Bad English investigates the impact of increasing language diversity, precipitated by migration, globalisation, and new forms of communication, in transforming contemporary literature in Britain. Considering writers whose work engages experimentally, playfully, and ambivalently with English's power, while exploring what it means to move between forms of language, it makes the case for literature as the pre-eminent medium to probe the terms of linguistic belonging, and for a diverse and growing field of writing in Britain defined by its inside/outside relationship to English in its institutionalised forms. Bad English offers innovative readings of writers including James Kelman, Tom Leonard, Suhayl Saadi, Raman Mundair, Daljit Nagra, Xiaolu Guo, Leila Aboulela, Brian Chikwava, and Caroline Bergvall. Drawing on insights from applied linguistics and translation studies as well as literary scholarship, it will appeal to students and academics across these disciplines.
