О векторе развития русской морфологической системы

The article presents a fair judgment on scientifically established statements about strengthening of analytical trends in the grammatical base of the Russian language, about co-realization of standard grammatical categories of word form changeability in a pair with dynamic growth of word classes with the unchangeable paradigm of word forms. The diachronic approach and retrospective method of analysis helped collect the facts from the history of Russian grammar and check vectors of grammatical system development, which gave the way for refuting the statement about the diachronic stability in the system of form changeability in grammatical classes of words. It is stated that Russian has kept and is still developing a synthetic trend, which is supported with special formal means. It is proved with the samples that point to the growth of synthetic ways in grammatical meaning realizations.However, the author highlights some novel trend in part of speech constriction, that is, new grammatical categories, non-standard means in grammatical meaning representation, in particular, the appearance of complex synthetic language forms that demonstrate co-inclusion of analytical and form-building features in the Russian word paradigm. Deep consideration of the facts stated in the articleresults in the conclusion that a trend of compound grammatical co-realization can’t be called a general vector of morphological system development towards analytical form building, it’s one of the way that is registered in grammatical system of the Russian language.
