Draft additions March 2003 scalar implicature n. Linguistics (of a gradable term or construction) an implicature that no stronger value can truthfully be used; the use of a relatively lower-valued term to implicate that no higher value is true. ΚΠ 1972 L. R. Horn On Semantic Properties of Logical Operators in Eng. (Ph.D. diss., UCLA) 96 Both John and Bill didn't go (just one of them)... Notice that the implicit continuation we have filled in above is simply a scalar implicature: not all implicates not none, i.e. some. 1985 Language 61 771 The negative quality which Cutler attributes to this example does not result from FR [sc. fall-rise intonation], but rather from the scalar implicature which A is entitled to infer from B's response—i.e., that the higher value good is false or unknown to B. 1999 Jrnl. Aesthetics & Art Crit. 57 379/2 If a narrator described two characters as ‘engaged’ then, in accordance with the phenomenon of what linguists call scalar implicature, the reader can assume as a fictional fact that these two characters are not already married, even though the narrator does not explicitly say so.
