This monograph is adding an addition or a word to a word, semantic changes occur. As a result of the activation of certain sema in Semema, some grammatical, pragmatic sema serve to express lexical meaning, and on this basis repeated words are made, in speech some such repeated words become polysemous lexemes. The meaning formed on the basis of a change in the grammatical, syntactic function of a word is sometimes the basis for the formation of repeated words.A compound word is formed on the basis of potential semis of words that do not express some lexical meaning. Also, the semantic narrowing in the expression of such words causes the activation and emergence of ema, and on the basis of these Emas, certain repeated words become a unit of lexical meaning.Even on the basis of repeating the sememes of polysememous lexemes, repeated words are formed. If some of such repeated words are not made, some will be a cardinal word.
