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.
Indo-Pacific is a hypothetical language macrofamily proposed in 1971 by Joseph Greenberg and now believed to be spurious. It grouped together the Papuan languages of New Guinea and Melanesia with the languages of the Andaman Islands and, tentatively, the languages of Tasmania, both of which are remote from New Guinea. The valid cognates Greenberg found turned out to be reflexes of the less extensive Trans–New Guinea family. Recently the Kusunda language, which is generally seen as a language isolate, is also included in the Indo-Pacific proposal. Greenberg did not include "Australian" in his original 1971 proposal.
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 Foja Range languages, or Tor–Kwerba in more limited scope, are a family of about two dozen Papuan languages. They are named after the Foja Mountains of western New Guinea.
The Bunak language is the language of the Bunak people of the mountainous region of central Timor, split between the political boundary between West Timor, Indonesia, particularly in Lamaknen District and East Timor. It is one of the few on Timor which is not an Austronesian language, but rather a Papuan language of the Timor–Alor–Pantar language family. The language is surrounded by Malayo-Polynesian languages, like Uab Meto and Tetum.
Western Pantar, sometimes referred to by the name of one of its dialects, Lamma, is a Papuan language spoken in the western part of Pantar island in the Alor archipelago of Indonesia. Western Pantar is spoken widely in the region by about 10,000 speakers. Although speakers often use Malay in political, religious, and educational contexts, Western Pantar remains the first language of children of the region, and is acquired to some extent by immigrants.
The Dani or Baliem Valley languages are a family of clearly related Trans–New Guinea languages spoken by the Dani and related peoples in the Baliem Valley in the Highland Papua, Indonesia. Foley (2003) considers their Trans–New Guinea language group status to be established. They may be most closely related to the languages of Paniai Lakes, but this is not yet clear. Capell (1962) posited that their closest relatives were the Kwerba languages, which Ross (2005) rejects.
The Paniai Lakes languages, also known as the Wissel Lakes or Wissel Lakes – Kemandoga River, are a small family of closely related Trans–New Guinea languages spoken in the Paniai Lakes region of the highlands of Western New Guinea in the Paniai Lakes region of Papua. Foley (2003) considers their Trans–New Guinea status to be established.
The (Greater) West Bomberai languages are a family of Papuan languages spoken on the Bomberai Peninsula of western New Guinea and in East Timor and neighboring islands of Indonesia.
The Alor–Pantar languages are a family of clearly related Papuan languages spoken on islands of the Alor archipelago near Timor in southern Indonesia. They may be most closely related to the Papuan languages of eastern Timor, but this is not yet clear. A more distant relationship with the Trans–New Guinea languages of the Bomberai peninsula of Western New Guinea has been proposed based on pronominal evidence, but though often cited has never been firmly established.
The Timor–Alor–Pantar (TAP) languages are a family of languages spoken in Timor, Kisar, and the Alor archipelago in Southern Indonesia. It is the westernmost Papuan language family that survives, and one of two such outlier families in east Nusantara.
The Kainantu–Goroka languages are a family of Papuan languages established by Arthur Capell in 1948 under the name East Highlands. They formed the core of Stephen Wurm's 1960 East New Guinea Highlands family, and are one of the larger branches of Trans–New Guinea in the 2005 classification of Malcolm Ross.
The Dani–Kwerba languages were a hypothetical language family proposed by Arthur Capell in 1962 and adopted by Stephen Wurm as part of his Trans–New Guinea (TNG) phylum. Malcolm Ross reassigned the Dani languages to a West Trans–New Guinea linkage and the Kwerba languages to his Tor–Kwerba family, outside of TNG altogether.
The Orya–Tor languages are a family of just over a dozen Papuan languages spoken in Western New Guinea, Indonesia.
The Oirata–Makasae, or Eastern Timor, languages are a small family of Papuan languages spoken in eastern Timor and the neighboring island of Kisar.
The Kwerbic, or Greater Kwerba, languages are a family of just under a dozen Papuan languages spoken in Indonesia.
The West Papuan Highland languages, also known as the Irian Highland languages, are a branch of the Trans–New Guinea language family proposed by Larson & Larson (1972) and confirmed by Timothy Usher. William A. Foley considers their Trans–New Guinea identity to be established.
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.
