Notional Agreement Variability as a Reflection of Role Relations in the Family noun clause

The article examines the reasons for, the character and the patterns of variability of the number forms of predicate verbs with subject nouns having the semantics of compositionality. The sentences with clauses on the basis of the prototypical group noun family, whose semantic relations with the verb component are discussed in terms of case grammar, have been chosen as the object of the study. The conclusions are made on the basis of the quantitative and qualitative analysis of the lexeme’s contextual use examples from the British National Corpus.
