Trans–New Guinea (TNG) is an extensive family of Papuan languages spoken on the island of New Guinea and neighboring islands ‒ corresponding to the country Papua New Guinea as well as parts of Indonesia.
The Papuan languages are the non-Austronesian and non-Australian languages spoken on the western Pacific island of New Guinea, as well as neighbouring islands in Indonesia, Papua New Guinea, Solomon Islands, and East Timor by around 4 million people. It is a strictly geographical grouping, and does not imply a genetic relationship. The concept of Papuan (non-Austronesian) speaking Melanesians as distinct from Austronesian-speaking Melanesians was first suggested and named by Sidney Herbert Ray in 1892.
The East Papuan languages is a defunct proposal for a family of Papuan languages spoken on the islands to the east of New Guinea, including New Britain, New Ireland, Bougainville, Solomon Islands, and the Santa Cruz Islands. There is no evidence that these languages are related to each other, and the Santa Cruz languages are no longer recognized as Papuan.
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 Mairasi languages, also known as Etna Bay are a small independent family of Papuan languages in the classifications of Malcolm Ross and Timothy Usher, that had been part of Stephen Wurm's Trans–New Guinea proposal. They are named after Etna Bay, located in the southeastern corner of West Papua province, in Indonesia.
The Nimboran languages are a small family of Papuan languages, spoken in the Grime River watershed, that had been part of Stephen Wurm's Trans–New Guinea proposal. However, when proto-Nimboran pronouns are reconstructed (*genam "I" and kom or komot "thou"), they have little resemblance to the proto-TNG pronouns *na and *ga. Usher places them in a North Papuan stock that resembles Cowan's proposal.
The Piawi languages are a small family of Papuan languages spoken in the Schraeder Range of the Madang Highlands of Papua New Guinea that had been part of Stephen Wurm's Trans–New Guinea proposal. They are now connected to the Arafundi and Madang languages.
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 does not now seem tenable, and was abandoned in Ethnologue (2009).
Elseng is a poorly documented Papuan language spoken by about 300 people in the Indonesian province of Papua. It is also known as Morwap, which means "what is it?" ‘Morwap’ is vigorously rejected as a language name by speakers and government officials.
The Greater Awyu or Digul River languages, known in earlier classifications with more limited scope as Awyu–Dumut (Awyu–Ndumut), are a family of perhaps a dozen Trans–New Guinea languages spoken in eastern West Papua in the region of the Digul River. Six of the languages are sufficiently attested for a basic description; it is not clear how many of the additional names may be separate languages.
The Kiwaian languages form a language family of New Guinea. They are a dialect cluster of half a dozen closely related languages. They are grammatically divergent from the Trans–New Guinea languages, and typically have singular, dual, trial, and plural pronouns.
The Kaure–Kosare or Nawa River languages are a small family spoken along the Nawa River in West Papua, near the northern border with Papua New Guinea. The languages are Kaure and Kosare.
The Teberan languages are a well established family of Papuan languages that Stephen Wurm (1975) grouped with the Pawaia language as a branch of the Trans–New Guinea phylum.
The Kamula–Elevala languages are a small family of the Trans–New Guinea languages spoken in the region of the Elevala River.
The Mombum languages, also known as the Komolom or Muli Strait languages, are a pair of Trans–New Guinea languages, Mombum (Komolom) and Koneraw, spoken on Komolom Island just off Yos Sudarso Island, and on the southern coast of Yos Sudarso Island, respectively, on the southern coast of New Guinea. Komolom Island is at the southern end of the Muli Strait.
The Mailuan or Cloudy Bay languages are a small family of Trans–New Guinea languages spoken around Cloudy Bay in the "Bird's Tail" of New Guinea. They are classified within the Southeast Papuan branch of Trans–New Guinea.
The Touo language, also known as Baniata (Mbaniata) or Lokuru, is spoken over the southern part of Rendova Island, located in the Western Province of the Solomon Islands.
The Demta–Sentani languages form a language family of coastal Indonesian Papua near the Papua New Guinea border.
Pawaia, also known as Sira, Tudahwe, Yasa, is a Papuan language that forms a tentative independent branch of the Trans–New Guinea family in the classification of Malcolm Ross (2005).
Proto-Trans–New Guinea is the reconstructed proto-language ancestral to the Trans–New Guinea languages. Reconstructions have been proposed by Malcolm Ross and Andrew Pawley.
