Among numerous fieldwork reports on the grammar of Chinese dialects in recent years, few of them combine a description of contemporary grammar with analysis of diachronic development. A recent achievement in this field is A Synchronic and Diachronic Study of the Grammar of the Chinese Xiang Dialects, written by Yunji Wu. This book under review here represents a major contribution to the synchronic grammar of Xiang dialects, and provides a good example of the study of Chinese dialectal grammar based on both modern oral data and historical records.
