Presuppositional Exhaustification

Grammatical theories of Scalar Implicatures (SI) make use of an exhaustivity operator EXH, which asserts the conjunction of the prejacent with the negation of excludable alternatives. We present a new Grammatical theory of SI according to which EXH is replaced with P-EXH, an operator which asserts just its prejacent, and *presupposes* the negation of excludable alternatives. We show that this theory resolves a number of empirical challenges faced by the old formulation of EXH (as well as by non-grammatical, Gricean theories of SI). The empirical issues include oddness-inducing implicatures (Magri 2009), the behavior of SI under negation, and an old SI puzzle originally due to Chierchia 2004 (called here the "some-under-some" puzzle), which proves challenging for existing SI accounts.
