“…In order to explain this distribution, we advance the hypothesis that the bare mass and the bare singular both denote kinds, derived from a set denoted by an abstract root noun via a lexical operation. Bare plurals denote plural count predicates which, following Krifka (2004) shift either to a kind-denoting expression or to an existential generalized quantifier. We show that the bare mass and the bare singular are identical from a grammatical point of view, and that, as expected on this theory, they behave in the same way in other respects, including selection by mass quantifiers and interpretation in comparatives.…”
