This book introduces applied linguistics as a field concerned with the practical use of language knowledge across diverse social, educational, and technological contexts. It presents an integrated perspective on how linguistic theories are utilised to analyse real-world language issues, ranging from communication and learning to language processing and interpretation. The discussion considers cognitive and structural dimensions of language, alongside the influence of cultural and social factors that shape language use in different communities. It also reflects on the growing role of technology in language analysis and application, highlighting developments that support language recognition, assessment, and processing in modern environments. Attention is given to the evaluation of language proficiency and the systematic study of linguistic patterns, demonstrating how applied linguistics connects theory with practice. By linking conceptual insight with contemporary applications, the text offers a comprehensive understanding of the field.

The book aims to equip readers with the ability to apply linguistic knowledge effectively, enabling them to analyse language-related problems, support communication practices, and engage with evolving developments in language study and application.
