This article deals with coherent text questions; analyzing discursive sayings, which are classified as a text unit, in which there is a communicative implementation of the grammatical sentence. The basis for the allocation of a discursive utterance in a separate communicative unit is the coreference (communicative-functional equivalence) to a grammatical sentense. Discourse statements with the actualized prepositional interrogative component and their relation to the grammatical formal-elementary (simple) sentence are studied in detail.
