Language policy, planning and management are critical components of national governance. These policies ensure equitable access to education, public services and cultural expression in various languages, enhancing social unity. Governments strategically plan language usage to empower marginalized communities, preserving their cultural identities and facilitating intergroup communication. Effective management frameworks streamline policy implementation, optimizing resources and safeguarding linguistic rights. Moreover, these initiatives stimulate economic growth by facilitating multilingual communication in global markets, positioning language diversity as a strategic asset rather than a barrier. Thus, language policy not only strengthens national identity but also promotes social harmony and economic prosperity through the respectful management of linguistic resources. The book aims to shed light on some of the unexplored aspects of language policy, planning and management. While understanding the long-term perspectives of the topics, the book makes an effort in highlighting their impact as a modern tool for the growth of the discipline. It aims to serve as a resource guide for students and experts alike and contribute to the growth of the discipline.
