The dynamics of the semantic field “purity” in the context of digitalization: a diachronic analysis based on data from the NCRL

this article explores the dynamics of the semantic field "purity" in the Russian language under the influence of digitalization and internet discourse. The aim of the work is to identify and analyze specific changes in the structure and content of this field at the turn of the 20th–21st centuries. To achieve this goal, a diachronic analysis was applied based on data from the National Corpus of the Russian Language (NCRL), including corpora of Soviet journalism, blogs, and social media. The research tasks included reconstructing the historical evolution of the field, identifying new meanings and semantic nuances actualized on the internet, and determining the role of the online environment as a catalyst for semantic transformations. The study found that internet discourse has led to a reduction in the sacral and moral component, an expansion of ecological semantics, the formation of a digital microfield (e.g., "clean code," "digital hygiene"), hybridization of meanings, and changes in antonymic relations. The practical application of the research results is seen in the fields of linguistic expertise, teaching Russian, as well as in digital marketing and communications for more precise audience targeting.
