Book excerpt: The Handbook of the Austroasiatic Languages is the first comprehensive reference work on this important language family of South and Southeast Asia. Austroasiatic languages are spoken by more than 100 million people, from central India to Vietnam, from Malaysia to Southern China, including national language Cambodian and Vietnamese, and more than 130 minority communities, large and small. The handbook comprises two parts, Overviews and Grammar Sketches: Part 1) The overview chapters cover typology, classification, historical reconstruction, plus a special overview of the Munda languages. Part 2) Some 27 scholars present grammar sketches of 21 languages, representing 12 of the 13 branches. The sketches are carefully prepared according to the editors’ unifying typological approach, ensuring analytical and notational comparability throughout.
