The delimitative prefix 'po-', durative adverbials, and Slavic aspectual composition

The paper examines perfective verbs with the delimitative prefix po- (podel) combining with durative adverbials (DurAds) in Slavic, primarily based on examples from Serbian. Since DurAds are standardly assumed to diagnose atelicity, such examples constitute the main argument for separating Slavic perfectivity from telicity (e.g. Borik 2006), and pose the major obstacle for the view that perfectives in Slavic are telic (e.g. Łazorczyk 2010). I propose that DurAds are generated in the QP (a telicity projection), while podel combines with the QP, specifiying a telic predicate for singularity. Consequently, all prefixed perfective verbs in Slavic are necessarily telic.
