This book examines medium-sized linguistic communities in urban contexts against the backdrop of the language policies which have been implemented in these respective areas. The authors provide new data and reflections on these linguistic communities which have languages somewhere in between the majority and minority, and re-evaluate the opposition between 'majority' and 'minority'. The book focuses on seven European cities, providing detailed information on their current situation and on the corresponding evolution of their linguistic repertoire. The book aims to improve our understanding of how and why languages live and decay, and of how intercultural cities, where communities show interest in each other's culture and language, can be better developed and encouraged.
