Retired in ISO 639-3: Merge into Korowai [khe]
Excerpt from change request document:
There is currently an SIL linguist working in the area who is finding out that North Korowai is intelligible with Korowai. Quoting him from an email: "We haven't done any dialect intelligibility testing yet, but lexical similarity is 90% and they seem to understand each other without trouble. During the Baseline Study we had a South Korowai speaker do the interpretation and when we asked North Korowai speakers if they had any questions about the purpose of our Baseline Study they replied that they had just heard the explanation in their own language, so they had no questions. And from their actions is was clear that they understood. I myself can understand North Korowai speakers, if they do not speak too fast. Their pronunciation is a bit different and I plan to look into that in the future. North and South have some differing vocabulary but seem to have no problem understanding each other. Grammar doesn't seem to be different."
