What is ethnicity? Is there a “white” way of speaking? Why do people sometimes borrow features of another ethnic group’s language? Why do we sometimes hear an accent that isn’t there? This lively overview reveals the fascinating relationship between language and ethnic identity, exploring the crucial role it plays in both revealing a speaker’s ethnicity and helping to construct it. Drawing on research from a range of ethnic groups around the world, it shows how language contributes to the social and psychological processes involved in the formation of ethnic identity, exploring both the linguistic features of ethnic language varieties and also the ways in which language is used by different ethnic groups. The first overview of this important topic, Language and Ethnicity will be welcomed by students and researchers in sociolinguistics, as well as anybody interested in ethnic issues, language and education, interethnic communication, and the relationship between language and identity.
