.It is contextual considerations that make the difference between structural linguistics and sociolinguistics, pragmatics and discourse analysis.J.R. Firth (a linguist) expounded this study and in his contextual theory of meaning argues that context is the bedrock of any linguistic enterprise because "normal linguistic behaviour as a whole is meaning effort, directed towards the maintenance of appropriate patterns of life" (Firth 1957: 223). Since every utterance occurs within a "culturally determined context of situation" meaning is tied to that context about the speaker and the ways he perceives himself,
his roles in the society and his relationship with other members of the society.As pragmatics investigates context-based meaning it will be impossible to talk about pragmatics without reference to the context in which utterances are made.Context refers to the situation, within which language functions.
