The aim of the paper is to identify and describe the main structural types of the lexical meanings of the autonomous words. These types are distinguished according to the modes of their inner organization, but not in dependence upon the character of signified objects. It has been established that there exist as a minimum six semantic types of the autonomous words: descriptive, comparative, deictic, anaphoric, criterial-evaluative and relational. The main research methods of immutable lexemes of complete value in modern Russian were: functional analysis of the relevant linguistic material system, obtained by continuous sampling of written sources (dictionaries of neologism, modern newspapers, magazines, fiction), as well as speech Conversational and online publications. The relevance of the topic of this study is due to the fact that, despite the growing interest in this problem, no description has yet been created of a new, unchanging vocabulary that would take into account modern language processes and would reveal the developmental trends in the development of the morphological system of the Russian language.
