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. 請檢查|access-date=中的日期值 (幫助)

Kortlandt, Frederik, Baltica & Balto-Slavica: 5, 2009, Though Prussian is undoubtedly closer to the East Baltic languages than to Slavic, the characteristic features of the Baltic languages seem to be either retentions or results of parallel development and cultural interaction. Thus I assume that Balto-Slavic split into three identifiable branches, each of which followed its own course of development.
