In this ambitious book, Jieun Kiaer explores the lives of English words in the twenty-first century, when the creation and use of language has become an increasingly dynamic, interactive, and diverse process in which ordinary people have taken leading roles - offering such coinages as "flexitarian," "MeToo," "glow up," and "shitizen" to "No sabo kids" and beyond. As English language grows ever more diverse, Kiaer believes, we need a paradigm shift. We must acknowledge that all varieties of English are languages in their own right when they are used by a community of speakers. English is a language that belongs to everyone.
