Russian spelling on the way from disorder to uniform. Book review: Naumenko S. V. Variativnost’ v russkoy orfografii (18-20 vv.) [Variation in Russian orthography (18th-20th centuries)]. Krasnoyarsk, 2019, 356 p.

The reviewed monograph of S. V. Naumenko gives a detailed description of variability in Russian spelling of the 18th-20th centuries. It is not only the graphic practice that is studied but its understanding in the theoretical, normative, and methodological works of linguists. S. V. Naumenko describes the complex and contradictory path of Russian spelling and orthography to the elimination of unjustified variation. A careful analysis of the linguistic works and their content is conducted. Also, the material from explanatory and spelling dictionaries is considered, with spelling variants within a single book (intra-variants) being indicated and compared with other books in parallel (extra-variants). It can be concluded that S. V. Naumenko has succeeded in demonstrating a wide variety of spellings and the diversity of scholars’ opinions.
