On the structural and semantic correlation of grammatical units of the languages from typologically different systems

The paper deals with the issues of finding out the specific derivational affixes of the lexical units within the grammatical classes of nouns, adjectives, verbs and adverbs in the Orok language. The formation of the lexical units within each class allows to build up an inventory. The analysis of the morphological and semantic structures of the word and word form of the languages com-pared reveals an analogy between a number of Orok language morphemes and Russian language lexical units, i.e. the equivalence of the Tungusic word to the Russian word phrase. In fact, the Orok derivational unit the suffixal morpheme is equivalent to the Russian lexeme and the Orok lexical unit – to the Russian syntactic unit.
