As the first volume of a multi-volume set on Chinese phonetics, this book gives a full picture of the historical development of the Chinese language and studies the phonetics of the early form of Chinese, i.e. Old Chinese. Chinese language history is generally split into three phases: 1) Old Chinese, the form of the Chinese language spoken between the 18th century BC and the 3rd century AD, 2) Middle Chinese, between the 4th century AD to around the 12th century AD, and 3) Modern Chinese, since the 13th century. In this volume, the author first introduces basic issues in Chinese language study, including research objectives, methodology, existing scholarship, periodization, and the distinctive linguistic characteristics of each period. The core chapters then describe and analyze the phonetical systems of Old Chinese, covering the initials system and related eight aspects, two types of rhyme groups, ancient finals, and the tonal system. This comprehensive groundwork on Chinese phonetical history will be a must read for scholars and students studying Chinese language, linguistics and especially for those wishing to become acquainted with Old Chinese phonetics.
