With close to 100 million speakers, Tai-Kadai constitutes one of the world’s major language families. The Tai-Kadai Languages provides a unique, comprehensive, single-volume tome covering much needed grammatical descriptions in the area. It presents an important overview of Thai that includes extensive cross-referencing to other sections of the volume and sign-posting to sources in the bibliography. The volume also includes much new material on Lao and other Tai-Kadai languages, several of which are described here for the first time. Much-needed and highly useful, The Tai-Kadai Languages is a key work for professionals and students in linguistics, as well as anthropologists and area studies specialists. ANTHONY V. N.
