st century, most closely related to the languages of the Baltic group: Lithuanian, Latvian, and the now-extinct Old Prussian. Some of the Slavic languages have been used by writers of worldwide significance (e.g., Russian, Polish, Czech), and the Church Slavonic language remains in use in the services in the Eastern Orthodox Church.
