This book is the first descriptive grammar of Tuatschin, a Sursilvan Romansh dialect spoken by approximately 800 people in the westernmost part of the Romansh territory, in the canton of Grisons in southeastern Switzerland. The description is mainly based on narratives and elicitation, collected during fieldwork conducted between 2016 and 2020. Besides the grammatical description, it also offers a variety of narratives produced by female and male native speakers between thirty and eighty years of age.

Japhug is a vulnerable Gyalrongic language, which belongs to the Trans-Himalayan (Sino-Tibetan) family. It is spoken by several thousand speakers in Mbarkham county, Rngaba district, Sichuan province, China. This grammar is the result of nearly 20 years of fieldwork on one variety of Japhug, based on a corpus of narratives and conversations, a large part of which is available from the Pangloss Collection. It covers the whole grammar of the language, and the text examples provide a unique insight into Gyalrong culture. It was written with a general linguistics audience in mind, and should prove useful not only to specialists of Trans-Himalayan historical linguistics and typologists, but also to anthropologists doing research in Gyalrong areas. It is also hoped that some readers will use it to learn Japhug and pursue research on this fascinating language in the future.
