The object of sociolinguistic research is language in society. Language’s history, language’s current situation and language’s development are all inseparable from groups of people who use language, and all of these have an intimate relationship with humanity and society. Language is the tool of communication for people. Language exists only within society; once one leaves society, there is no language. In both studying and researching language, one cannot leave societal life aside.
The content of sociolinguistics includes hierarchies in language and society, ethnic communities and languages, gender differences in language, linguistic and speech situations, communication and interaction between language and society, language’s ethnic variants, and geographic conditions and language. Sociolinguistics is a branch of linguistics, yet it is also its origin. This course gives an account of sociolinguistic theory and research methods, and through case study analysis, allows students to design their own research proposals, engage in real linguistic studies, and connect theory with reality.
