Observation: The predicates in (1) are all activity predicates, whereas those in (2) denote accomplishments or achievements. The expectation is that ngưng could also be used with the latter predicates as well; however, as in English, it should imply that the activity has stopped before completion (i.e. is temporarily suspended). Could someone please provide relevant examples?
Query: If these examples are representative, rather than a sampling error, they suggest that predicates to do with true telicity always appear postverbally, whereas 'quasi-aspectual predicates' that simply mark the edge (beginning or end) of an event (Travis' Outer Aspect?) appear preverbally. I have a sense that the syntactic options for the pre/post-verb lại bear this out. Does this seem to be on the right track?
