Proto-Balto-Slavic (PBS or PBSl) is a reconstructed hypothetical proto-language descending from Proto-Indo-European (PIE). From Proto-Balto-Slavic, the later Balto-Slavic languages are thought to have developed, composed of the Baltic and Slavic sub-branches, and including modern Lithuanian, Polish, Russian and Serbo-Croatian, among others.
Like most other proto-languages, it is not attested by any surviving texts but has been reconstructed using the comparative method. There are several isoglosses that Baltic and Slavic languages share in phonology, morphology and accentology, which represent common innovations from Proto-Indo-European times and can be chronologically arranged.
