Any research question or application relating to language variation and/or use can be approached from a corpus linguistic perspective. The goals of The Cambridge Handbook of English Corpus Linguistics (CHECL) are to survey the breadth of these research questions and applications in relation to the linguistic study of English. The handbook addresses a range of topics, including chapters on lexical variation, grammatical variation, historical change, online language and social media, multimodal corpora, the linguistic description of dialects and registers, and applications to language teaching and translation. In each chapter, authors assess what we have learned from corpus-based investigations to date and provide detailed case studies that illustrate how corpus analyses can be employed for empirical descriptions, documenting surprising patterns of language use that are often unanticipated previously. By bringing together diverse perspectives and cutting-edge research, this volume serves as a comprehensive resource for researchers seeking to understand and apply a corpus-based approach to the study of English.
