The Slavic languages (also called Slavonic languages) are the Indo-European languages native to the Slavic peoples, originally from Eastern Europe. They are thought to descend from a proto-language called Proto-Slavic spoken during the Early Middle Ages, which in turn is thought to have descended from the earlier Proto-Balto-Slavic language, linking the Slavic languages to the Baltic languages in a Balto-Slavic group within the Indo-European family.
