The article examines the linguistic mechanisms underlying the conceptualization of the “anomalous world” in contemporary English-language literature. The study explores how linguistic structures, cognitive models, and semiotic strategies contribute to constructing fictional realities that transcend the boundaries of natural and cultural norms. Drawing on the theoretical frameworks of cognitive linguistics, literary semiotics, and discourse analysis, the research highlights the interaction between linguistic form, conceptual content, and aesthetic function in the process of world-building. Through the analysis of works by J. R. R. Tolkien, J. K. Rowling, and Neil Gaiman, the paper demonstrates that the anomalous world functions as a dynamic linguistic and conceptual construct, integrating mythological, symbolic, and cultural codes. Lexical innovations, metaphorical extensions, and syntactic patterns act as key mechanisms of meaning formation, shaping the reader’s perception of fictional reality. The findings emphasize that language not only reflects imaginary worlds but actively constructs them, transforming linguistic creativity into a fundamental tool of cognitive and artistic representation.
