In a series of complex study of multicomponent or polypredicative complex sentences, it is relevant to consider them as a microtext. In the text study discussion issues still exist: the number and composition of categories, the means of their expression, the difference between the concepts of “textual characteristic” and “text-forming function”. Based on the material of multicomponent complex sentences, we consider universal text categories inherent in any text, and optional, inherent only to certain types of text. The principal categories of the text, such as cohesion, coherence, integrity, consistency, continuum are realized even within the limits of a microtext-sentence. The analysis of multicomponent structures is carried out in a triune way: taking into ac-count the relation of their form, meaning and function. We show that the sequence of homogene-ous subordinate clauses is determined by their content and the communicative task of the state-ment. In this regard, as the utterance unfolds from one subordinate clause to another, either the concretization of the meaning of conditionality or its intensification is revealed. On the other hand, the connection to the subordinate clauses of constructive conjunctions and lexical actualizers contributes to the expression of the category of informativeness, which implies the reflection in the text of the degree of novelty or significance of information. On the example of contaminated structures with various types of communication (compositional, subordinate, non-union), various methods and techniques are described as tectonic means of text formation. Thus, we conclude that a multicomponent complex sentence, which is a transitional structure from a complex sentence to a text, makes it possible to study the interaction of lexical and syntactic means in the formation of the meaning and implementation of the author’s communicative intention.
