 In Linguistics, ‘context’ commonly means the previous and subsequent linguistic material in a given text. In Kaplan’s scheme, the context is objective, it comprises the actual basic facts about an utterance: the speaker, time, place, and possible world in which it occurs. In Stalnaker’s scheme, context is basically subjective: a matter of common ground: that is, shared beliefs that serve as common presuppositions for the interpretation of assertions. Often the term is used for anything in the indefinitely large surrounding of an utterance, from the intentions of the speaker to the previous topics of conversation to the objects discernible in the environment.
