This book explores the dynamic landscape of language in Macau, focusing on how multilingualism shapes and is shaped by the city's educational, social, and economic transformations. Drawing on research, case studies, and lived experiences, the authors examine the interplay between language policy, classroom practice, and community life in one of Asia's most linguistically diverse urban centers. The volume offers insights into the challenges and opportunities of multilingual education, the impact of recent global events, and the evolving roles of Cantonese, Mandarin, Portuguese, and English in Macau's development. Bridging theory and practice, the book provides educators, policymakers, and researchers with a nuanced understanding of applied linguistics in action within a rapidly changing society.
