Bougainville Island is the main island of the Autonomous Region of Bougainville, which is part of Papua New Guinea. It was previously the main landmass in the German Empire-associated North Solomons. Its land area is 9,300 km2 (3,600 sq mi). The population of the whole province, including nearby islets such as the Carterets, is approximately 300,000. The highest point is Mount Balbi, on the main island, at 2,715 m (8,907 ft). The much smaller Buka Island, c. 500 km2 (190 sq mi), lies to the north, across the 400–500 m (1,300–1,600 ft) wide Buka Strait. Even though the strait is narrow, there is no bridge across it, but there is a regular ferry service between the key settlements on either side. The main airport in the north is in the town of Buka.
The New Georgia Islands are part of the Western Province of Solomon Islands. They are located to the northwest of Guadalcanal. The larger islands are mountainous and covered in rain forest. The main islands are New Georgia, Vella Lavella, Kolombangara, Ghizo, Vangunu, Rendova and Tetepare. They are surrounded by coral reefs and include the Marovo Lagoon.
New Georgia, with an area of 2,037 km2 (786 sq mi), is the largest of the islands in Western Province, Solomon Islands, and the 200th-largest island in the world.
The approximately 450 Oceanic languages are a branch of the Austronesian languages. The area occupied by speakers of these languages includes Polynesia, as well as much of Melanesia and Micronesia. Though covering a vast area, Oceanic languages are spoken by only two million people. The largest individual Oceanic languages are Eastern Fijian with over 600,000 speakers, and Samoan with an estimated 400,000 speakers. The Gilbertese (Kiribati), Tongan, Tahitian, Māori and Tolai languages each have over 100,000 speakers. The common ancestor which is reconstructed for this group of languages is called Proto-Oceanic.
The family of Southeast Solomonic languages forms a branch of the Oceanic languages. It consists of some 26 languages covering the South East Solomon Islands, from the tip of Santa Isabel to Makira. The fact that there is little diversity amongst these languages, compared to groups of similar size in Melanesia, suggests that they dispersed in the relatively recent past. Bugotu and Gela are two of the most conservative languages.
The Meso-Melanesian languages are a linkage of Oceanic languages spoken in the large Melanesian islands of New Ireland and the Solomon Islands east of New Guinea. Bali is one of the most conservative languages.
The Huon Gulf languages are Western Oceanic languages spoken primarily in Morobe Province of Papua New Guinea. They may form a group of the North New Guinea languages, perhaps within the Ngero–Vitiaz branch of that family.
The Solomon Sea is a sea located within the Pacific Ocean. It lies between Papua New Guinea and Solomon Islands. Many major battles were fought there during World War II.
The Southern Oceanic languages are a linkage of Oceanic languages spoken in Vanuatu and New Caledonia. It was proposed by John Lynch in 1995 and supported by later studies. It appears to be a linkage rather than a language family with a clearly defined internal nested structure.
Santa Isabel Island is the longest in Solomon Islands, the third largest in terms of surface area, and the largest in the group of islands in Isabel Province.
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).
Duke is an Oceanic language now spoken by about 3,000 people on Kolombangara island, Solomon Islands. Duke is an exonymic name. Endonymic names are Dughore (Ndughore) and Kolei. Dughore is also a name for an area in southwest Kolombangara, Kolei is the general bilateral address term specific to Nduke. A more recent alternative name is 'Kolombangara'.
Between 60 and 70 languages are spoken in the Solomon Islands Archipelago which covers a broader area than the nation state of Solomon Islands, and includes the island of Bougainville, which is an autonomous province of Papua New Guinea (PNG). The lingua franca of the archipelago is Pidgin, and the official language in both countries is English.
Teop is a language of northern Bougainville, Papua New Guinea. It falls within the Oceanic languages, a subgrouping of the Austronesian language family. According to Malcolm Ross, Teop belongs to the Nehan-Bougainville family of languages, part of the Northwest Solomonic group of the Meso-Melanesian cluster within the Oceanic languages. Its closest relative is Saposa.
Bannoni, also known as Tsunari, is an Austronesian language of Papua New Guinea. It has approximately 1,000 native speakers. The Banoni people refer to their language as Tsunari, but acknowledge the name Banoni and accept it as well. Tsunari technically translates to 'their truth'.
