Nonfamiliarity and indefinite descriptions

Abstract

Kehler & Ward (2006) argue for the existence of NONFAMILIARITY IMPLICATURES, including one that results from the use of English a/an rather than the. This implicature appears intended to subsume the scalar implicature of nonuniqueness postulated by Hawkins (1991). In this paper we try to clarify the nature of such a nonfamiliarity implicature, and we present evidence that such an implicature does not supplant Hawkins's nonuniqueness implicature for indefinites.
