The argument here comes from consideration of a certain sort of linguistic expression called negative polarity items (NPIs). These are expressions such as “any,” “at all” and “ever.” NPIs are of particular interest for semantics because they can only be used in contexts with a certain rather abstract semantic feature. However, the precise characterization of the feature is itself a matter of some controversy. For those interested in the semantics of natural language it is worthwhile to figure out precisely what (...) this feature is. Once we have an account of it, we can use the account to infer facts about the meanings of various expressions that interact with NPIs. (shrink)

A downward-entailing context has the property that the replacement of the predicate in the context by a stronger predicate preserves truth. So, for instance, presuppositions aside, the context after “every” in (1) where the NPI “ever” appears is downward entailing.

Yang (2004) observes that in Mandarin, an initial possessor phrase (PossessorP) may be followed by a bare noun as in (1), or by a possessee phrase that can be headed by a numeral and classifier, [Numeral + CL + N], as in (2) or by a demonstrative, [Dem + (Numeral) + CL + N] as in (3). (In all the examples in this section, we begin with Yang’s own initial glosses and translations3. The interpretation of the examples will be probed (...) after they have been presented.). (shrink)
