This course introduces you to fundamental concepts and approaches involved in the study of the links between language and society. We will look at a number of important approaches to sociolinguistic research, and cover the topics most central to the discipline and its development. These include language variation and change, which usually refers to social, geographical and stylistic differences within a single language and how they change through time; language contact, including pidginisation and creolisation and societal multilingualism, including language shift, language death and language revival.
