This examines the specifics of linguistic tools functioning as instruments for shaping and expressing cultural identity in the works of the prominent Quebec writer Jacques Godbout. The study primarily focuses on a comparative analysis of the author’s landmark works: the early novel “Hail Galarneau!” (1967) and the later work “The Concierge of the Pantheon” (2006). The theoretical framework of the analysis is based on Lise Gauvin’s concept of “linguistic hyperconsciousness” (surconscience linguistique), which views the language of a Francophone writer in a different cultural environment as an object of constant reflection and conflict. The analysis traces the evolution of Jacques Godbout’s authorial strategy: from the active use of “joual” and neologisms as instruments of socio-political resistance during the Quiet Revolution to a subtle, ironic play with linguistic norms in the heart of the metropolis — Paris. The study demonstrates that in the novel The Concierge of the Pantheon, language transforms into an independent character, embodying the author's linguistic hyperconsciousness. Through the prism of Pierre Léon’s semiotic model of phonostylistic analysis, the research identifies the role of linguistic “indicators” (involuntary markers of origin) and “signals” (conscious markers of otherness) in the speech of the protagonist, Julien Mackay. Special emphasis is placed on the interweaving of professional meteorological discourse (“des tempêtes d’amour”, “spécialiste des orages domestiques”), Quebec dialectaisms (“bout d’criss”, “l’air cheap”), and anglicisms-calques (“tomba amoureux fou”, “ces cahiers made in France”, “Gibert Jeune est un self”). It is established that by employing markers of the hero’s geographical and mental affiliation within the context of “flawless” Parisian French, the author creates an effect of “detonation.” The scientific novelty of the paper lies in determining the mechanisms of transforming “linguistic hyperconsciousness” into an act of linguistic resistance, where irony serves as a key tool for deconstructing the myth of the monolithic academic norm. The study concludes that Jacques Godbout’s oeuvre represents the complex trajectory of Quebec literature: from the struggle for self-identification to integration into the global Francophone context through the preservation of its own linguacultural uniqueness.
