Understanding Referring Expressions in Semantics

This introduction to semantics explores referring expressions, which are used to denote specific referents in context. The discussion includes the distinction between indefinite and definite noun phrases (NPs), and how context affects reference. Examples illustrate the use of proper names, pronouns, and the ambiguity that can arise, as well as opaque contexts where substitutions affect meaning. We’ll cover equative sentences demonstrating that different expressions can refer to the same entity. Delve into how language helps us identify and communicate about the world around us.

  2. Referring expression • Definition • An expression used to refer to a specific referent (something or someone) in mind.

  3. The same expression can be a referring reference or not, depending on the context. • The indefinite NP • A café in the neighborhood is giving away free coffee today. (+R) • The popular image of Paris today is a café. (-R)

  5. Opaque context • Part of an expression can be substituted and the substitution produces different meanings in a given situation. • Imagine that it’s a blank check. The check is an opaque context. You can cash in the amount of money you write. • John believes that _______ is the best café in town. • John believes that Starbukcs is the best café in town. • John believes that Seattle is the best café in town.
