Sociolinguistic Variation in English and Russian Vocabulary

Lexical variation represents a fundamental structural dimension of human language, wherein speakers select distinct lexical items based on social, regional, professional, and contact-induced factors. This paper presents a comparative sociolinguistic study of lexical variation in Contemporary English and Russian vocabulary following the structured IMRAD methodology. Utilizing qualitative and contextual comparative frameworks, the research analyzes four primary domains: regional dialectal stratification, social and colloquial variation, professional sociolects, and contact-driven lexical borrowing. Particular attention is paid to the contemporary Englishization of Russian vocabulary, which creates complex synchronic variant sets. The findings demonstrate that while English variation is heavily grounded in historical regional dispersion, Russian variation is rapidly reshaped by intensive contact with global English alongside internal register shifts.
