"Grammar and Linguistics: Core Concepts" offers a comprehensive introduction to the field of linguistics, focusing on the practical and analytical skills needed to understand complex linguistic patterns. We start with a small set of robust analytical tools, applying them to basic phenomena before advancing to more intricate structures. Our book covers key topics such as lexical valence and the rules governing the sharing of component values. Each chapter includes integrated activities and issues, equipping students with the tools to recognize and assess linguistic patterns. We also address syntactic complexity in academic English, using corpus-based studies to challenge prevailing stereotypes in linguistics. Our authors demonstrate that syntactic change occurs in both written and spoken language, emphasizing the compressed nature of academic writing and its role in significant linguistic changes over the past century. Supported by extensive textual evidence, this book is essential reading for discourse analysts, sociolinguists, applied linguists, descriptive linguists, and historical linguists.
