Nasal lateral click

The 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 the 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 allowed to escape through the nose, either exclusively (nasal stops) or 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]

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.

Language	Word	IPA	Meaning
Hadza	slaxxa	[ɬaᵑǁˀa] = [ɬaᵑʖˀa]	'a split'
Khoekhoe	tsoatsoaǁaposa	[tsȍàtsòȁᵑǁˀàpòsa̋] = [tsȍàtsòȁᵑʖˀàpòsa̋]	'principled'
Xhosa	inkxumo	[iᵑǁˀumo] = [iᵑʖˀumo]	'a support'
