WORD-FORMATIVE CATEGORY AS A MACRO-UNIT OF A DERIVATIONAL SYSTEM: PLANE OF EXPRESSION
The article aims to build an abstract formal model of a word-formation category by analyzing, systemizing and generalizing the most significant theoretical ideas of the structural-formal features of this macro-unit of the derivational system (on Russian-language material). The following components of a word-formative category are determined: minimal (basic), fundamental and complex (properly structural) substantial units; their system-forming character is clarified. A word-formative category is structured in two projections: paradigmatic (organization model – hierarchical collateral subordination) and syntagmatic (organization model – derivational opposition). The approaches and methods used to investigate the formal-structural organization of word-formative categories are analyzed. The results of this work can contribute to the development of the theory of word formation and to the unification of the description of the system of word formation of the Russian language in cateegorial plane.
