Abstract
<jats:p>Fantasy literature relies heavily on linguistic creativity to construct imaginary worlds that appear coherent, immersive, and believable to readers. Among contemporary fantasy authors, J.K. Rowling has achieved remarkable success in creating a detailed magical universe through the effective use of language and stylistic techniques. This study investigates the role of stylistic devices in the construction of fantasy worlds in J.K. Rowling’s Harry Potter and the Philosopher’s Stone. The primary objective of the research is to identify the most prominent stylistic devices employed in the novel and to analyze their contribution to world-building, characterization, and the representation of magical reality. The study adopts a qualitative linguostylistic approach and is based on the descriptive, contextual, and interpretative analysis of selected passages from the novel. Particular attention is given to metaphor, simile, personification, epithets, hyperbole, and symbolism. The findings demonstrate that these stylistic devices perform functions that extend beyond aesthetic ornamentation. They facilitate the creation of a distinctive magical atmosphere, provide vivid descriptions of characters and settings, and enable readers to visualize unfamiliar objects, creatures, and phenomena within the fictional universe. The analysis reveals that metaphor and symbolism play a central role in expressing abstract magical concepts, while personification and simile contribute significantly to the portrayal of Hogwarts and other elements of the wizarding world. Furthermore, stylistic devices enhance narrative engagement by strengthening emotional responses and supporting the reader’s immersion in the fictional environment. The study argues that Rowling’s success in fantasy world-building is closely connected with her strategic use of stylistic resources, which transform ordinary language into a powerful tool of imaginative representation. The findings contribute to contemporary stylistic and literary-linguistic research by demonstrating how stylistic devices function as essential mechanisms in fantasy discourse. The results may also be valuable for literary scholars, translators, and students interested in fantasy literature and linguistic approaches to literary texts</jats:p>
