词条 | Defeasibility |
释义 |
In pragmatics, a subfield of linguistics, it refers to the fact that certain kinds of implicitly conveyed information such as conversational implicatures and presuppositions can be "defeated" without sounding contradictory. For example, "This flag is green" normally implicates that it is completely green; but "This flag is green. It contains a red disc" is no contradiction. Likewise, "John never stopped smoking" normally presupposes that he used to smoke (and still does), but you can say "John never stopped smoking because actually he never did smoke" without contradiction.[2] See also
