Can the Russian language be regarded as pluricentric since it is used in various countries and regions of the world where different varieties of the language have evolved? Indeed, in Russia, Belarus, Kazakhstan, Kyrgyzstan and some other countries, Russian is used as the official language of state bodies and institutions. However, each of these countries has its own linguistic and cultural specificities of grammar, vocabulary and phonetics, which distinguish it from other varieties of the Russian language. In addition, the Russian language is used in countries where it is not an official language, such as Finland, Germany, Israel. There it also has its own characteristics caused by interaction with different languages and cultures. The goal of the study is to show that all these varieties of the Russian language can be viewed as pluricentric variants, i.e. as independent language systems with their own characteristics and differences. Theoretically, the recognition of the Russian language as pluricentric would help to better understand the old and emerging varieties of the language and establish their relationship with each other, making it possible to compare different varieties of the language with each other at all linguistic levels. Practically, such recognition would also make it possible to trace the adaptive possibilities of the Russian language, which vary depending on the region and cultural environment, which in turn will diversify and deepen the study of the Russian language, making it more interesting for the learner. Based on the theory of pluricentricity, the paper compares practices of the language use and seeks to establish commonalities of Russian pluricentrism. Moreover, it highlights the unique features of the Kazakhstan language variety while demonstrating new opportunities for studying the flexible adaptability of the language. This approach will contribute to better understanding and appreciating the richness and versatility of the Russian language as it is used around the world.
