It is best known for its use of click consonants, which make it one of only three languages with clicks outside southern Africa, the others being its Tanzanian neighbor Sandawe and the Cushitic language Dahalo in Kenya[3](https://linguistlist.org/issues/34/1074/) • [4](https://www.asau.ru/files/pdf/2026893.pdf). Despite its fame among linguists, Hadza has no demonstrated relationship to any other language, and its sound system remains one of the more contested in African linguistics[1](https://scholarworks.iu.edu/dspace/items/97d4ad62-8e0f-4aea-a470-61a1b183454d).\n\n| Key fact | Detail |\n|---|---|\n| Classification | Language isolate; Greenberg's (1963) Khoisan assignment is now rejected by specialists[4](https://www.asau.ru/files/pdf/2026893.pdf) • [5](https://aclanthology.org/2024.rail-1.pdf) |\n| Location and speakers | Lake Eyasi area, north-central Tanzania; estimates range from about 1,000 to 2,000 speakers[1](https://scholarworks.iu.edu/dspace/items/97d4ad62-8e0f-4aea-a470-61a1b183454d) • [2](https://eref.uni-bayreuth.de/id/eprint/70167/) |\n| Codes | ISO 639-3: hts; Glottocode: hadz1240[6](https://asjp.clld.org/languages/HADZA) |\n| Sound inventory | 64 consonants (including clicks and ejectives) and 5 vowel qualities with length and marginal nasal contrasts, per a 2026 sketch grammar[7](https://sas.rochester.edu/lin/news/2026-09-24-coburn.html) |\n| Clicks | Four click types (bilabial, dental, alveolar, lateral); recent acoustic work counts 13 click consonants[8](https://demolin.laboratoirephonetiquephonologie.fr/ressources/PDF_Posters/2021/Poster%20ASA%20Hadza.pdf) |\n| Vitality | \"Vulnerable\" per the UNESCO Atlas of the World's Languages in Danger; \"endangered\" per Ethnologue[9](https://zenodo.org/records/7697989) |\n| Recent shift | In 2022 fieldwork, children aged eight and under were found to communicate primarily in Swahili in all but two of the camps visited[9](https://zenodo.org/records/7697989) |\n\n## Classification\n\nHadza was long grouped with the [Khoisan languages](https://www.edgepedia.org/khoisan-languages). Dorothea Bleek, an anthropologist and philologist who studied African click languages, examined the Hadzapi of Tanganyika Territory in 1930 and tentatively suggested a phylogenetic link to the click languages of the San and Nama peoples of southern Africa, a conclusion rejected in subsequent investigations[10](https://ehrafworldcultures.yale.edu/cultures/fn11/documents/013). [Joseph Greenberg](https://www.edgepedia.org/joseph-greenberg)'s 1963 classification of African languages included Hadza with the Khoisan languages, together with neighboring Sandawe, on the basis of the clicks in their consonant inventories[11](https://scholarworks.iu.edu/dspace/bitstreams/4c4c8557-ad10-4779-ad72-40e15de89def/download).\n\nThat assignment did not survive scrutiny. Bonny Sands, a linguist specializing in click languages, was the first to mount a systematic critique of the methodology and evidence in Khoisan-related works, heralding growing skepticism about the classification[4](https://www.asau.ru/files/pdf/2026893.pdf). Specialists now agree that the southern African languages once called Khoisan form three distinct families, Kx'a, Tuu, and Khoe-Kwadi, and that Hadza and Sandawe are isolates[12](https://doi.org/10.1093/hmg/ddaa221). Hadza shows very few convincing links to any other language, including the geographically near Sandawe[3](https://linguistlist.org/issues/34/1074/). Genetic research offers a parallel picture: the Hadza and Sandawe derive a fraction of their ancestry from admixture with a population related to the Khoisan-speaking peoples of southern Africa, supporting an ancient link between the two regions without implying a language family[13](https://arxiv.org/abs/1207.5552).\n\n## Sound system\n\nHadza's consonant inventory is unusually large and typologically uncommon. It includes clicks, ejectives, and lateral obstruents, and the 2026 sketch grammar by Andrew Harvey, Richard Griscom, and Jeremy Coburn counts 64 consonants alongside five vowel qualities that contrast in length, with a marginal nasal contrast[1](https://scholarworks.iu.edu/dspace/items/97d4ad62-8e0f-4aea-a470-61a1b183454d) • [7](https://sas.rochester.edu/lin/news/2026-09-24-coburn.html).\n\n**Clicks.** The language has four click types, bilabial, dental, alveolar, and lateral, which can combine contrastively with aspirated, glottalized, and nasal accompaniments, sometimes in combination[8](https://demolin.laboratoirephonetiquephonologie.fr/ressources/PDF_Posters/2021/Poster%20ASA%20Hadza.pdf). Descriptions of how many clicks Hadza actually contrasts have varied widely: Sands, Maddieson, and Ladefoged described nine, Kirk Miller suggested twelve, and recent acoustic and articulatory data point to thirteen[8](https://demolin.laboratoirephonetiquephonologie.fr/ressources/PDF_Posters/2021/Poster%20ASA%20Hadza.pdf). Earlier work disagreed in the same way; the 1996 phonetic study by Sands, Ian Maddieson, and Peter Ladefoged noted that previous field reports had disagreed on the number and nature of the clicks and used acoustic and articulatory analysis to give a more detailed picture[14](https://doaj.org/article/395d8af6a96c47bebeb3d7a1c3ae26a7).