Sociolinguistics is the study of the connection between language and society and the way people use language in different social situations. It also studies how language varieties differ between groups separated by certain social variables (e.g., ethnicity, religion, status, gender, level of education, age, etc.) and how creation and adherence to these rules is used to categorize individuals in social or socioeconomic classes. As the usage of a language varies from place to place, language usage also varies among social classes, and it is these sociolects that sociolinguistics studies.
The basic notion underlying sociolinguistics is quite simple: Language use symbolically represents fundamental dimensions of social behavior and human interaction. The notion is simple, but the ways in which language reflects behavior can often be complex and subtle. Furthermore, the relationship between language and society affects a wide range of encounters--from broadly based international relations to narrowly defined interpersonal relationships.
For example, sociolinguists might investigate language attitudes among large populations on a national level, such as those exhibited in the US with respect to the English-only amendment--the legislative proposal to make English the 'official' language of the US. Similarly, we might study the status of French and English in Canada or the status of national and vernacular languages in the developing nations of the world as symbols of fundamental social relations among cultures and nationalities. In considering language as a social institution, sociolinguists often use sociological techniques involving data from questionnaires and summary statistical data, along with information from direct observation.
A slightly different concern with language and society focuses more closely on the effect of particular kinds of social situations on language structure. For example, language contact studies focus on the origin and the linguistic composition of pidgin and creole languages. These special language varieties arise when speakers from mutually unintelligible language groups need a common language for communication. Throughout the world, there are many sociohistorical situations that have resulted in these specialized language situations--in the Caribbean, Africa, South America, Asia, and the Pacific Islands. In examining language contact situations, it is also possible to examine not only the details of a particular language but also the social and linguistic details that show how bilingual speakers use each language and switch between them.
Another approach to language and society focuses on the situations and uses of language as an activity in its own right. The study of language in its social context tells us quite a bit about how we organize our social relationships within a particular community. Addressing a person as 'Mrs.', 'Ms.', or by a first name is not really about simple vocabulary choice but about the relationship and social position of the speaker and addressee. Similarly, the use of sentence alternatives such as Pass the salt, Would you mind passing the salt, or I think this food could use a little salt is not a matter of simple sentence structure; the choice involves cultural values and norms of politeness, deference, and status.
In approaching language as a social activity, it is possible to focus on discovering the specific patterns or social rules for conducting conversation and discourse. We may, for example, describe the rules for opening and closing a conversation, how to take conversational turns, or how to tell a story or joke.
