Ethnologue: Languages of the World is an annual reference publication in print and online that provides statistics and other information on the living languages of the world. It is the world's most comprehensive catalogue of languages. It was first issued in 1951, and is now published by SIL International, an American evangelical Christian non-profit organization.
A language family is a group of languages related through descent from a common ancestor, called the proto-language of that family. The term family is a metaphor borrowed from biology, with the tree model used in historical linguistics analogous to a family tree, or to phylogenetic trees of taxa used in evolutionary taxonomy. Linguists thus describe the daughter languages within a language family as being genetically related. The divergence of a proto-language into daughter languages typically occurs through geographical separation, with different regional dialects of the proto-language undergoing different language changes and thus becoming distinct languages over time.
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.
An unclassified language is a language whose genetic affiliation to other languages has not been established. Languages can be unclassified for a variety of reasons, mostly due to a lack of reliable data but sometimes due to the confounding influence of language contact, if different layers of its vocabulary or morphology point in different directions and it is not clear which represents the ancestral form of the language. Some poorly known extinct languages, such as Gutian and Cacán, are simply unclassifiable, and it is unlikely the situation will ever change.
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).
The Eleman languages are a family spoken around Kerema Bay, Papua New Guinea.
The Duna–Pogaya (Duna–Bogaia) languages are a proposed small family of Trans–New Guinea languages in the classification of Voorhoeve (1975), Ross (2005) and Usher (2018), consisting of two languages, Duna and Bogaya, which in turn form a branch of the larger Trans–New Guinea family. Glottolog, which is based largely on Usher, however finds the connections between the two languages to be tenuous, and the connection to TNG unconvincing.
The Ngbandi language is a dialect continuum of the Ubangian family spoken by a half-million or so people in the Democratic Republic of Congo and in the Central African Republic. It is primarily spoken by the Ngbandi people, which included the dictator of what was then known as Zaire, Mobutu Sese Seko.
The Orya–Tor languages are a family of just over a dozen Papuan languages spoken in Western New Guinea, Indonesia.
The Marañón River basin, at a low point in the Andes which made it an attractive location for trade between the Inca Empire and the Amazon basin, once harbored numerous languages which have been poorly attested or not attested at all. Those of the middle reaches of the river, above the Amazon basin, were replaced in historical times by Aguaruna, a Jivaroan language from the Amazon which is still spoken there. The languages further upriver are difficult to identify, due to lack of data. The region was multilingual at the time of the Conquest, and the people largely switched to Spanish rather than to Quechua, though Quechua also expanded during Colonial times.
Manta is a Grassfields language of Cameroon.
Senara (Niangolo), one of a cluster of languages called Senari, is a Senufo language of Burkina Faso and Mali.
Kĕnaboi is an extinct unclassified language of Negeri Sembilan, Malaysia that may be a language isolate or an Austroasiatic language belonging to the Aslian branch. It is attested in what appears to be two dialects, based on word lists of about 250 lexical items, presumably collected around 1870–90.
Parsi has been used as a name for several languages of South Asia and Iran, some of them spurious:
Spurious languages are languages that have been reported as existing in reputable works, while other research has reported that the language in question did not exist. Some spurious languages have been proven to not exist. Others have very little evidence supporting their existence, and have been dismissed in later scholarship. Others still are of uncertain existence due to limited research.
There have been a number of Arabic-based pidgins and creoles throughout history, including a number of new ones emerging today. These may be broadly divided into the Sudanic pidgins and creoles, which share a common ancestry, and incipient immigrant pidgins. Additionally, Maridi Arabic may have been an 11th-century pidgin.
Harald Hammarström is a Swedish linguist. He is currently an Associate Senior Lecturer at Uppsala University. Hammarström is especially known for his extensive work on curating Glottolog, a bibliographic database of the world's languages.
