Explicature

Explicature is a technical term in pragmatics, the branch of linguistics that concerns the meaning given to an utterance by its context. The explicatures of a sentence are what is explicitly said, often supplemented with contextual information. They contrast with implicatures, the information that the speaker conveys without actually stating it.[1]

The truth value of a sentence is determined using its explicature.[2] For example:

Imagine Jim and Raoul are driving across America from New York City to Seattle, Washington. Raoul is driving, and Jim falls asleep. When Jim wakes up, he asks Raoul, "Where are we?" Raoul replies, "We aren't there yet, but we've passed Chicago."

If Jim and Raoul's car is in fact five minutes outside Seattle and Raoul knows this, he may be accused of lying, since "We aren't there yet, but we've passed Chicago" in that context has the implicature "We are not too far past Chicago and still not near Seattle." Technically, however, Raoul's statement was true, because the explicature — at the time of utterance, Jim and Raoul had passed Chicago and were not yet there (supplement: in Seattle) — was true.
