About Mansi origin of the Russian dialect word nyurka ‘small pike’, ‘small fish’

in some Districts of the Sverdlovsk and Perm Oblasts, the words nyur, nyurka, nyurovka, nyrka and some others similar words with the meaning ‘small pike’ (sometimes ‘small fish’) are fixed. The etymological solutions earlier proposed for this lexical nest do not sufficiently take into account the form, semantics and areal of the Russian dialect words. In the article, version about the Mansi origin of the analyzed lexemes is suggested. Objective: to identify the origin of the Russian dialect words nyurka, nyur and others words with the meaning ‘small pike’ (sometimes ‘small fish’). Research materials: published monographs, articles and dictionaries, as well as unpublished manuscript monuments of the Mansi writing system of the late XVIII century. Results and novelty of the research: for the first time, a consistent version of the origin of the Russian dialect words nyurka, nyur and others words with the meaning ‘small pike’ (sometimes ‘small fish’) from the Mansi language is proposed. It is identified that some Russian lexemes can reflect the phonetics of the substrate Mansi dialects of the Western Urals. The results of the study introduce into scientific circulation the new data about the substrate Mansi dialects that existed in the Middle Urals, and about the vocalism of the first syllable in the Mansi dialects.
