The book represents, in parts 1-4, results of the author's more than 30 years of studies of the Russian language. These parts deal with: 1) Semantics and lexicography (in particulary, the "Explanatory Combinatorial Dictionary of Modern Russian"); 2) Syntax; 3) Phraseology; 4) Morphology (derivation and inflection). Part 5 is dedicated to linguistic work of A.A. Reformatskij and R.O. Jakobson. (Kar)
