Introduction to English Across Contexts offers a structured, integrated approach to understanding the English language, combining insights from applied linguistics, pragmatics, sociolinguistics, discourse studies, and cultural research.Organised into three thematic parts, it explores language as a code (focusing on its structural regularities and patterns of use), as interaction (examining the role of context, intention, and social dynamics in meaning exchange), and as representation (exploring the ways in which language constructs and conveys knowledge and reality). This book bridges the gaps between these dimensions, enabling readers to grasp how grammar, interactional goals, and meaning-making intersect in real-world communication. By combining established models with an emphasis on usability, this volume equips readers with analytical tools to understand, evaluate, and produce texts with greater clarity, appropriateness, and awareness.Designed for undergraduate and postgraduate courses, this book provides students, researchers, and educators with precise terminology, practical models, and analytical tools. It is an essential resource for understanding English in academic, professional, and cultural settings.
