So, Sang-Ho. 1998. The Conversational Condition and Scalar Implicature. Studies in Modern Grammar 13, 133-156. The purpose of this article is to reveal the explanatory power of the Conversational Condition on Horn scales proposed by Matsumoto(1995). Quantity implicatures are divided into two specific and important sub-cases: scalar Quantity implicatures, and clausal Quantity implicatures. The recognition of such scalar implicatures not only aids the understanding of the semantics of the general vocabulary in a language, but it also plays a crucial role in understanding the logical expressions in natural language, specifically the connectives, the quantifiers and modals. The clausal implicatures explain that the use of disjunction rather conveys that one has grounds for believing one or the other disjunct but does not know which. Whatever the correct semantic analysis of conditionals is, a number of troublesome features can be accounted for by means of implicature. One crucial notion in the Conversational Condition is that of an information-selecting maxim. This is the maxim that influences the choice between S and W. There are three subinstances of the Conversational Condition: the Quantity-2 Condition, the Relevance Condition, and the Non-obscurity Condition. The Conversational Condition can give a unified account of quite a wide range of examples involving the production and non-production of Quantity-1 implicatures.
