Abstract

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.
