The interaction of idioms and aspect in Polish

Abstract This study contributes to a longstanding discussion on the status of aspectual morphology and architecture in Slavic by investigating properties perfective imperfective VP idioms Polish. The investigation reveals that only lexical prefixes which can result idiosyncratic meanings are part basic idioms. Building idea little v is demarcation line for idiomatic meanings, it concluded P-internal. It also shown compatible with some superlexical secondary morphology, suggests such P-external. Further semantic analysis interaction different classes shows ones measure over scale associated P-external material or temporal trace an (idiomatic) event. In contrast, incompatible encoded verbal predicate impose restrictions its argument hence they intervene semantics idiom. Based stacking facts two distinguished: high (projected above imperfective) low below it). These observations view separated from PFV IPFV operators. former may merge lower hierarchy, latter act at level AspP as phonologically null
