The status of secondary imperfectivization in Polish: Evidence from VP idioms

This paper offers new insights into the status of secondary imperfective morphology and its interaction with different classes of aspectual affixes based on the analysis of their compatibility with basic perfective and basic imperfective VP idioms in Polish. We provide new evidence in favor of the v P-external status of secondary imperfective morphology and we propose a new architecture of aspectual morphology in Polish in which there are two classes of v P-external superlexical prefixes: high and low. The former are projected in several functional projections above secondary imperfective morphology while the latter are projected below it in a single dedicated functional projection.
