Yahadian is a Papuan language of the Bird's Head Peninsula of Southwest Papua. It is spoken in Yahadian village, Kais District, South Sorong Regency. Overall, Yahadian is poorly documented, with only enough data for a sketch of the language's structure.: 628  It is considered "endangered" by Ethnologue.

Geographic distribution

Yahadian is a member of the Trans–New Guinea languages, spoken on the northwestern corner of the island of New Guinea. Three villages speak Yahadian: Mugim, Yahadian, and (parts of) Kais, with an estimated 1,200 speakers in 2002. They are all located on the south side of the Bird's Head peninsula in Indonesia.: 571 

Yahadian is most closely related to Konda; the two languages appear to form a dialect continuum. Yahadian speakers in the village of Mugim reported that they could "easily" understand Konda speakers. They are also the only two South Bird's Head languages that do not mark gender on nouns.: 604 

It does not appear to have a close relationship with its eastern neighbor, the Inanwatan language, with limited lexical overlap (8%) and far different phonology and morphology.

Notes

  1. ↑ de Vries writes the palato-alveolar plosives in IPA as if they were affricates, but still considers them plosives.
  2. ↑ de Vries marks these phonemes as members of the same category but counts them as separate phonemes to reach the total of 21
