Dahalo is anendangeredCushitic language spoken by around 500–600 Dahalo people on the coast of Kenya, near the mouth of theTana River. Dahalo is unusual among the world's languages in using all fourairstream mechanisms found in human language:clicks,implosives,ejectives, andpulmonic consonants.
While the language is known primarily as "Dahalo" to linguists, the term itself is an exonym supposedly used byAweer speakers that itself essentially means “stupid” or “worthless.”[3] The speakers themselves refer to the language asnumma guhooni.
The Dahalo, former elephant hunters, are dispersed amongSwahili and other Bantu peoples, with no villages of their own, and are bilingual in those languages. Children no longer learn the language, which would make itmoribund, and it may be extinct.[1]
Dahalo has a highly diverse sound system using all fourairstream mechanisms found in human language:clicks,ejectives, andimplosives, as well as the universalpulmonic sounds. Nguni languages such as Xhosa and Zulu also use all four airstream mechanisms, although the ejective consonants in these languages are weak, and vary between speakers.
In addition, Dahalo makes a number of uncommon distinctions. It contrastslaminal andapical stops, as in languages of Australia and California;epiglottal andglottal stops and fricatives, as in the Mideast, the Caucasus, and the American Pacific Northwest; and is perhaps the only language in the world to contrastalveolar lateral andpalatal lateral fricatives and affricates.
It is suspected that the Dahalo may have once spoken aSandawe- orHadza-like language, and that they retained clicks in some words when theyshifted to Cushitic, because many of the words with clicks are basic vocabulary. If so, the clicks represent asubstratum.
Dahalo is also calledSanye, a name shared with neighboringWaata, also spoken by former hunter-gatherers. The Waata may once have spoken a language more like Dahalo before shifting toOromo.
The classification of Dahalo is obscure. Traditionally included inSouth Cushitic, Tosco (1991) argues instead that it isEast Cushitic,[4] and Kießling (2001) agrees that it has too many Eastern features to be South Cushitic.[5]
Dahalo has, by all accounts, a large consonant inventory. 62 consonants are reported by Maddieson et al. (1993),[6] whereas Tosco (1991) recognizes 50.[4] The inventory according to the former is presented below:
Tosco's account differs in not including the labialized clicks, the palatal laterals, and the voiceless prenasalized consonants (on which see below), analyzing/t͇ʼ/ as/tsʼ/, and adding/dɮ/,/ʄ/ and/v/ (which Maddieson et al. believe to be an allophone of/w/).
This typologically extraordinary inventory appears to result from extended contact influence from substratal and superstratal languages, due to long-running bilinguality. Only 27 consonants (shown inbold) are found in the final position of verbal stems, which Tosco suggests represents the inherited Cushitic component of the consonant inventory.
Several phonemes can be shown to be recent intrusions into the language through loanwords:[4]
Additionally, several consonants are marginal in their occurrence. Five are only attested in a single root:
Less than five examples each are known of/ᵑʇˀʷ,tʃ,tsʼ,tʃʼ,kʷʼ,dɮ,ʄ,ⁿd͇,ⁿdz/.
The prenasalized voiceless stops have been analyzed as syllabic nasals plus stops by some researchers. However, one would expect this additional syllable to give Dahalo words additionaltonic possibilities, as Dahalo pitch accent is syllable-dependent (see below), and Maddieson et al. report that this does not seem to be the case. Tosco (1991)[4] analyzes these asconsonant clusters, on the grounds that Dahalo allows long vowels inopen syllables only, and that while words such as /tʃaːⁿda/ 'finger' can be found, only short vowels occur preceding the alleged voiceless prenasalized consonants. He additionally reports fricative and glottalized clusters:/nf/,/nt̪ʼ/,/ntɬʼ/ and/nʔ/.
The laminal coronals aredenti-alveolar, whereas the apicals are alveolar tending towardpost-alveolar.
When geminate, the epiglottals are a voiceless stop and fricative. In utterance-initial position they may be a partially voiced (negativevoice onset time) stop and fricative. However, as singletons between vowels,/ʡ/ is aflap or even an approximant with weak voicing, whereas/ʜ/ is a fully voiced approximant. Otherobstruents are similarly affected intervocalically, though not to the same degree.
/bd̪d͇/ are often opened to approximants[β̞ð̞ð͇˕] or weak fricatives[βðð͇] between vowels (sometimes a retraction diacritic is used as in ⟨d̠⟩, serving merely to emphasize that it is further back than/d̪/). Initially, they and/ɡ/ are often voiceless, whereas/pt̪t͇k/ are fortis (perhaps aspirated)./w̜/ has little rounding.
There is a lot of variability in the voicing of clicks, so this distinction may be being lost. The nasal clicks are nasalized prior to the click release and are voiced throughout; the voiceless clicks usually have about 30ms ofvoice onset time, but sometimes less. There is no voiceless nasal airflow, but following vowels may have a slightly nasalized onset. Thus these clicks are similar to glottalized nasal clicks in other languages. Voiceless clicks are much more common than voiced clicks.
Dahalo has a symmetric 5-vowel system of pairs of short and longvowels, totaling 10 vowels:
| Front | Back | |
|---|---|---|
| High | i /iː | u /uː |
| Mid | e /eː | o /oː |
| Low | a /aː | |
Dahalo words are commonly 2–4 syllables long. Syllables are exclusively of theCV pattern, except that consonants may begeminate between vowels. As with many otherAfroasiatic languages, gemination is grammatically productive. Voiced consonants partially devoice, and prenasalized stops denasalize when geminated as part of a grammatical function. However, lexical prenasalised geminate stops also occur.
The consonants/b/ and/d̠/ are systematically excluded from the word-initial position.
(It is likely that the glottals and clicks do not occur as geminates, although only a few words with intervocalic clicks are known, such as/ʜáŋ̊|ana/.)
Dahalo haspitch accent, normally with zero to one high-pitched syllables (rarely more) per root word. If there is a high pitch, it is most frequently on the first syllable; in the case of disyllabic words, this is the only possibility: e.g./ʡani/head,/pʼúʡʡu/pierce.
Dahalo is one of very few languages outside southern Africa to have phonemic clicks (the others beingSandawe andHadza in Tanzania andDamin, a ceremonial register ofLardil formerly spoken onMornington Island in Australia). The clicks in Dahalo are not Cushitic in origin, and may be a remnant of a shift from a non-Cushitic language. Ten Raa shows some slight evidence that speakers of Dahalo once spoke a language similar to Sandawe, which does have clicks.[7] This might explain why clicks are only present in about 40 lexical items, some of which are basic (e.g. "breast," "saliva," and "forest").[8]
Ehret reported that different words had either dental andlateral clicks, while Elderkin reported that these were allophones. It is not clear if an old distinction has merged, or if the place of articulation is variable because there is no distinction to maintain.
