Abstract
Lexicostatistical studies of the connection between the Buryat-Evenki toponyms of the Irkutsk region and the Russian language have been carried out. The study used a method of a matrix of proximity measures between the list of toponyms and the list of Russian words from the frequency Russian-Buryat dictionary, which are translated into consonantal classes according to A. Dolgopolsky.
Closeness measures between two words composed of consonantal classes are described using the Ratcliffe — Oberschelp numerical metric. A matrix of word proximity measures has been calculated, numbering about 800,000 elements. The averages of the maximum measures in rows and columns and the average measure over the entire field of the matrix are found. Statistical studies show the historical connection of a group of toponyms with the Russian language at the level of 85 %. The meaning of some Buryat-Evenki toponyms in the Russian language has been restored.
