The article characterizes the communicative and formal-grammatical structure of sentences with quantity predicates of the type ЇХ БУЛО СІМ. Ukrainian linguists divide such sentences into genitive subject and numeral predicate, taking into account the semantic and positional criteria (left-handed subject, quantitative predicate).
The author of the study differentiates aspects of sentence organization by criteria: intonation-positional means (communicative aspect), syntactic connections (formal-grammatical aspect).
Communicative analysis shows that such sentences are one of the options of sentence implementation in speech. In the communicative paradigm of a sentence they relate to an articulated and contextually dependent type of utterance (complex theme – genitive noun and verb – denote given, rheme – numeral – denotes new). Numerous examples of sentences with the same morphological set of words (independent numeral, dependent noun, verb) show the relations between members of the communicative paradigm of the sentence; the question of specificity of semantics of noun and verb components is considered.
Formal-grammatical analysis reflects the structure of a two-member sentence that combines a complex subject (an integral connection of the main nominative-numeral and the dependent genitive-noun) and a simple verb predicate (conditional-grammatical agreement with the subject).
The communicative structure of the sentence is derived, because it was formed as a result of rupture of the complex subject and transfer of the genitive noun to the initial position of the sentence-utterance.
Conclusions about the asymmetric nature of relations between different levels of articulation of this type of sentence-utterance were made.
