Main articles: Dental click and nasal click

The dental nasal click is a click consonant found primarily among the languages of southern Africa. The symbol in the International Phonetic Alphabet for a nasal dental click with a velar rear articulation is ⟨ŋ͡ǀ⟩ or ⟨ŋ͜ǀ⟩, commonly abbreviated to ⟨ŋǀ⟩, ⟨ᵑǀ⟩ or ⟨ǀ̃⟩; a symbol abandoned by the IPA but still preferred by some linguists is ⟨ŋ͡ʇ⟩ or ⟨ŋ͜ʇ⟩, abbreviated ⟨ŋʇ⟩, ⟨ᵑʇ⟩ or ⟨ʇ̃⟩. For a click with a uvular rear articulation, the equivalents are ⟨ɴ͡ǀ, ɴ͜ǀ, ɴǀ, ᶰǀ⟩ and ⟨ɴ͡ʇ, ɴ͜ʇ, ɴʇ, ᶰʇ⟩. Sometimes the accompanying letter comes after the click letter, e.g. ⟨ǀŋ⟩ or ⟨ǀᵑ⟩; this may be a simple orthographic choice, or it may imply a difference in the relative timing of the releases.

Features

Features of the dental nasal click:

• The airstream mechanism is lingual 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 articulation is dental, 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 a nasal consonant, which means air is allowed to escape through the nose, either exclusively (nasal stops) or in addition to through the mouth.
• 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.

Occurrence

Dental nasal clicks are found primarily in the various Khoisan language families of southern Africa and in some neighboring Bantu languages, such as Yeyi and Fwe.

Main article: Glottalized click

All Khoisan languages, and a few Bantu languages, have glottalized nasal clicks. These are formed by closing the glottis so that the click is pronounced in silence; however, any preceding vowel will be nasalized.

Hadza	tacce	[taᵑǀˀe] = [taᵑʇˀe]	'rope'
Khoekhoe	ǀoroǀoro	[ᵑǀˀòɾőᵑǀˀòɾȍ] = [ᵑʇˀòɾőᵑʇˀòɾȍ]	'to wear s.t. out'
