Palatal nasal click

The palatal 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 ⟨ǂ̃⟩ or ⟨ᵑǂ⟩. (Variations of the latter include ⟨ŋǂ⟩ and ⟨ǂŋ⟩.)

Features

Features of the palatal 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 palatal, which means it is articulated with the middle or back part of the tongue raised to the hard palate.

• 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

Palatal nasal clicks are only found in the various Khoisan languages families of southern Africa and in the neighboring Yeyi language.

Glottalized palatal nasal 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.
