Nasal lateral click
Consonantal sound
From Wikipedia, the free encyclopedia
A lateral nasal click is a click consonant found primarily among the languages of southern Africa. The symbol in the International Phonetic Alphabet for a nasal lateral click with a velar rear articulation is ⟨ŋ͡ǁ⟩ or ⟨ŋ͜ǁ⟩, commonly abbreviated to ⟨ŋǁ⟩, ⟨ᵑǁ⟩ or ⟨ǁ̃⟩; a symbol abandoned by the IPA but still preferred by some linguists is ⟨ŋ͡ʖ⟩ or ⟨ŋ͜ʖ⟩, abbreviated ⟨ŋʖ⟩, ⟨ᵑʖ⟩ or ⟨ʖ̃⟩. For a click with a uvular rear articulation, the equivalents are ⟨ɴ͡ǁ, ɴ͜ǁ, ɴǁ, ᶰǁ⟩ and ⟨ɴ͡ʖ, ɴ͜ʖ, ɴʖ, ᶰʖ⟩. Sometimes the accompanying letter comes after the click letter, e.g. ⟨ǁŋ⟩ or ⟨ǁᵑ⟩; this may be a simple orthographic choice, or it may imply a difference in the relative timing of the releases.[1]

Features
Features of a lateral 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 phonation is voiced, which means the vocal cords vibrate during the articulation.
- It is a nasal consonant, which means air is exclusively allowed to escape through the nose for nasal stops; otherwise, in addition to through the mouth.
- It is a lateral consonant, which means it is produced by directing the airstream over the sides of the tongue, rather than down the middle.
Occurrence
Lateral nasal clicks are found primarily in the various Khoisan language families of southern Africa and in some neighboring Bantu languages.[2][3]
