Chinese is the most commonly spoken language in the world and one of the very few contemporary languages whose history is documented in an unbroken tradition extending back to the second millennium. Compared with Western languages, Chinese has a typology with distinguished features in sound system, syntax, and discourse that have a strong impact on Chinese linguistics studies and language learning. Drawing on theoretical models from formal and functional linguistics, discourse analysis, computer-assisted corpus studies, language socialization, and second language acquisition, this volume presents new advances and addresses a broad range of current issues in the study of Chinese linguistics with research studies that originated from the proceedings of the 21st North American Conference on Chinese Linguistics (NACCL-21). As globalization presses on, more and more people are interested in Chinese - its history, structure, research, and new developments. This volume aims to be instrumental. Written in a coherent and structured style, each section is concentrated on a particular linguistic area, and each chapter is self-contained with a clear focus and theoretical framework. It will be valuable to linguists, educators, administrators, specialists, teachers and students of Chinese as a native, second, heritage, or foreign language.
