Yaul language

Yaul, also known as Ulwa, is a severely endangered Keram language of Papua New Guinea. It is spoken fluently by fewer than 700 people and semi-fluently by around 1,250 people in four villages of the Angoram District of the East Sepik Province: Manu, Maruat, Dimiri, and Yaul. Currently, no children are being taught Ulwa, which has led to the rapid decline of intergenerational transmission for this language.

According to Barlow (2018), speakers in Maruat, Dimiri, and Yaul villages speak similar versions of Ulwa, while those in Manu speak a considerably different version. Thus, he postulates that there are two different dialects of Ulwa.
