Abstract
This article discusses the concept of lexical and semantic groups. In the article, the author analyzed the basic principles of the formation of lexical and semantic groups, their role in lexicography and linguistics, as well as methods for their definition and classification. Practical examples of lexical and semantic groups for the study of linguistic phenomena and categories were considered. The article discusses the prospects for additional study of lexical-semantic groups and their significance in understanding the organization of lexical material in the language. The article will be devoted to teachers and students working with difficulties encountered in the analysis and interpretation of lexical and semantic groups in different language contexts.
