History

Balto-Slavic languages, hypothetical language group comprising the languages of the Baltic and Slavic subgroups of the Indo-European language family. Those scholars who accept the Balto-Slavic hypothesis attribute the large number of close similarities in the vocabulary, grammar, and sound systems of the Baltic and Slavic languages to development from a common ancestral language after the breakup of Proto-Indo-European. Those scholars who reject the hypothesis believe that the similarities are the result of parallel development and of mutual influence during a long period of contact.
