The Koam languages are spoken next to the Yuat languages, but two groups are unrelated.[1]
Names
The name Koam is used by Foley (2018), while the name Ulmapo (coined from the first two letters of each of the three daughter languages) is used by Barlow (2018) and Glottolog 4.0.[3]
Donald Laycock (1973) noted that the Mongol–Langam languages mark nouns for pluralisation, like the Lower Sepik languages (Nor–Pondo languages) and Yuat languages, and also that the lexicon also shows many resemblances to Yuat languages, while pronouns are similar to the Grass (Keram) languages (Ramu).[7]Malcolm Ross (2005) accepts them as Ramu languages based on their pronouns.[8] With additional data from recent research, Usher confirms their position in the Keram branch of the Ramu family.[9]
