The voiced dental click is a click consonant found primarily among the languages of southern Africa.[1] The symbol in the International Phonetic Alphabet for a voiced dental click with a velar rear articulation is ⟨ɡ͡ǀ⟩ or ⟨ɡ͜ǀ⟩, commonly abbreviated to ⟨ɡǀ⟩, ⟨ᶢǀ⟩ or ⟨ǀ̬⟩; a symbol abandoned by the IPA but still preferred by some linguists is ⟨ɡ͡ʇ⟩ or ⟨ɡ͜ʇ⟩, abbreviated ⟨ɡʇ⟩, ⟨ᶢʇ⟩ or ⟨ʇ̬⟩. For a click with a uvular rear articulation, the equivalents are ⟨ɢ͡ǀ, ɢ͜ǀ, ɢǀ, 𐞒ǀ⟩ and ⟨ɢ͡ʇ, ɢ͜ʇ, ɢʇ, 𐞒ʇ⟩.
Sometimes the accompanying letter comes after the click letter, e.g. ⟨ǀɡ⟩ or ⟨ǀᶢ⟩; this may be a simple orthographic choice, or it may imply a difference in the relative timing of the releases.[2]
In languages which use the Bantu letters for clicks, this is most commonly written ⟨gc⟩, but it is written ⟨dc⟩ in those languages that use ⟨g⟩ for the uvular fricative.
The airstream mechanismislingual ingressive (also known as velaric ingressive), which means a pocket of air trapped between two closures is rarefied by a "sucking" action of the tongue, rather than being moved by the glottis or the lungs/diaphragm. The release of the forward closure produces the "click" sound. Voiced and nasal clicks have a simultaneous pulmonic egressive airstream.
Its place of articulationisdental, which means it is articulated with either the tip or the blade of the tongue at the upper teeth, termed respectively apical and laminal. Note that most stops and liquids described as dental are actually denti-alveolar.
Its phonation is voiced, which means the vocal cords vibrate during the articulation.
It is an oral consonant, which means air is allowed to escape through the mouth only.
It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
