Features

Features of the alveolar ejective fricative:

• Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence.
• Its place of articulation is alveolar which means it is articulated with the tip of the tongue against the alveolar ridge.
• 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 out of the glottis, rather than from the lungs.
