The Austronesian languages are a language family widely spoken throughout Maritime Southeast Asia, parts of Mainland Southeast Asia, Madagascar, the islands of the Pacific Ocean and Taiwan. They are spoken by about 328 million people. This makes it the fifth-largest language family by number of speakers. Major Austronesian languages include Malay, Javanese, Sundanese, Tagalog, Malagasy and Cebuano. According to some estimates, the family contains 1,257 languages, which is the second most of any language family.
The Western Malayo-Polynesian (WMP) languages, also known as the Hesperonesian languages, are a paraphyletic grouping of Austronesian languages that includes those Malayo-Polynesian languages that do not belong to the Central–Eastern Malayo-Polynesian (CEMP) branch. This includes all Austronesian languages spoken in Madagascar, Mainland Southeast Asia, the Philippines, the Greater Sunda Islands, Bali, Lombok, the western half of Sumbawa, Palau and the Mariana Islands.
The Philippine languages or Philippinic are a proposed group by R. David Paul Zorc (1986) and Robert Blust that include all the languages of the Philippines and northern Sulawesi, Indonesia—except Sama–Bajaw and the Molbog language—and form a subfamily of Austronesian languages. Although the Philippines is near the center of Austronesian expansion from Taiwan, there is little linguistic diversity among the approximately 150 Philippine languages, suggesting that earlier diversity has been erased by the spread of the ancestor of the modern Philippine languages.
The Central–Eastern Malayo-Polynesian (CEMP) languages form a proposed branch of the Malayo-Polynesian languages consisting of over 700 languages.
The Sasak language is spoken by the Sasak ethnic group, which make up the majority of the population of Lombok, an island in the West Nusa Tenggara province of Indonesia. It is closely related to the Balinese and Sumbawa languages spoken on adjacent islands, and is part of the Austronesian language family. Sasak has no official status; the national language, Indonesian, is the official and literary language in areas where Sasak is spoken.
The Central Malayo-Polynesian languages (CMP) are a proposed branch in the Malayo-Polynesian subgroup of the Austronesian language family. The languages are spoken in the Lesser Sunda and Maluku Islands of the Banda Sea, in an area corresponding closely to the Indonesian provinces of East Nusa Tenggara and Maluku and the nation of East Timor, but with the Bima language extending to the eastern half of Sumbawa Island in the province of West Nusa Tenggara and the Sula languages of the Sula archipelago in the southwest corner of the province of North Maluku. The principal islands in this region are Sumbawa, Sumba, Flores, Timor, Buru, and Seram. The numerically most important languages are Bima, Manggarai of western Flores, Uab Meto of West Timor, and Tetum, the national language of East Timor.
The Malayic languages are a branch of the Malayo-Polynesian subgroup of the Austronesian language family. The most prominent member is Malay, a pluricentric language given national status in Brunei and Singapore while also the basis for national standards Malaysian in Malaysia and Indonesian in Indonesia. The Malayic branch also includes local languages spoken by ethnic Malays, further several languages spoken by various other ethnic groups of Sumatra, Indonesia and Borneo even as far as Urak Lawoi in the southwestern coast of Thailand.
Indonesia is home to over 700 living languages spoken across its extensive archipelago. This significant linguistic variety constitutes approximately 10% of the world’s total languages, positioning Indonesia as the second most linguistically diverse nation globally, following Papua New Guinea. The majority of these languages belong to the Austronesian language family, prevalent in the western and central regions of Indonesia, including languages such as Acehnese, Sundanese, and Buginese. In contrast, the eastern regions, particularly Papua and the Maluku Islands, are home to over 270 Papuan languages, which are distinct from the Austronesian family and represent a unique linguistic heritage. The language most widely spoken as a native language is Javanese, primarily by the Javanese people in the central and eastern parts of Java Island, as well as across many other islands due to migration.
