The notion «natural classification», known as the general theory of cognition, presupposes an orientation to the relationships presented in the object of analysis, which are characterized by elements of heterogeneity. The chapters within the monograph deal with the problems of natural classification, lexicon-grammar interaction, classification of various types of utterances, typological analysis of grammatical forms and constructions. A dedicated part of the book examines natural classes in child speech. All chapters of the collective monograph present an analysis of both systemic (language-specific) and speech properties (principles and characteristics) of natural classification and this analysis is connected with both theoretical and real problems of Functional Grammar.The monograph is addressed to linguists interested in the theory and methodology of grammatical research as well as the analysis of debatable problems of the morphology and syntax of Russian and a number of other languages
