Chinese language acquisition has been discussed from pedagogical and discoursal perspectives, however this innovative book presents a linguistic perspective on Chinese as a second language. Bridging theory and practice, it provides an authoritative, research-based foundation to enhance Chinese language teaching and learning methodologies globally. Bringing together 18 leading scholars to explore the linguistic underpinnings of Chinese language teaching and acquisition, the chapters cover key areas of language acquisition such as tone, prosody, Chinese characters, syntax, aspect, and pragmatic competence, and offer new theoretical perspectives, such as cognitive approaches, alongside practical applications. Combining the best scholarship from both Chinese and non-Chinese perspectives, it presents a unique, cross-cultural approach, reflecting global collaboration in the Chinese as a Second Language Research Association (CASLAR) community. Aiming to strengthen the theoretical foundations of language teaching, and advancing Chinese language teaching methodologies, this book is an essential resource for educators and students, as well as researchers.
