Being progressive is just a phase: celebrating the uniqueness of progressive aspect under a phase-based analysis

摘要

The identity of phasal boundaries has mostly been considered in light of minimal CP-TP-vP-VP structures. The question this paper addresses is where the clause-internal phase boundary lies in light of more complex structures in which aspectual projections intervene between TP and vP. I claim progressive aspect to be unique amongst aspectual forms in English in that it is part of the clause-internal phase, whilst perfect aspect and all higher functional items are contained within the CP/TP phase. This claim accounts for many peculiar quirks of progressive aspect in English, namely in VP ellipsis, fronting phenomena, idioms and existential constructions. On the theoretical front I argue that this division in the aspectual hierarchy is best understood through a variable approach to phases in which the highest projection within a sub-numeration acts as the phase, irrespective of what that projection is. This denies vP of its exclusivity as the clause-internal phase, and allows the progressive layer to project the phase when present. This approach generally sits in line with the move towards a dynamic understanding of phases, as per Bobaljik and Wurmbrand (2005), Wurmbrand (2012, 2013) and BokoviA double dagger (2013, 2014).
