This study examines the novel Taghribat al-Qafir by the Omani novelist Zahran Al-Qasimi, winner of the International Prize for Arabic Fiction (Booker) in 2023, focusing on a central analytical axis: the hybrid narrative language that blends Classical Arabic with endangered Omani local vocabulary, as a tool for reshaping cultural identity. The study seeks to trace the features of this language and its mechanisms of formation within the novelistic text, as well as how local vocabulary transforms from mere descriptive tools into semiotic and symbolic signs bearing profound existential connotations. The analytical efforts of this study are distributed across two main axes: the first addresses the duality of narrative language between eloquence and locality as a paradigm for identity, highlighting how Al-Qasimi reproduces the Omani "habitus" in a living narrative fabric through the employment of terms such as al-Qafir, al-Tawi, al-Ghayl, and al-Sa'id. The second axis, meanwhile, focuses on analyzing local vocabulary as tools for deconstructing reality and accumulating existential and symbolic connotations, concentrating on how these terms have transformed from material descriptions into icons for the great questions of life, death, fate, and alienation. The study concludes that Al-Qasimi thereby establishes a unique model of Omani magical realism that emerges from the local geography, rather than importing Western or Latin American models, where the marvelous merges with the everyday through a narrative language that presents the supernatural as ordinary facts.
