 So, when a speaker appears to have violated a maxim by saying or making as if to say something that is false, uninformative or too informative, irrelevant, or unclear, the assumption that the speaker is in fact obeying the maxims causes the interpreter to infer a hypothesis about what the speaker really meant.That an interpreter will reliably do this allows speakers to intentionally "flout" the maxims—i.e., create the appearance of breaking the maxims in a way that is obvious to both speaker and interpreter—to get their implicatures across.Perhaps Grice's best-known example of conversational implicature is the case of the reference letter, a "quantity implicature" (i.e., because it involves flouting the first maxim of Quantity)
