The Dnieper-Oka language (Eastern Peripheral Baltic, Dnieper-Baltic) is one or several extinct Baltic languages, the existence of which is indicated by toponymic data. It occupied the upper reaches of the Daugava, the basins of the upper Dnieper and Desna, the upper and middle Oka and the Seym. Beginning in the 7th and 8th centuries, the Baltic dialects of the region were replaced by Old East Slavic. The only known subdivision of the Dnieper-Oka language is the Golyad language.^[1]
