Heller and Mc Elhinny reinterpret sociolinguistics for the twenty-first century with an original approach to the study of language that is situated in the political and economic contexts of colonialism and capitalism. In the process, they map out a critical history of how language serves, and has served, as a terrain for producing and reproducing social inequalities. The authors ask how, and by whom, ideas about language get unevenly shaped, offering new perspectives that will excite readers and incite further research for years to come.
