the article is devoted to the variation of graphics and orthography of the Sosva dialect of the modern Mansi language, which is part of the Northern dialect and is the basis of the written and literary language. Objective: identification and description of the graphic and orthographic variation of the modern Mansi literary language (Sosva dialect). Research materials: lexical units of the Sosva dialect of the Northern dialect of the Mansi language that have more than one spelling variant. Results and novelty of the research: the article for the first time in modern Mansi linguistics considers the issue of graphic and orthographic variation. The relevance of the research is due to the specifics of graphic and orthographic norms and difficulties that arise in choosing variant spellings. The article examines the linguistic content of variation and the norm related to spelling; provides examples of variant spellings, on the basis of which zones of orthography instability are identified. It has been revealed that graphic variation currently consists solely in spelling words with allophones c’ – sch. In realization of the orthography norms, the most significant contradictions are presented in choosing of the variants of the joined-up, separate or hyphenated spelling of words, phonetic and morphological variants, uppercase or lowercase letters in complex and compound anthroponyms, spelling of borrowed words. The practical significance of the discussion of this issue lies in the fact that its results will contribute to the development of linguistic variability and normative studies and can be used in the development of a typology of the orthographic variants, a new set of rules for graphics and orthography of the Mansi language based on unified norms, in compiling dictionaries of the Mansi language.
