The article highlights the problem of the typology of dialects of the Middle Volga region. Particular attention is paid to secondary dialects with signs of South Russian dialect bases, the status of which in the Volga atlases is determined ambiguously. The area of the described dialect type is indicated. It is indicated that in the left-bank part of the Middle Volga region, in the so-called Trans-Volga region, there is a high probability of the existence of secondary Central Russian dialects with the preservation of signs of southern Russian maternal stems. The main source is data from regional atlases. The materials of dialectological expeditions to the villages of the Samara region are used. The description of the typological characteristics of the secondary dialects with a southern base, which are designated on the maps of regional atlases as Central Russian, is based on the analysis of isogloss of phonetic, grammatical and proper lexical dialect phenomena. In dialects with a completed transition to Central Russian, typologically significant South Russian features are types of yakany with the preservation of vowel dissimilation, obstruent pronunciation of g of secondary origin and other phonetic, morphological and lexical features that make up the series of two-term dialectal correspondences. According to the linguistic basis, such dialects are often polydialectal. In some dialects, the South Russian basis is not in doubt, and we can only state the beginning of the transition to the Central Russian type. The question is raised about the existence of secondary dialect types, formed as a result of the assimilation of dialects of the South Russian dialect with other dialects, not only in the Volga region, but also in other territories with favorable conditions for inter-dialectal contact. It is concluded that the presence of the Central Russian type and South Russian bases in the described dialects is possible only if there is a sufficient amount of information on typologically significant levels of the dialect language, in which systemic relations are clearly manifested and which are represented on linguistic maps by stable isoglosses. Data on secondary types of dialects should be based on the structural-typological classification of dialectal phenomena of various levels, including the lexical one.
