language categories in russian morphology

when studying russian morphology, one can distinguish two categories. these categories are “grammatical” and “lexico-grammatical”. grammatical categories can be specified through a series of grammatical features of words. considering different criteria, russian grammarians and linguists divide grammatical categories of their language into different types. in determining lexico-grammatical types, in addition to a series of grammatical features, they also consider a series of lexico-semantic features as well. the lexico-grammatical type is determined in the different forms of parts of speech.