Lampung or Lampungic is an Austronesian language or dialect cluster with around 1.5 million native speakers, who primarily belong to the Lampung ethnic group of southern Sumatra, Indonesia. It is divided into two or three varieties: Lampung Api, Lampung Nyo, and Komering. The latter is sometimes included in Lampung Api, sometimes treated as an entirely separate language. Komering people see themselves as ethnically separate from, but related to, Lampung people.
The East Barito languages are a group of a dozen Dayak (Austronesian) languages of Borneo, Indonesia, and most notably Malagasy, the national language of Madagascar. They are named after the Barito River located in South Kalimantan, Indonesia.
The Barito languages are around twenty Austronesian languages of Indonesia (Borneo), plus Malagasy, the national language of Madagascar, and the Sama–Bajaw languages around the Sulu Archipelago. They are named after the Barito River located in South Kalimantan, Indonesia.
The Greater North Borneo languages are a proposed subgroup of the Austronesian language family. The subgroup historically covers languages that are spoken throughout much of Borneo and Sumatra, as well as parts of Java, and Mainland Southeast Asia. The Greater North Borneo hypothesis was first proposed by Robert Blust (2010) and further elaborated by Alexander Smith. The evidence presented for this proposal are solely lexical. Despite its name, this branch has been now widespread within the Maritime Southeast Asia region.
The Northwest Sumatra–Barrier Islands languages are a group of Malayo-Polynesian languages spoken by the Batak and related peoples in the interior of North Sumatra and by the Nias, Mentawai people, and others on the Barrier islands off the western coast of Sumatra, Indonesia.
The Malayo-Sumbawan languages are a proposed subgroup of the Austronesian languages that unites the Malayic and Chamic languages with the languages of Java and the western Lesser Sunda Islands, except for Javanese. If valid, it would be the largest demonstrated family of Malayo-Polynesian outside Oceanic. The Malayo-Sumbawan subgroup is however not universally accepted, and is rejected e.g. by Blust (2010) and Smith (2017), who supported the Greater North Borneo and Western Indonesian hypotheses. In a 2019 paper published in Oceanic Linguistics, Adelaar accepted both of these groupings, in addition to Smith's (2018) redefinition of Barito languages as forming a linkage.
The Bali–Sasak–Sumbawa languages are a group of closely related languages spoken in Indonesia in the western Lesser Sunda Islands. The three languages are Balinese on Bali, Sasak on Lombok, and Sumbawa on western Sumbawa.
The South Sulawesi languages are a subgroup of the Austronesian language family. They are primarily spoken in the Indonesian provinces of South Sulawesi and West Sulawesi, with a small outlying pocket in West Kalimantan.
On the Indonesian island of Sulawesi, 114 native languages are spoken, all of which belong to the Malayo-Polynesian subgroup of the Austronesian language family. With a total number of 17,200,000 inhabitants, Sulawesi displays a high linguistic diversity when compared with the most densely populated Indonesian island Java, which hosts 4–8 languages spoken by 145,100,000 inhabitants.
The Greater Central Philippine languages are a proposed subgroup of the Austronesian language family, defined by the change of Proto-Malayo-Polynesian *R to *g. They are spoken in the central and southern parts of the Philippines, eastern and western parts of Sabah, Malaysia and in northern Sulawesi, Indonesia. This subgroup was first proposed by Robert Blust (1991) based on lexical and phonological evidence, and is accepted by most specialists in the field.
The Proto-Philippine language is a reconstructed ancestral proto-language of the Philippine languages, a proposed subgroup of the Austronesian languages which includes all languages within the Philippines as well as those within the northern portions of Sulawesi in Indonesia. Proto-Philippine is not directly attested to in any written work, but linguistic reconstruction by the comparative method has found regular similarities among languages that cannot be explained by coincidence or word-borrowing.
Rejang is an Austronesian language predominantly spoken by the Rejang people in southwestern parts of Sumatra (Bengkulu), Indonesia. There are five dialects, spread from mountainous region to the coastal region of Bengkulu, including the Musi (Musai) dialect, the Lebong dialect, the Kebanagung dialect, the Rawas (Awes) dialect, and the Pesisir dialect.
