B??, translated most often in Russian linguistic texts as aspect, is one of
the grammatical categories of verbs in the Russian language. B?? manifests the process of an action from the resultative or inresultative, continuity or incontiuity and so on point of view. B?? is formally expressed by some morphological instruments such as suffixes and prefixes inside the finite form of verbs, in the Russian language ac?eKT, being a functional- meaningful category, just as B?? may express the process of an action. However, it is able to be expressed not only by morphological instruments but also by other instruments such as syntactic instruments, lexical meaning.
