Global Positive Polarity Items and Obligatory Exhaustification
I argue for a distinction between two types of positive polarity
items (PPIs) which has not been recognized so far. While for some PPIs,
anti-licensing is a strictly local phenomenon, for other PPIs anti-licensing
should be stated as a global condition.
I aim to contribute to a principled explanation for the distribution of a
significant subset of global PPIs, by relating it to specific semantic properties
of the relevant items. More specifically, I argue that PPIs such as soit . . . soit
. . . , quelques and almost trigger obligatory exhaustivity effects and scalar
inferences, and that independently motivated constraints regarding the
generation of such inferences can account for their distribution. The paper
also briefly addresses the case of other global PPIs, e.g., at least, for which a
similar account is not straightforwardly available.
