Middle Sepik languages

The Middle Sepik languages comprise diverse groups of Sepik languages spoken in northern Papua New Guinea. The Middle Sepik grouping is provisionally accepted by Foley (2018) based on shared innovations in pronouns, but is divided by Glottolog. They are spoken in areas surrounding the town of Ambunti in East Sepik Province.

The languages are:
