Now in its second edition, this handbook is a comprehensive and up-to-date resource that explores the applications of corpus-based research in linguistics. Since the first edition, corpus linguistics has evolved dramatically, and this edition has been fully updated to reflect these developments, with new chapters on emerging areas such as online language, legal discourse, and lexical complexity in learner language. Bringing together contributions from leading scholars, it critically evaluates methodologies, presents cutting-edge research, and includes empirical case studies that showcase corpus analysis in action. Each chapter surveys key studies, assesses methodological strengths and weaknesses, and highlights what corpus linguistics has uncovered about language variation and use. Covering topics ranging from phraseology to World Englishes, it serves as an essential reference for linguistics students, researchers, and educators. Whether you're new to corpus linguistics or an experienced scholar, this handbook provides valuable insights into the evolving role of corpora in linguistic research.
