Features of the alveolar ejective fricative:

★ Its manner of articulation is sibilant fricative, which means it is produced by directing air flow through a groove in the tongue at the place of articulation and directing it over the sharp edge of the teeth, causing high-frequency turbulence.

★ Its place of articulation is alveolar, which means it is articulated with either the tip or the blade of the tongue against the alveolar ridge, termed respectively ''apical'' and ''laminal''.

★ Its phonation type is voiceless, which means it is produced without vibrations of the vocal cords.

★ It is an oral consonant, which means air is allowed to escape through the mouth.

★ It is a central consonant, which means it is produced by allowing the airstream to flow over the center of the tongue, rather than the sides.

★ The airstream mechanism is glottalic egressive, which means it is produced by pushing air with the glottis, rather than with the diaphragm.
