“ Semelfactive ” - no ̨ - and the Western Aspect Gestalt * Stephen

This article presents a discussion of differences between the Slavic languages regarding the historical productivity of -no ̨as an aspectual suffix. It is shown that a class of prefixed pf a-stem/n-stem doublets has been more productive in a group of western languages (primarily Czech, Slovak, Upper Sorbian) and that this productivity declines in the languages farther to the east, reaching a minimum in Russian and Bulgarian. Further, differences are shown regarding the function of -no ̨as a perfectivizing suffix in some Common Slavic unprefixed pf verbs. These differences are then discussed, with no claims to an exhaustive analysis.
