Language is the mode of identity and recognition. Summer learning programs are essential in helping children and young people interact and develop solid ethical bonds in different communities. Current issues related to the linguistic and philosophical nature of socio-ethical vocabulary in terms of diachronic are discussed in the article. Based on the analysis of a large amount of historical and philosophical material, the authors present their interpretation of the formation stages of the vocabulary of ethics as an integral part of the general philosophical vocabulary. However, each time and in each country, the interpretation of ethical concepts and norms, and therefore terms, was of a concrete historical and purely national character. In view of the objectives of this article, we consider it necessary to give a brief overview of the ethics of antiquity and the Middle Ages in order to understand and consider the specific role of ethics in science and practice of later historical eras. The authors hope that adopting pre-communicative activities as a part of the teaching method will be more effective in learning English as a foreign language.
