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.
The Nilo-Saharan languages are a proposed family of around 210 African languages spoken by somewhere around 70 million speakers, mainly in the upper parts of the Chari and Nile rivers, including historic Nubia, north of where the two tributaries of the Nile meet. The languages extend through 17 nations in the northern half of Africa: from Algeria to Benin in the west; from Libya to the Democratic Republic of the Congo in the centre; and from Egypt to Tanzania in the east.
The Northeast Caucasian languages, also called East Caucasian, Nakh-Daghestani or Vainakh-Daghestani, or sometimes Caspian languages, is a family of languages spoken in the Russian republics of Dagestan, Chechnya and Ingushetia and in Northern Azerbaijan as well as in Georgia and diaspora populations in Western Europe and the Middle East. According to Glottolog, there are currently 36 Nakh-Dagestanian languages.
A language isolate is a language that has no demonstrable genetic relationship with any other languages. Basque in Europe, Ainu in Asia, Sandawe in Africa, Haida and Zuni in North America, Kanoê in South America, Tiwi in Australia and Burushaski in Pakistan are all examples of language isolates. The exact number of language isolates is yet unknown due to insufficient data on several languages.
The Nubian languages are a group of related languages spoken by the Nubians. In the past, Nubian languages were spoken throughout much of Sudan, but as a result of Arabization they are today mostly limited to the Nile Valley between Aswan and Al Dabbah. In the 1956 Census of Sudan there were 167,831 speakers of Nubian languages. Nubian is not to be confused with the various Nuba languages spoken in villages in the Nuba mountains and Darfur.
The Songhay, Songhai or Ayneha languages are a group of closely related languages/dialects centred on the middle stretches of the Niger River in the West African countries of Mali, Niger, Benin, Burkina Faso and Nigeria. In particular, they are spoken in the cities of Timbuktu, Djenné, Niamey, Gao, Tillaberi, Dosso, Parakou, Kandi, Natitingou, Djougou, Malanville, Gorom-Gorom, In-Gall and Tabelbala. They have been widely used as a lingua franca in that region ever since the era of the Songhai Empire. In Mali, the government has officially adopted the dialect of Gao as the dialect to be used as a medium of primary education.
The Yeniseian languages are a family of languages that are spoken by the Yeniseian people in the Yenisei River region of central Siberia. As part of the proposed Dené–Yeniseian language family, the Yeniseian languages have been argued to be part of "the first demonstration of a genealogical link between Old World and New World language families that meets the standards of traditional comparative-historical linguistics". The only surviving language of the group today is Ket.
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.
This is a list of different language classification proposals developed for the Indigenous languages of the Americas. The article is divided into North, Central, and South America sections; however, the classifications do not correspond to these divisions.
The Association québécoise de linguistique is an academic organization devoted to the scientific study of human language, and is a professional society for Francophone linguistic researchers in North America and beyond.
The Sal languages, also known as the Brahmaputran languages, are a branch of Tibeto-Burman languages spoken in northeast India, as well as parts of Bangladesh, Myanmar (Burma), and China.
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 French Sign Language or Francosign family is a language family of sign languages which includes French Sign Language and American Sign Language.
There have been various classification schemes for Southeast Asian languages.
Armenian Sign Language is the deaf sign language of Armenia.
Massep is a poorly documented Papuan language spoken by fewer than 50 people in the single village of Masep in West Pantai District, Sarmi Regency, Papua. Despite the small number of speakers, however, language use is vigorous. It is surrounded by the Kwerba languages Airoran and Samarokena.
Duli is an extinct Adamawa language of northern Cameroon.
The Danish Sign Language family comprises three languages: Danish Sign Language, Norwegian Sign Language and Icelandic Sign Language. It itself is a sub-language family within the larger French Sign Language family.
