The aim of the study was to identify the semantic features of the representation of the category of security in the French text of Jules Verne’s novel “Les Enfants du capitaine Grant” (“The Children of Captain Grant”). The results show that in Verne’s novel the category of security is verbalized by a set of lexical units, including adresse, apaisement, asile, assurance, calme, confiance, garantie, talisman, tranquillit?, paix, pr?cision, protection, justesse, fid?lit?, franchise, s?ret?, s?curit?, and solidit?. Lexical units expressing the category of security occur unevenly throughout the text. The core of the semantic field is formed by the lexical units confiance and calme. The near periphery includes s?ret?, adresse, pr?cision, protection, tranquillit?, s?curit?, paix, garantie, and asile; the far periphery comprises assurance, fid?lit?, justesse, solidit?, and franchise; and the extreme periphery is represented by apaisement and talisman. The use of lexical units denoting security in the novel is accompanied by a specific set of modifiers and verbs. The verbs display greater variability than the adjectives associated with these lexical units. Most frequently, the author combines security-related lexemes with the adjectives absolue, parfaite, telle, digne, toute, compl?te, and grande, as well as with the verbs avoir, parler, faire, respirer, d?pendre, ?tre, chercher, and trouver. Identifying the lexical features through which the category of security is expressed in “The Children of Captain Grant” makes it possible to gain a deeper understanding of the conventions governing its representation in works belonging to the adventure genre.
