Purpose of the study was to designate the genre features of the pobyvalshchina and identify its linguistic specificity. The authors establishing the semantic content of the term and determining the legitimacy of using this term to the genre that is common among the speakers of Russian old-time dialects in the Tobolsk Irtysh Land. The research is based on the practice of collecting, describing, and mapping dialectisms of the Russian language. A brief analysis of the texts showed that the pobyvalshchina of this region is characterized by traditional features of other genres of oral and prose narration. It differs from other epic genres as it is designed to teach the listener and convey some kind of guidance in everyday life. The linguistic framework of the pobyvalshchina is made up of colloquial vocabulary.

The study proves that the prefixal method is the main way of forming adverbs of manner in the Old Russian language. The teaching of language historians about the formation of Old Russian adverbs is based on a stable idea about the ongoing or incomplete adverbialization of prepositional-substantive or prepositional-attributive combinations. This viewpoint on adverbs affected the historical coverage of this part of speech not only in academic research but also in educational literature. Adverbs of manner, which are integral grammatical and lexical components of the Russian language, have not yet been a research subject.

We study formation the issue of the adverbs of place in the Old Russian language in historical aspect. The material for the research is the contexts with adverbs of place, extracted by the method of continuous sampling from the published Old Russian writing monuments. To identify the way of derived adverbs origin and to establish its initial derivational structure, as the main ones in the work there are used derivative and morphemic analyzes in a synchronous environment, as well as elements of contextual analysis, which made possible to identify and clarify the dependence of lexical meaning of the adverb on the context. We establish that the leading way of forming the adverbs of place in the Old Russian language was the prefix; the role of the generating base was played by the primary polysemous adverb, which, because of the meaning of derivative formant, was formed into a new monosemous adverb. We conclude that the reconstruction of real history of the adverbs is possible only on the basis of comparing contexts in connection with each other, on the basis of a derivative analysis of the structure of adverbs in a synchronous cut and on the basis of identifying derivative types of the adverbs in diachrony and synchronicity.
