The following languages are listed as unclassified by the Ethnologue (17th edition), though in their descriptions some are identified with an established family, or have been retired as spurious. Since the 15th edition, several other unclassified languages were found to be related to known languages once better data was collected, and some, such as Amikoana and Miarrã, were found to be spurious and their ISO codes were retired. (See spurious languages.) Languages which became extinct before 1950 are the purview of Linguist List and are being gradually removed from Ethnologue; they are listed as an addendum to this page.
There are 48 unclassified languages in the 25th edition of Ethnologue published in 2022.
All cants:
These languages became extinct before 1950 and their ISO codes are not, or are no longer, maintained by SIL. Maintenance of additional languages extinct before 1950 is being gradually shifted from SIL to Linguist List.
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.
The number of languages natively spoken in Africa is variously estimated at between 1,250 and 2,100, and by some counts at over 3,000. Nigeria alone has over 500 languages, one of the greatest concentrations of linguistic diversity in the world. The languages of Africa belong to many distinct language families, among which the largest are:
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.
ISO 639-3:2007, Codes for the representation of names of languages – Part 3: Alpha-3 code for comprehensive coverage of languages, is an international standard for language codes in the ISO 639 series. It defines three-letter codes for identifying languages. The standard was published by International Organization for Standardization (ISO) on 1 February 2007.

South Levantine Arabic was defined in the ISO 639-3 international standard for language codes as a distinct Arabic variety, under the ajp
code. It was reported by Ethnologue as being spoken in the Southern Levant: Palestinian Territories, Israel, and most of Jordan.
Chakato is a West Chadic language spoken in Plateau State, Nigeria. It was identified by Roger Blench in 2016. It is spoken by about 500 people in one village, Dokan Tofa, which is located on the Jos-Shendam road in Plateau State. Blench (2017) suggests that Chakato may be related to spurious records of the Jorto language. Chakato speakers claim that their language is closely related to Goemai.
Daza or Dazawa is listed by Blench (2006) as a Chadic language within the Bole group, spoken in a few villages of Darazo LGA, Bauchi State, Nigeria. It was confirmed to exist in 2021. The language is nearly extinct with only elderly speakers speaking the language. Native speakers have shifted to Hausa.
Pasto is a purported Barbacoan language that was spoken by Indigenous people of Pasto, Colombia and Carchi Province, Ecuador. It is now extinct.
The Agariya language is a spurious language said to be spoken by the Agariya people, a community found in northern Chhattisgarh, western Odisha and eastern Madhya Pradesh. Although recorded in Ethnologue with an ISO code, the language is declared as 'spurious' by Glottolog and its existence was explicitly denied by noted scholar of tribal traditions Verrier Elwin, and more recently by linguist Felix Rau and Paul Sidwell. This was primarily due to suspicions of the conflating of various different 'Agariya' tribes with different dialects. Agariya shares similarities to languages such as Chhattisgarhi, Odia, and Sambalpuri. Agharia as the language claims to descent from the mixing of the languages Laria and Odia and Sambalpuri themselves, when the Laria language came in contact with Odia and Sambalpuri Dialects, leading to lexical borrowing, making so that a native speaker has only retained about 5-6 percent of the original word list.
The Jukunoid languages are a branch of the Benue-Congo languages spoken by the Jukun and related peoples of Nigeria and Cameroon. They are distributed mostly throughout Taraba State, Nigeria and surrounding regions.
The Orya–Tor languages are a family of just over a dozen Papuan languages spoken in Western New Guinea, Indonesia.
Kaure is a Papuan language of West Papua. It is spoken in the villages of Lereh, Harna, Wes, Masta, and Aurina.
The Hill Nubian languages, also called Kordofan Nubian, are a dialect continuum of Nubian languages spoken by the Hill Nubians in the northern Nuba Mountains of Sudan.
Ngbinda is a poorly documented Congolese Bantu language of uncertain affiliation. Prior to 1975 it had also been spoken in southern Sudan.
Iyive, also referred to as Uive, Yiive, Ndir, Asumbos, is a severely endangered Bantoid language spoken in Nigeria and Cameroon. The ethnic group defined by use of this language is the Ndir.
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.
Glottolog is an open-access online bibliographic database of the world's languages. In addition to listing linguistic materials describing individual languages, the database also contains the most up-to-date language affiliations based on the work of expert linguists.
