 Whereas semantic implicatures are generally entailed by what is said, many believe that conversational implicatures cannot  be.[15]  As  (1),  (2),  (5),  and  (6)  illustrate, conversational implicatures are typically not entailments. But exceptions have been  observed.[16]  When a speaker gives an affirmative answer to “Did you drive somewhere yesterday?” by saying “I drove to Aspen”, what is implicated (“I did drive somewhere”) is entailed by what is said (“I drove to Aspen”). The same is true in hyperbole and loose use  (§4).  Neale (1992: 529) believes the cancelability of conversational implicatures prevents them from being entailments. But while an entailed implicature cannot be explicitly canceled without contradiction (“I drove to Aspen but did not drive anywhere”), it can be implicitly canceled. If a blizzard makes it obvious that no one could have driven to Aspen yesterday, “I drove to Aspen” may implicate that I did not drive anywhere.
