This book offers both an empirical examination of language ideologies and language policies in post-Arab Spring Tunisia and a detailed critical and interdisciplinary model of Language Policy and Planning (LPP). The authors present a comprehensive picture of how multiple language ideologies interact and play out as language policy against a background of political turmoil in a country with a complex history of indigenous and colonial languages. They utilise critical perspectives from Sociolinguistics and Applied Linguistics and add Critical Discourse Studies and a Discourse-Historical Approach to produce a model of LPP for scholars in other settings to describe and work to improve their own specific language contexts.
