This article discusses the lexical features of Victor Hugo's novel "The Hunchback of Notre Dame." A general description of the vocabulary of Victor Hugo's novel "The Hunchback of Notre Dame" represents an outstanding example of the artistic language of French Romanticism. The work's vocabulary serves not only as a narrative tool but also as a tool for creating a complex poetic structure, in which every word carries semantic, emotional, and symbolic weight. The narrator's speech is dominated by archaisms, rare poetic expressions, and ecclesiastical terminology, creating an atmosphere of the medieval era and enhancing historical authenticity. For example, when describing the cathedral, the author uses words with ancient roots and a solemn sound: "sanctuary," "chapel," "transept," and "canopy." These lexemes immerse the reader in the spirit of Gothic space, where architecture becomes a symbol of eternity and spiritual power.
