Features

Features of a palato-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 either the tip or the blade of the tongue at the alveolar ridge, termed respectively apical and laminal.
• Its phonation is un-voiced, which means it is produced without vibrations of the vocal cords.
• It is an oral consonant, which means that air is not allowed to escape through the nose.
• It is a median consonant, which means it is produced by directing the airstream down the midline of the tongue, rather than to the sides.
• The airstream mechanism is ejective (glottalic egressive), which means the air is forced out by pumping the glottis upward.
