Yapunda language

Yapunda, or Yeri, is a Torricelli language of Papua New Guinea.

Yeri is a language estimated to be spoken by 100-150 people. The speakers with the most proficiency are generally 40 years of age or older. The speakers who make up the younger demographics tend to either speak a more simplified version of the language or favor the use of Tok Pisin, an English creole, which is the universal language used with neighboring villages.

The village of Yeri is made up of a variety of hamlets along the Om river. Located in the Torricelli mountains, the village was originally deeper in the forest. Most village members decided to relocate nearer to the river, while a few stayed behind and continued habitation in the forest.

The Yeri village is structured as a patrilineal clan system. As of 2012, there were seven clans within the village. There is a history of bride exchange between villages and clans, with patrilocal residence following marriage.
