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 Torricelli languages are a family of about fifty languages of the northern Papua New Guinea coast, spoken by about 80,000 people. They are named after the Torricelli Mountains. The most populous and best known Torricelli language is Arapesh, with about 30,000 speakers.
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 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 Bird's Head Peninsula or Doberai Peninsula, is a large peninsula that makes up the northwest portion of the island of New Guinea, comprising the Indonesian provinces of Southwest Papua and West Papua. It is often referred to as The Vogelkop, and is so named because its shape looks like a bird's head on the island of New Guinea. The peninsula at the opposite end of the island is called the Bird's Tail Peninsula. The peninsula just to the south is called the Bomberai Peninsula.
Bomberai Peninsula is located in the Western New Guinea region. It is south of the Bird's Head Peninsula, and Bintuni Bay separates the two peninsulas. To the west lies the Sebakor Bay and to the south Kamrau Bay. On the southeast Arguni Bay lies between the peninsula and the Bird's Neck Isthmus.
The South Bird's Head or South Doberai languages are three families of Papuan languages. They form part of the Trans–New Guinea languages in the classifications of Malcolm Ross (2005) and Timothy Usher (2020), though Pawley and Hammarström (2018) do not consider them to be part of Trans–New Guinea. However, according to Dryer (2022), based on a preliminary quantitative analysis of data from the ASJP database, South Bird's Head languages are likely to be a subgroup of Trans–New Guinea.
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 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.
Bintuni Bay is the eastward extension or inner bay of Berau Gulf in western New Guinea. It separates the Bird's Head Peninsula on the north from the Bomberai Peninsula on the south. Administratively it is part of West Papua, Indonesia. The bay is 12 miles (19.3 km) wide at its entrance and there are extensive marshes along the shore.
Teluk Bintuni Regency or Bintuni Bay Regency is a regency of West Papua Province of Indonesia. It covers an area of 18,637 km2, comprising administrative districts on three sides of Bintuni Bay, a gulf that separates the Bird's Head Peninsula and Bomberai Peninsula which together form the main geographical constituents of the province; it had a population of 52,422 at the 2010 Census and 87,083 at the 2020 Census; the official estimate as at mid 2023 was 90,101. The administrative centre is the town of Bintuni.
The North Halmahera (NH) languages are a family of languages spoken in the northern and eastern parts of the island of Halmahera and some neighboring islands in Indonesia. The southwestern part of the island is occupied by the unrelated South Halmahera languages, which are a subgroup of Austronesian. They may be most closely related to the languages of the Bird's Head region of West Papua, but this is not well-established.
Mor is a nearly extinct Trans–New Guinea language of Indonesia. It is spoken along the Budidi River and the Bomberai River on the Bomberai Peninsula.
Sumuri or Sumeri is a language spoken in Sumuri District, Teluk Bintuni Regency on the Bomberai Peninsula by about a thousand people.
The Oirata–Makasae, or Eastern Timor, languages are a small family of Papuan languages spoken in eastern Timor and the neighboring island of Kisar.
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.
The Berau Gulf, formerly the MacCleur Gulf, separates the Vogelkop (Doberai) and Bomberai Peninsulas of Western New Guinea. It opens on the Ceram Sea to the west and ends in Bintuni Bay to the east.
