Against the background of language and nation formation in Indonesia, this book demonstrates how language planning is inseparable from the broader actions of the state, and how postcolonial nationalism and globalization have had profound implications for language use and state actions to control it. Using language planners’ texts, national and regional policy statements and the discussions of university English majors, it explores the borders of what can be defined as Indonesian, Javanese and English languages, and how this is informed by ideologies of language and nationalism in contemporary Indonesia. The tensions played out in the book between the ideologically perceived languages around which policies are built and the realities of linguistic performance and the resources of the individual are echoed across the globe, making this book crucial reading for anyone interested in the interplay of language planning and language use.
