Аннотация:This article discusses some antinomies in the category of the verbal aspect in the Russian language, generating contradictions in the aspect theory. The main attention is paid to aspectual pairs of verbs in the Russian language (Slavonic background). We focus on antinomies of different ways of expressing aspectual semantics of verbs (lexical, grammatical and word-formation), as well as on rules for the use of perfect and imperfect verbs and inventory of forms to implement the rules. Our study confirmed the need for distinguishing between lexical and grammatical limits of action in the theory of Slavic aspect. It’s very important also to preserve the concept of aspectual pairs which is organizing paradigm of verbal aspect in Slavic languages.
Key words: Slavic aspect, aspectual pairs, antinomies
