Anaphora, accessibility, and bridging

Dynamic theories of discourse interpretation seek to describe and explain antecedent-anaphor relations with the help of discourse referents. In a dynamic framework, it is the function of indefinite expressions to intro-duce new discourse referents, whilst anaphoric expressions serve to retrieve them. Dynamic theories provide a simple and intuitively appealing solu-tion to a variety of problems. For instance, they explain how it is possible for an indefinite expression to “bind ” a pronoun that isn’t c-commanded by it, as in (1a,b), and why examples like (2a,b) are infelicitous: (1) a.
