ON THE SECONDARY IMPERFECTIVATION OF PO-PERFECTIVES IN RUSSIAN

The paper deals with a number of characteristics of the secondary imperfectivation of po-perfectives in Russian. The study is based on the analysis of the level of imperfectivability of Russian perfective verbs with the prefix pocompared to a number of other prefixed perfective verb groups (e. g. the verbs with such perfectivizing prefixes as na-, za-, etc.) according to the Dictionary of Russian Language, the Russian National Corpus and the Russian-language Internet (Runet). It is shown that the discussed perfective verb group is specific as a whole as well as with respect to its subgroups, i. e., deperfective perfective verbs and morphologically marked Aktionsarten. Po-perfectives demonstrate a low average imperfectivability in comparison to corresponding figures for other prefixed verb groups. For the subgroup of deperfective (formed from perfective stems) verbs the level of imperfectivability is also unusually low. The delimitative Aktionsart shows
