Glottolog is a free online bibliographic database of the world's languages. In addition to listing linguistic materials (grammars, articles, dictionaries) describing individual languages, the database also contains the most up-to-date language affiliations based on the work of expert linguists.


Glottolog was first developed and maintained at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and between 2015 and 2020 at the Max Planck Institute for the Science of Human History in Jena, Germany). Its main curators include Harald Hammarström and Martin Haspelmath.


Sebastian Nordhoff and Harald Hammarström established the Glottolog/Langdoc project in 2011. [1] [2] The creation of Glottolog was partly motivated by the lack of a comprehensive language bibliography, especially in Ethnologue. [3]

Glottolog provides a catalogue of the world's languages and language families and a bibliography on individual languages. It differs from Ethnologue in several respects:

Language names used in the bibliographic entries are identified by ISO 639-3 code or Glottolog's own code (Glottocode). External links are provided to ISO, Ethnologue and other online language databases

The latest version is 4.8, released under the Creative Commons Attribution 4.0 International License in July 2023.

It is part of the Cross-Linguistic Linked Data project hosted by the Max Planck Institute for the Science of Human History. [4]

Language families

Glottolog is more conservative in its classification than other databases in establishing membership of languages and families given its strict criteria for postulating larger groupings. On the other hand, the database is more permissive in terms of considering unclassified languages as isolates. Edition 4.8 lists 421 spoken language [note 2] families and isolates as follows: [5]

Creoles are classified with the language that supplied their basic lexicon.

In addition to the families and isolates listed above, Glottolog uses several non-genealogical families for various languages: [6]


  1. See for example the bookkeeping section for ISO languages that Glottolog has deemed to be spurious distinctions.
    This discrimination does not apply to dialects, many of which have been inherited from MultiTree or other sources without verification.
  2. Sign languages are listed together, including those grouped typologically as village sign languages, as are pidgins and unclassified languages, but without a claim that they are necessarily related.
  3. Geographic regions include "Papunesia" (a portmanteau of Papua (New Guinea) and Austronesia), which refers to the islands of Insular Southeast Asia and Oceania, excluding Australia. Here it is replaced with 'Oceania'.

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.

<span class="mw-page-title-main">Papuan languages</span> Non-Austronesian languages of New Guinea and adjacent islands

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 by around 4 million people. 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 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 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.

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.
