 Following Sperber &amp; Wilson (1986a: 182), Carston (2004b: 635) later defines an explicature as a development of a logical form encoded by the sentence uttered, and an implicature as any proposition communicated by an utterance that is not an  explicature.[69]  The technical terms “development” and “logical form” are understood in such a way that [15b] is a development of [15a]. Thus understood, “explicature” covers much more than what is said, and “implicature” covers much less than what is implicated as defined in  §1.
