Nǁng ([ᵑǁŋ]) orNǁŋǃke is aalmost extinctTuu language spoken in South Africa. It is commonly known by the ambiguous name of itsonly spoken dialect^{[citation needed]}Nǀuu (Nǀhuki); theǀʼAuni name for the Nǀuu,ǂKhomani, is used by the South African government. Nǁng had been thought extinct and was no longer spoken on a daily basis when rediscovered, as the two dozen elderly speakers lived in different villages and the younger generations had shifted to theKhoekhoe language. As of October 2025, only one speaker of the Nǀuu dialect remains, the rest of the population having shifted toKhoekhoe andAfrikaans.^[2][4]

Nǁng belongs to theTuu (Taa–ǃKwi) language family, with extinctǂUngkue being its closest relative andTaa its closest living relative.

The two recent dialects are a western/northwestern one, to which the name Nǀuu (Nǀhuki) is sometimes restricted, and an eastern dialect from the area ofLangeberg, ǁʼAu. As of 2010, most remaining speakers spoke Nǀuu dialect, and this was the name Nǁng appeared under when it was rediscovered. However, two spoke the ǁʼAu dialect and rejected the label 'Nǀuu'.

The easiest of the various names for English speakers to pronounce isNǀuu. The letter that looks like a vertical bar (sometimes substituted with a slash) represents adental click like the English interjectiontsk! tsk! (tut! tut!) used to express pity or shame, but nasalized; "Nǀuu" is pronounced likenoo, with atsk! in the middle of the[n]. The double-vertical-bar in "Nǁng" is a (single)lateral click, pronounced like thetchick! used to spur on a horse; the name is pronounced like theng ofsung with this click in it.

The wordnǀuu/ᵑǀùú/ is actually a verb, 'to speak a Bushman language', possibly fromKhoekhoe.Nǀhuki is adeverbal, 'a Bushman language'.^[5] The people call themselvesNǁŋ-ǂe/ᵑǁŋ̀ŋ̀ǂé/ 'Nǁng people', and Westphal believes this may be the term recorded by Bleek and variously rendered in the literature asǁNg ǃʼe, ǁn-ǃke, ǁŋ.ǃke.^{[note 1]}

The nameNǀusan is an ambiguous Khoekhoe exonym, and is used for several Tuu languages. Traill says that theǀʼAuni call their languageNǀhuki, but others have recorded their name for their language asǀʼAuo, and both Westphal and Köhler state thatNǀhuki (Nǀhuci, nǀɦuki) is a variety of Nǁng. It is possible the languages have gotten mixed up in the literature.^[6]

Güldemann (2017) lists the following pre-democracydoculects as being Nǁng.^[5]

Nǁng prospered through the 19th century, but encroaching non-ǃKwi languages andacculturation threatened it, like most other Khoisan languages. The language was mainly displaced byAfrikaans andNama, especially after speakers started migrating to towns in the 1930s and found themselves surrounded by non-Nǁng-speaking people. In 1973 their language was declared extinct, and the remaining Nǁnǂe ("ǂKhomani") were evicted from theKalahari Gemsbok National Park.

In the 1990s, linguists located 101-year-oldElsie Vaalbooi, who could still speak Nǁng.Anthony Traill interviewed her in 1997. TheSouth African San Institute soon became involved in the pursuit of information on the Nǁng language, and with the help of Vaalbooi they tracked down 25 other people scattered by the eviction who were able to speak or at least understand the language.Thabo Mbeki handed over 400 km² of land to the Nǁnǂe in 1999, and 250 km² of land within the park in 2002. Vaalbooi came up with the Nǁng motto ofSa ǁʼa ǃainsi uinsi "We move towards a better life" for her rehabilitated people. This was also adopted as the official motto for theNorthern Cape Province. At the time there were twenty elderly speakers, eight of whom lived in theWestern Cape province signed over to them. As of 2007, fewer than ten were still alive in South Africa, and a few more in Botswana; none live with another speaker, and their daily languages areKhoekhoe andTswana, respectively. In 2013 there were three speakers in theUpington area and two inOlifantshoek (ǁʼAu), speaking the western and eastern dialects, respectively. The younger generations of ǂKhomani are proud Nama speakers and have little affinity to Nǁng.

Recent research on Nǁng led byAmanda Miller ofCornell University has helped describe the physics of itsclicks, leading to abetter understanding of click sounds in general.^[7]

Efforts to perpetuate the Nǁng language continued in 2017^[8] and in 2021.^[9] The first Nǁng children's book, !Qhoi n|a Tjhoi (Tortoise and Ostrich), was written by Katrina Esau, one of the two surviving speakers at the time, in May 2021.^[10] In June 2021, her brother Simon Sauls died, leaving 88-year-old Katrina Esau as the last speaker of the language.^[2] Esau had opened a school with her granddaughter to teach the language to children, but it was vandalized during the COVID pandemic and abandoned.^[3] As of October 2025, aged 92, Esau still teaches the language.^[11][4]

Nǁng has one of the more complex sound inventories of the world's languages. Mostlexical words consist of aphonological foot with twomoras (tone-bearing units). The first mora must start with a consonant (CV). The second mora may be a single vowel (V), a nasal consonantm orn (N), or one of a drastically reduced number of consonants plus a vowel (cV). That is, lexical roots, not counting sometimes lexicalized CV prefixes and suffixes, are typically CVcV, CVV, CVN, though there are also a few which are CV, as well as longer words of two phonological feet: CVCV, where the second C is not one of the reduced set of consonants but cannot be a click,^{[note 2]} CVCVN, CVVCV, CVNCV, CVVCVN, CVNCVN, CVcVCV, CVVCVcV.Grammatical words tend to be CV or V.^[12]

There are occasional exceptions to these patterns in ideophonic words such as/ɟùɾùkúɟúí-sí/ 'Namaqua sandgrouse' (CVcVCVCVV + suffix) and historically reduplicated words with clicks such as/ǁáḿǁàm̀/ 'to talk'.

