sociolinguistics, the study of the sociological aspects of language. The discipline concerns itself with the part language plays in maintaining the social roles in a community. Sociolinguists attempt to isolate those linguistic features that are used in particular situations and that mark the various social relationships among the participants and the significant elements of the situation. Influences on the choice of sounds, grammatical elements, and vocabulary items may include such factors as age, sex, education, occupation, race, and peer-group identification, among others.
