Language as a complex unity consists of language and speech and the levels of norms that connect them. Linguistic units are connected in speech not only on the basis of sequence, but also under the influence of pragmatic factors, the specific situation and environment of speech, the state of the speaker and the listener act as a factor that characterizes the linguistic unit.\n\nAs any linguistic unit occurs in speech, first of all, its general linguistic essence is determined by other adjacent linguistic factors. In particular, the sememas of polysemantic lexemes differ under the influence of morphological and syntactic levels and “prepare” for occuring in speech. The speech situation gives it additional nuances, sometimes when morphological and syntactic (linguistic) factors are "weak", their function is taken over by pragmatic factors - linguistic factors are accompanied by pragmatic (pragmatic) factors.\n\nWhile any morphological form occuring in speech, the semantic essence of the lexeme it forms (lexical factor), the other word form (syntactic factor) combined with the formed word play an important role. But these factors can never occur without a pragmatic factor - they cannot be free from it.\n\nSince speech has a systemic (integrity) nature, its components are also of a systemic nature. There is a social need for the formation of a new linguistic direction specializing in the systematic study of the interaction of linguistic levels and pragmatic factors, which have a nature of systemic construction, in the process of formation and expression of thought, the consistent and vivid systematization of each component of speech.
