Languages

Wilbrink (2004) lists 4 distinct language varieties.^[1][2]

• Bayono (Enamesi, Swesu), Kovojab (Kvolyab, Kopoyap)
• Awbono, Densar

Classification

Noting insufficient evidence, Pawley and Hammarström (2018) leave Bayono–Awbono as unclassified rather than as part of Trans-New Guinea.^[3] However, according to Dryer (2022), based on a preliminary quantitative analysis of data from the ASJP database, Bayono–Awbono is likely to be a subgroup of Trans–New Guinea.^[4]

Timothy Usher finds enough evidence to classify Awbono–Bayono within the Greater Awyu (Digul River) family.^[5]

Wilbrink (2004) notes limited similarity with the neighboring Ok languages, and does not classify Bayono–Awbono with Ok.^[1]

Pronouns

The pronouns demonstrate resemblances to the neighboring Ok and Greater Awyu languages, and the pronouns are consistent with Bayono-Awbono belonging to the Trans–New Guinea family:
