The purpose of the study is to trace the changes in the meanings of the dominant verbalizers of the ethical concepts “Love,” “Mercy,” “Chastity,” “Virtue” and to determine the impact of these changes on the linguistic and cultural consciousness of modern native speakers. The authors used comparative-historical method, E.M. Vereshchagin, V.G. Kostomarov’s method of allocating semantic shares, questioning, cognitive interpretation, etc. The research was conducted on the material of explanatory dictionaries of the Russian language of different periods and the Church Slavonic language, associative dictionaries and data from sociolinguistic surveys. The article defines the ethical semantic shares of these concepts, establishes their connection with the Orthodox worldview. The ideas of modern students about the selected ethical concepts are studied, transformations in their understanding and evaluation are indicated. © Dmitriyeva N.M., Chulkina N.L., 2022.
