The 'dental clicks' are a family of
click consonants found only in
Africa and in the
Damin ritual jargon of
Australia.
The symbol in the
International Phonetic Alphabet that represents the forward articulation of these sounds is . This must be combined with a symbol for the rear articulation to represent an actual speech sound. Attested dental clicks include:
★ or ''voiceless velar dental click'' (may also be aspirated, ejective, affricated, ''etc.'')
★ or ''voiced velar dental click'' (may also be breathy voiced, affricated, ''etc.'')
★ or ''nasal velar dental click'' (may also be voiceless, aspirated, ''etc.'')
★ or ''voiceless uvular dental click''
★ or ''voiceless uvular dental click'' (commonly prenasalized)
★ or ''nasal uvular dental click''
Prior to 1989, was an accepted IPA representation of the ''voiceless velar dental click''.
Features
Features of dental clicks:
★ Their
manner of articulation is
click, which means they are produced with two articulatory closures in the oral cavity. The pocket of air trapped between the two closures is rarefied by a "sucking" action of the tongue. The release of the forward closure produces the 'click' sound. In the case of the dental clicks, the release is noisy, like an
affricate, rather than sharp like a
plosive. The rear closure may be a plosive, nasal, ejective, or affricate, and have any of several
phonations.
★ The forward
place of articulation is
dental or
alveolar and
laminal, which means it is articulated with the blade of the tongue on the
alveolar ridge or the upper
teeth. The rear place of articulation may be either
velar or
uvular.
★ Dental clicks may be either
oral or
nasal, which means air is allowed to escape either through the mouth or the nose.
★ They are
central consonants, which means they are produced by allowing the airstream to flow over the middle of the tongue, rather than the sides.
★ The
airstream mechanism is
velaric ingressive, which means it is produced by movement of air into the mouth by action of the tongue, rather than by the
glottis or the
lungs.
In English
English does not have the dental click (or any click consonant, for that matter) as a phoneme, but it does occur as an
interjection, usually written ''tsk'' or ''tut'' (and often
reduplicated ''tsk-tsk'' or ''tut-tut''), used to express commiseration, disapproval, or irritation. Note, however, that while these words often represent a dental click and may be pronounced as such, they are also frequently pronounced as or , and in such cases cannot be said to be dental clicks.
In other languages
Dental clicks are common in
Khoisan languages and the neighboring Nguni languages, such as
Zulu and
Xhosa. In the Nguni languages, the
tenuis click is denoted by the letter ''c'', the
murmured click by ''gc'', the
aspirated click by ''ch'', and the
nasal click by ''nc''. The prenasalized clicks are written ''ngc'' and ''nkc''.
The Cushitic language
Dahalo has four clicks, all of them nasalized: .
Hungarian does not have any click consonant as a phoneme, but the dental click does occur as an interjection, usually written ''cöccögés'' [], used to express commiseration, disapproval, or irritation.
German uses the dental click in the exact same way as English, though it is usually rendered ''ts'' or ''tss'' in writing.
