On the grammar of long and short adjectives and participles in Russian.

The paper considers full and short forms of adjectives and present passive participles, forming in Russian syntax the peculiar category of «full form» vs. «short form», which still doesn’t have its adequate grammatical description. The observations are made within the applied functional-communicative linguodidactic model, which conveys theoretical and practical requirements of teaching Russian as a foreign language (hereinafter referred to as RKI).
