This book questions assumptions about the nature of language and how language is conceptualized. Looking at diverse contexts from sign languages in Indonesia to literacy practices in Brazil, from hip-hop in the US to education in Bosnia and Herzegovina, this book forcefully argues that a critique of common linguistic and metalinguistic suppositions is not only a conceptual but also a sociopolitical necessity. Just as many notions of language are highly suspect, so too are many related concepts premised on a notion of discrete languages, such as language rights, mother tongues, multilingualism, or code-switching. Definitions of language in language policies, education and assessment have material and often harmful consequences for people. Unless we actively engage with the history of invention of languages in order to radically change and reconstitute the ways in which languages are taught and conceptualized, language studies will not be able to improve the social welfare of language users.

Alastair Pennycook is concerned with how we understand language in relation to globalization, colonial history, identity, popular culture and pedagogy. Publications have therefore focused on topics such as The cultural politics of English as an international language (Longman, 1994), English and the discourses of colonialism (Routledge, 1998), Critical applied linguistics: A critical introduction (Lawrence Erlbaum, 2001) and Global Englishes and transcultural flows (Routledge, in press). This current book on disinvention is the result of a sustained dialogue with Sinfree Makoni on language, politics and the world. Alastair is Professor of Language in Education at the University of Technology Sydney.
