Trans–New Guinea (TNG) is an extensive family of Papuan languages spoken on the island of New Guinea and neighboring islands, a region corresponding to the country Papua New Guinea as well as parts of Indonesia.
The Papuan languages are the non-Austronesian languages spoken on the western Pacific island of New Guinea, as well as neighbouring islands in Indonesia, Solomon Islands, and East Timor. It is a strictly geographical grouping, and does not imply a genetic relationship.
The East Geelvink Bay or East Cenderawasih languages are a language family of a dozen Papuan languages along the eastern coast of Geelvink Bay in Indonesian Papua, which is also known as Sarera Bay or Cenderawasih.
The West Papuan languages are a proposed language family of about two dozen non-Austronesian languages of the Bird's Head Peninsula of far western New Guinea, the island of Halmahera and its vicinity, spoken by about 220,000 people in all. It is not established if they constitute a proper linguistic family or an areal network of genetically unrelated families.
The Lower Mamberamo languages are a recently proposed language family linking two languages spoken along the northern coast of Papua province, Indonesia, near the mouth of the Mamberamo River. They have various been classified either as heavily Papuanized Austronesian languages belonging to the SHWNG branch, or as Papuan languages that had undergone heavy Austronesian influence. Glottolog 3.4 classifies Lower Mamberamo as Austronesian, while Donohue classifies it as Papuan. Kamholz (2014) classifies Warembori and Yoke each as coordinate primary subgroups of the South Halmahera–West New Guinea languages.
The Eastern Trans-Fly languages are a small independent family of Papuan languages spoken in the Oriomo Plateau to the west of the Fly River in New Guinea.
The East Bird's Head–Sentani languages form a family of Papuan languages proposed by Malcolm Ross which combines the East Bird's Head and Sentani families along with the Burmeso language isolate. Sentani had been a branch of Stephen Wurm's proposal for Trans–New Guinea. It has lexical similarities with the Asmat–Kamoro languages, but Ross does not believe these demonstrate a genealogical relationship.
Sulka is a language isolate of New Britain, Papua New Guinea. In 1991, there were 2,500 speakers in eastern Pomio District, East New Britain Province. Villages include Guma in East Pomio Rural LLG. With such a low population of speakers, this language is considered to be endangered. Sulka speakers had originally migrated to East New Britain from New Ireland.
The Kol language is a language spoken in eastern New Britain island, Papua New Guinea. There are about 4000 speakers in Pomio District of East New Britain Province, mostly on the southern side of New Britain island.
The North Bougainville or West Bougainville languages are a small language family spoken on the island of Bougainville in Papua New Guinea. They were classified as East Papuan languages by Stephen Wurm, but this no longer seems tenable, and was abandoned in Ethnologue (2009).
The Central Solomon languages are the four Papuan languages spoken in the state of Solomon Islands.
The South Bougainville or East Bougainville languages are a small language family spoken on the island of Bougainville in Papua New Guinea. They were classified as East Papuan languages by Stephen Wurm, but this does not now seem tenable, and was abandoned in Ethnologue (2009).
The East New Britain languages are a possible small language family spoken on the Gazelle Peninsula of New Britain in Papua New Guinea. They were classified as East Papuan languages by Wurm, but this does not now seem tenable. The only comparative work that has been done between the two branches of the proposed family is Ross (2001), which shows similarities in the pronouns.
Warembori is a moribund language spoken by about 600 people in Warembori village, Mamberamo Hilir District, Mamberamo Raya Regency, located around river mouths on the north coast of Papua, Indonesia.
Kazukuru is an extinct language that was once spoken in New Georgia, Solomon Islands. The Dororo and Guliguli languages were transcriptional variants, dialects, or closely related. The speakers of Kazukuru gradually merged with the Roviana people from the sixteenth century onward and adopted Roviana as their language. Kazukuru was last recorded in the early twentieth century when its speakers were in the last stages of language shift. Today, Kazukuru is the name of a clan in the Roviana people group.
The Reef Islands – Santa Cruz languages are a branch of the Oceanic languages comprising the languages of the Santa Cruz Islands and Reef Islands:
Bilua is the most populous Papuan language spoken in the Solomon Islands. It is a Central Solomon language spoken by about 9,000 people on the island of Vella Lavella. It is one of the four Papuan non-Austronesian languages spoken in the Solomon Islands.
The West Trans–New Guinea languages are a suggested linguistic linkage of Papuan languages, not well established as a group, proposed by Malcolm Ross in his 2005 classification of the Trans–New Guinea languages. Ross suspects they are an old dialect continuum, because they share numerous features that have not been traced to a single ancestor using comparative historical linguistics. The internal divisions of the languages are also unclear. William A. Foley considers the TNG identity of the Irian Highlands languages at least to be established.
West Bird's Head languages are a small family of poorly documented Papuan languages spoken on the Bird's Head Peninsula of New Guinea.
Mpur is a language isolate spoken in and around Mpur and Amberbaken Districts in Tambrauw Regency of the Bird's Head Peninsula, New Guinea. It is not closely related to any other language, and though Ross (2005) tentatively assigned it to the West Papuan languages, based on similarities in pronouns, Palmer (2018), Ethnologue, and Glottolog list it as a language isolate.
