Many people follow Grice in thinking that all conversational implicatures are cancellable. And often enough, they use this insight as a test for conversational implicatures. If you want to find out whether something is a conversational implicature, the test has it, you should ask yourself whether the thing in question is cancellable; if you find that it is not cancellable, you can infer that it is not a conversational implicature. If you find that it is cancellable, you can infer that (...) it might well be a conversational implicature and that you should now do further testing. Various philosophers and linguists have questioned the test however. Some have held that Grice's cancellability claim is subject to counterexamples and that the test is not reliable. Others have argued that even though Grice's claim can be defended against the examples in question, the test is not as informative as people have hoped. This article provides an overview of the recent discussion on the cancellability test and suggests a way forward. (shrink)

Cancellability is an essential feature of implicatures. However, its reliability has been challenged by several cases and examples in which conversational implicatures seem to be hard or even impossible to cancel. Should it then be concluded that not all implicatures are cancellable, and therefore Grice's cancellability test should be weakened or abandoned? The present paper addresses this problem by drawing a distinction between theoretical and practical cancellability, where the latter concept captures the (un)reasonableness of explicit or contextual cancellation. By analyzing (...) three legal cases of misleading advertising, I show how the indefensibility of an interpretation can account for the practical uncancellability of an implicature. To explain and account for the reasonableness of an interpretation, the presumptive inferences involved must be reconstructed and evaluated considering different dimensions, such as the conversational context and the associated presumptions.
