The notion of context is essential to the pragmatic study of language. It is generally considered as constituted by the knowledge shared by the speaker and the hearer. Various components of shared knowledge have been identified, e.g. knowledge of the language they use, knowledge of what has been said before, knowledge about the world in general, knowledge about the specific situation in which linguistic communication is taking place, and knowledge about each other. Context determines the speaker’s use of language and also the hearer’s interpretation of what is said to him. Without such knowledge, linguistic communication would not be possible, and without considering such knowledge, linguistic communication cannot be satisfactorily accounted for in a pragmatic sense. The meaning in pragmatics is concrete and context-dependent. It is the realization of the abstract meaning of a sentence in a creation situation of communication, or simply in a context.
