N. J. Enfield 
Languages of Mainland Southeast Asia [PDF ebook] 

Mainland Southeast Asia is one of the most fascinating and complex cultural and linguistic areas in the world. This book provides a rich and comprehensive survey of the history and core systems and subsystems of the languages of this fascinating region. Drawing on his depth of expertise in mainland Southeast Asia, Enfield includes more than a thousand data examples from over a hundred languages from Cambodia, China, Laos, Malaysia, Myanmar, Thailand, and Vietnam, bringing together a wealth of data and analysis that has not previously been available in one place. Chapters cover the many ways in which these languages both resemble each other, and differ from each other, and the diversity of the area’s languages is highlighted, with a special emphasis on minority languages, which outnumber the national languages by nearly a hundred to one. The result is an authoritative treatment of a fascinating and important linguistic area.