Like most languages in southern Africa, Nǁng has five vowel qualities. These may occurstrident andnasalized. A word may have two adjacent vowels, which resemble a long vowel or diphthong.

The strident vowels are thought to have the phonation calledharsh voice. They are strongly pharyngealized, and for some speakers involve low-frequency trilling that presumably involves thearyepiglottic fold. The four strident vowel qualities (there is no stridenti) are rather different from the non-strident vowels, as is common when a vowel ispharyngealized.

Nǁng is the only Khoisan language known to have a strident front vowel,/e𐞴/, though this is rare, occurring in only two known words, zeqe/zḛ̰́é/ 'to fly' and ǂʻheqbe/ᵑ̊ǂḛ̰̀βé/ 'man's loincloth'. The lack of a nasalized equivalent is thought to be anaccidental gap or simply unattested due to the small number of known words.

The tone-bearing segment may be a syllabic nasal,/ŋ̍/, rather than a vowel, as in the name Nǁng.

Only certain sequences of vowels may occur in a bimoraic foot, regardless of whether there is an intervening consonant. (That is, the permitted vowels are the same whether a word is CVcV or CVV.) If the first vowel is any variety (nasal, strident, etc.) of/i,e,ŋ̍/, then the second vowel must be identical. If the first vowel is/a/, then the second may be anything but/ŋ̍/. If the first vowel is/o/ or/u/, then the second may be either/a/ or a vowel of the sameheight: that is,oa, oo, oe; ua, uu, ui. The vowels must be both oral or both nasal; nasal vowels cannot follow anasal stop (though they may follownasal clicks). Only the first vowel may be strident.

Front vowels can only follow the click typesǀ andǂ (theback-vowel constraint), with a single known exception,[ᵑǁˀé] 'to go'. Front vowels and strident vowels may also not follow[χ], whether an affricate release or a fricative, with the exception of three female kin terms where the second syllable is/χè/. As with the lack of strident front vowels, there are thus a small number of exceptions for these constraints with/e/, but none with/i/.

Nǁng moras may carry a high or lowtone, /H/ or /L/. A typical lexical word consists of two moras, and so may have a high (HH), low (LL), rising (LH), or falling (HL) tone.

Monomoraic lexical roots, such as/cú/ 'mouth', are high- rather than low-tone by a 5–1 margin. CVV and CVN roots are HH, HL, and LH with about equal frequency, with LL slightly less common. However, half of all CVcV roots are LH, making it markedly frequent, while only 5% are HL. In an additional CV foot the distribution of H and L is approximately equal; an additional CVN or CVcV foot may pattern like an initial foot, but they are too infrequent to be sure.

The majority of Nǁng consonants areclicks. It was once thought that Khoisan languages distinguishvelar anduvular clicks, but recent research into Nǁng, and reevaluation of the data onǃXóõ, indicates that, for these languages at least, the distinction is one of pure clicks versus click–plosivecontours.

"(?)" marks possible accidental gaps;^[13] these consonants might be expected based on their occurrence in neighboring languages with similar phonologies, but are expected to be rare, and may occur in Nǁng words that have not been recorded.

What were historically initial alveolar occlusives have become pre-palatal in lexical words. Among grammatical words in the western dialect there is a single exception,ná 'I'; in the eastern dialect even that has merged, forɲá 'I'.

Onlysonorants may occur as the medial consonant of a phonological foot./l/ is only known from three words. The oral sonorants do not occur in initial position.

These are simple clicks. The traditional term "velaric" is something of a misnomer, for the rear articulation is further back than the velum, and indeed further back than Nǁng/q/. Miller et al. prefer the term "lingual" for thisairstream mechanism; they also reject the existence of click "accompaniments", using the IPA symbols to represent both points of articulation rather than solely the anterior articulation. Besides being motivated phonetically, this has the benefit of better illustrating the parallels between clicks and pulmonic consonants.

In the above rubric, the first element of the name is the forward articulation, and the second is the rear articulation.

These areairstream contour consonants, which start off with a lingual (velaric) airstream mechanism and finish with a pulmonic airstream (whereas affricates are manner contour consonants, starting as plosives and finishing as fricatives). Traditionally, these were considered to be uvular clicks, because the uvular or pharyngeal closure is audible, but in fact the rear closure of all Nǁng clicks is uvular or pharyngeal. (The distinction between uvular and pharyngeal is not represented here.) Effectively, in these clicks the release of the rear articulation is delayed, so that there is a double release burst, the forward (lingual) release followed by the rear (pulmonic) release.

These differ from the previous consonants in that the second, rear release is an ejective.
