Indo-European is understood to be the root language of almost all the languages spoken by Europeans today. It developed into ten major branches. Those important to understand the linguistic context of Lviv, our microcosm, include Balto-Slavic, Germanic, Hellenic, and Italic.
Balto-Slavic eventually branched into Baltic and Slavic languages.
Slavic developed in three directions: East, West, and South. Old East Slavic was the language spoken by Daniel of Halych, founder of Lviv in the mid-1200s, and by his descendants into the 1300s. Later it evolved into today’s Ukrainian, Belarusian, and Russian.
