This article explores the dynamics of linguistic norms in the Russian literary language within the context of social media communication. The relevance of the study lies in the fact that digital platforms create new communicative conditions that reshape traditional language norms. The paper analyzes variability, simplification, and expressive tendencies in syntax, lexicon, and orthography. Furthermore, it demonstrates that linguistic norms in social media are not static but dynamic and context-dependent. The findings suggest that these processes reflect not the degradation of the literary language, but its adaptation to digital discourse.
