Making some progress on the progressive aspect zài in Mandarin Chinese

Taking into account data hitherto neglected, this article examines the progressive aspect zài 在 in Mandarin Chinese and related issues. We argue in favour of the constituency [ AspP zài 在 [V-zhe 着]] and demonstrate important syntactic and semantic differences between the progressive aspect zài 在 and the durative aspect -zhe 着 . Importantly, unlike ‘zài 在 V’, ‘V-zhe 着’ is only acceptable as the sole predicate in a root sentence when interpretable as a (derived) state. Otherwise, the presence of the progressive aspect zài 在 is required: ‘zài 在 V-zhe 着’. This crucial role of zài 在 is often obscured by its phonological fusion (haplology) with the preposition zài 在 ‘at’ heading an immediately following prepositional phrase: NP [ AspP zài 在 [ VP [ PP zài 在 NP] [V-zhe 着 NP]]] => NP ZÀI 在 NP V-zhe 着 NP. The presence/absence of an underlying progressive aspect zài 在 (having fused with the preposition zài 在) is reflected in the choice of negation. Since the progressive aspect zài 在 must be negated by méi 没, not bù 不, it follows that no underlying aspectual zài 在 is present when it is bù 不 that negates a VP with a zài 在 PP adjunct NP bù 不 [ VP [ PP zài 在 NP] VP]. By contrast, when there is an underlying aspectual zài 在, the negation méi 没 is required, resulting in the surface sequence ‘NP méi 没 ZÀI 在 NP VP’. Finally, given that a subset of auxiliaries, some stative verbs as well as state-denoting ‘V-zhe 着’ are negated by méi 没, negation of ‘zài 在 VP’ by méi 没 is compatible with the status of ‘zài 在 VP’ as a state, hence able to be true at a moment.
