The Prehistory of the Balto-Slavic Accent has been written to fill a gap. The interested non-specialist can easily learn about the complex accent systems of the individual Baltic and Slavic languages and how they relate to each other. But the reader interested in the Proto-Balto-Slavic parent system, and how it evolved from the very different system of Proto-Indo-European, has few reliable places to turn. The goal of this book is to provide an accentological interface between Indo-European and Balto-Slavic--to identify and explain the accent shifts and other early changes that give the earliest stages of Baltic and Slavic their distinctive prosodic cast.
