This article offers a profound philological inquiry into the internal organization of the Russian word’s semantic core. Moving beyond traditional descriptions, it explores the "architectonics" of lexical meanings—how they are constructed, layered, and transformed within the linguistic system. Based on the classical heritage of Academician V.V. Vinogradov and integrated with modern cognitive paradigms, the study examines the transition from rigid denotation to fluid connotation. The analysis focuses on the hierarchical dependencies between direct, figurative, and socially conditioned meanings that define the unique expressive power of the Russian Logos.
