The naming of professions and job titles reflects not only linguistic norms but also social structure, cultural values, historical development, and gender ideology of a society. This article examines the specific features of professional and occupational naming systems in the Russian and Uzbek languages. Special attention is paid to morphological, semantic, grammatical, and sociolinguistic aspects of profession names, including gender marking, borrowing processes, word-formation models, and modernization trends. A comparative analysis reveals both shared characteristics and significant differences conditioned by typological distinctions between the Slavic and Turkic language families. The study demonstrates that professional nomenclature functions as a dynamic linguistic subsystem closely connected with societal changes.
