The dental nasal click is a click consonant found primarily among the languages of southern Africa. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ǀ̃⟩ or ⟨ᵑǀ⟩; a symbol abandoned by the IPA but still preferred by some linguists is ⟨ʇ̃⟩ or ⟨ᵑʇ⟩.
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.
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.