\n\n**Tone and laryngeal contrasts.** The prosodic system long eluded description, with the literature tentatively marking both tone and stress in substantially varying ways[3](https://linguistlist.org/issues/34/1074/). Jeremy Coburn's 2024 [Indiana University](https://www.edgepedia.org/indiana-university) dissertation, based on nine months of fieldwork in 2022 and 3D/4D ultrasound data collected with a Hadza speaker in 2020, develops a systematic analysis of the tone system and highlights typologically unusual tonal phenomena; it also investigates the temporal characteristics of laryngeal contrasts in obstruents, that is, aspiration and glottalization, and a phonemic vowel length distinction[1](https://scholarworks.iu.edu/dspace/items/97d4ad62-8e0f-4aea-a470-61a1b183454d).\n\nSome of the inventory may reflect contact. Linguists Bonny Sands and Kirk Miller have suggested that some click articulations may have been borrowed from other click languages, and that Hadza's initial prenasalized consonants and voiced obstruents other than /b/ appear to be borrowed; even excluding clicks and non-bilabial voiced obstruents, the consonant inventory would still number 41 segments[15](https://refubium.fu-berlin.de/bitstream/fub188/25953/1/249-3-1687-1-10-20191031.pdf).\n\n## Speakers and vitality\n\nThe [Hadza people](https://www.edgepedia.org/hadza-people), often called Hadzabe, traditionally live a semi-nomadic hunter-gatherer lifestyle, and the community includes the last full-time hunter-gatherers in Africa[3](https://linguistlist.org/issues/34/1074/) • [16](https://arc.dbs.org/data/languages/hts/). Nearly all Hadza individuals speak at least two languages: Hadzane at home and Kiswahili, the lingua franca of [East Africa](https://www.edgepedia.org/east-africa), which is the language of trade, school, and dealings with government officials and medical professionals; in the past many also spoke Isanzu or Sukuma, the [Bantu languages](https://www.edgepedia.org/bantu-languages) of neighboring groups[17](https://pmc.ncbi.nlm.nih.gov/articles/PMC11194998/) • [18](https://dhcp-128-171-46-84.its.hawaii.edu/lang/605).\n\nThe language is classified as \"vulnerable\" by the UNESCO Atlas of the World's Languages in Danger and \"endangered\" by [Ethnologue](https://www.edgepedia.org/ethnologue)[9](https://zenodo.org/records/7697989). Intergenerational transmission was robust in most Hadza communities until recently, but fieldwork in 2022 identified a nascent shift among children aged eight and under, who in all but two of the camps visited communicated primarily in Swahili among agemates and in response to older speakers[9](https://zenodo.org/records/7697989). The community is aware of this shift, and members have begun grassroots efforts to combat language loss[9](https://zenodo.org/records/7697989).\n\n## Documentation and revitalization\n\nHadza was poorly documented for decades; one review noted that although the Hadza are among the anthropologically most intensively studied peoples, documentation and description of the language remained insufficient[4](https://www.asau.ru/files/pdf/2026893.pdf). That has begun to change. An Endangered Languages Documentation Programme project led by Richard Griscom, funded with £141,620.48 and begun in January 2015, worked with Hadza community members to build a corpus of naturalistic and elicited speech recordings and to document linguistic variation and language contact across the traditional Hadza sub-regions[19](https://cultureincrisis.org/projects/documenting-hadza-language-contact-and-variation). The resulting Endangered Languages Archive deposit, assembled with Andrew Harvey, contains audio-visual material largely collected by community members themselves and constitutes the first and only open access documentary record of the language[2](https://eref.uni-bayreuth.de/id/eprint/70167/).\n\nTwo recent publications consolidate this work. In August 2025, a Hadza alphabet chart created in partnership with Hadza community members was delivered to the community to support teaching, documentation, and language preservation[20](https://www.sas.rochester.edu/lin/news/2025-08-14-coburn.html). In 2026, Harvey, Griscom, and Coburn published \"A sketch of Hadza grammar\" in *Studies in African Linguistics*, the first compact sketch grammar of the language, synthesizing decades of published and unpublished scholarship and presenting the segmental and tonal inventories together with key components of the morphosyntax[7](https://sas.rochester.edu/lin/news/2026-09-24-coburn.html). A Hadza New Testament appeared in 2024[16](https://arc.dbs.org/data/languages/hts/).\n\n## References\n\n1. [Jeremy Richard Coburn (2024). The Hadza Language: Vitality, Phonetics, and Phonology.
