This volume offers a wealth of new information about the forms of several speech acts and their social distribution in Vietnamese as L1 and L2, complemented by a chapter on address forms and listener responses. As the first of its kind, the book makes a valuable contribution to the research literature on pragmatics, sociolinguistics, and language and social interaction in an under-researched and less commonly taught Asian language. PRAGMATICS & INTERACTION, a refereed series sponsored by the University of Hawai'i National Foreign Language Resource Center, publishes research on topics in pragmatics and discourse as social interaction from a wide variety of theoretical and methodological perspectives. P&I particularly welcomes studies on languages spoken in the Asia-Pacific region. Following an About the Authors, Acknowledgments, Transcription Conventions, and an Introduction: Pragmatics Research and Vietnamese (Carsten Roever & Ha?nh th? Nguy?n) the following contents are included: (1) Requesting in Vietnamese as a Second Language (Minh th? Th?y Nguy?n & Helen Basturkmen); (2) Apologizing in Vietnamese as a Native and a Target Language (Lê Gia Anh H?); (3) Complaints in Vietnamese by Native and Nonnative Speakers (Hà Th? Thanh Ð?)
