The present work, a grammar of Dhimal, fills an important void in the documentation of the vast and ramified Tibeto-Burman language family. Dhimal, a little known and endangered tongue spoken in the lowlands of southeastern Nepal by about 20,000 individuals, is detailed in this work. With data gathered in the village of Athiyabari, the author crafts a readable description of the western dialect, using over 1000 examples to illustrate usage. Included in this reference work are seventeen texts, riddles, songs and a Dhimal-English glossary. Joining other recent ground-breaking linguistic descriptions by researchers from the Himalayan Languages Project at Leiden University, this grammar of Dhimal will have lasting scientific value and aid the Dhimal community in preserving their language.
