Yali is a Trans-New Guinea language, spoken in the highlands of Papua, Indonesia. It belongs to the Dani subgroup of the West Trans New-Guinea linkage, and is spoken by approximately 30,000 people in the mountainous area east of the city of Wamena. This book consists of two parts. The central part is a Yali-English-German dictionary, one among few detailed and philologically sound dictionaries of a TNG highland language. It contains more than 3000 headwords, which cover a large amount of the Yali everyday lexicon, as well as a variety of culturally relevant concepts used in Yali rituals and traditional myths. Most entries include detailed definitions and example sentences that illustrate the use of the respective headword. The data for this dictionary were collected by the German missionary Siegfried Zöllner and his wife Ilse between 1961 and 1973.
