BOUNDARIES BETWEEN WORD-FORM BUILDING AND INFLEXION AS A MEANS TO DEVELOP GRAMMAR SKILLS OF STUDENTS IN THE MODERN RUSSIAN LANGUAGE

This study deals with one of the most important, yet not entirely understood issues of Russian grammar, which is identifying boundaries of form building and inflexion in the modern Russian language. We determine the main boundary characteristics of grammaticality and define the types of formedness. The language system is studied in terms of levels improving the faculties of students: word form → form building → word building → inflexion. Formal semantic potentials of morphology and syntax are considered as grammatical stimuli raising linguistic competence of students.
