The Science: Social Sciences: Linguistics: (Sociolinguistics Linguistics )

Sociolinguistics is the study of the relationship between linguistic behaviour and social situations, roles, and functions. Rather than concentrating on individuals, sociolinguistics is centered on the speech community; defined as any group of people who share some set of social conventions, or sociolinguistic norms, for language use. This relationship between language and society encompasses a wide variety of social situations--from international relations to interpersonal relationships.
