Abstract
Abstract The peculiarities of speech etiquette in each language are determined by historical, cultural, social, cognitive, and religious factors. The study of greeting and farewell speech formulas in Turkish and Arabic is relevant for identifying key linguacultural meanings and concepts using conceptual modeling. The purpose is to analyze the linguistic and cultural conditioning of etiquette formulas in these languages. Linguacultural analysis of linguistic facts was used, along with elements of conceptual, communicative, comparative, and semantic analysis. The results show that the conceptual structure of etiquette formulas consists of functional-semantic fields like temporality, religiosity, marking conversation beginnings/endings. In Turkish, temporal concepts like “day” and “morning” are most frequent, while in Arabic religious concepts like “Allah” and “peace” prevail. Similarities include polite treatment of interlocutors, adherence to religious traditions, and hospitality. Differences lie in the degree of metaphoricality, imagery, and extended responses. The conclusions form ideas about the interrelations between core and peripheral linguacultural concepts, linguistic diversity, and invariance of etiquette formulas, their cognitive representation and role in shaping linguistic personality. The study contributes to understanding national mentality through the analysis of speech formulas.
