ABOUT A FACTOR IN THE RICHNESS OF THE NATIONAL LANGUAGE
The emergence of synonyms, including lexical synonyms, is one of the ways of sources of enrichment of the lexical structure of the language, and the existence of lexical synonym and synonymous series of words is one of the indisputable proofs of the richness of language. The idea and thoughts of famous scientists according to the given problem have written here. Tajik literary language is one of the oldest and richest languages of the world. It has been constantly evolving for centuries. At the same time, the language is constantly evolving, constantly changing, which is primarily associated with the evolution of words - the appearance of new words, obsolescence, changes in the structure, content and position of consumption. In the language system, the leading position of the word is determined, first, by the fact that the most important function of the language is to give the name of the concept and expression of the feelings of the speaker or writer, though. The function of a word can be understood from the fact that it acts, with one side, as a lexical unit, and with another side, as a grammatical unit. When studying the literary language and the assessment of the language and style of poets and writers who master the speech, it is necessary to approach this point of view. The richness and quality of the language and the style of the writer are determined by the fact that he possesses a large number of words, knows the meaning and nuances of the words and their use in the corresponding position. This is also a unique phenomenon in our rhetoric, that the Tajik people, Tajik scholars and writers throughout the centuries have preserved a large number of important words through literature, a large number of dictionaries and their own memory, and a similar memory, and so on. The richness of a language depends, first of all, on the location of lexical units. When studying lexical synonyms, we completely disprove one question: the text plays an important role in determining the semantic and consumer functions of lexical units. It is in the text that become clear semantic and stylistic features of the word, so the text is an indispensable basic stylistic part. The origin of adverbs, including lexical ones, is one of the ways to enrich the lexical structure of a language. The existence of lexical synonyms, series of synonyms of words - one of the indisputable proofs of the richness of the language.
