Abstract
Linguists and philosophers have traditionally argued that definite constructions presuppose familiarity on the part of the addressee. This article examines empirically the question of what kind of familiarity, in the context of newspaper editorials, this might be. A significant issue, articulated by literacy theorist Walter Ong, is the nature of the reader and whether a writer can know what a reader is familiar with. Taking a case study approach, the author examines definite constructions in 15 editorial articles from the Christian Science Monitor. These constructions are classified, following Brown and Yule (1983), as either re-evoking, new, or inferrable. It is argued that for purposes of studying the writer-reader relationship, the inferrables are most interesting since they indicate what the writer believes the reader is capable of inferring. Ultimately both the new and the inferrable show that writers use definite constructions in accord with genre conventions. The author concludes that such conventions make communication efficient.
