Derivational nest as system and categorical organization of cognate words

Grammatical centric conception of the language dates back to the traditions of the description of morphology and word formation as a single holistic object. At the general categorical level the derivational nest represents a paradigmal language formation demonstrating natural interrelations between the parts of speech. Derivational nest acts as hyperparadigm which includes the entire amount of structural components (subparadigms) as well as the tops of the nests.
