Book excerpt: Ruanni Tupas presents rich insights into the inequalities of Englishes and the ways in which these inequalities shape and impact English and multilingual speakers from around the world. This edited volume gives a critical take on world Englishes, while showcasing for readers the various inequalities in treatment towards the people who speak English differently, as well as the injustice in that treatment. Research methodologies are explored, providing a glimpse into how data are collected and lending a more thorough look into each study and its conclusions. Chapters address the geopolitics of knowledge production in the teaching, learning and use of English, with strong representations from the peripheries of sociolinguistic studies of English. English is constructed as a language which enables socioeconomic mobility which is one factor that increases the importance of research into this issue, and this book enables researchers to widen their methods of research and apply them to their area of study. A valuable text for academic researchers, as well as postgraduate and advanced undergraduate students, to better understand the linguistic, sociopolitical and epistemic inequality in English communication. It also provides readers with alternative perspectives on lingua-cultural pluralism to unpack social inequalities and hierarchies that exist today.
