Features
Features of an alveolo-palatal 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 alveolo-palatal. This means that:
- The articulation is postalveolar and laminal, meaning that the tongue blade contacts the roof of the mouth in the area behind the alveolar ridge (the gum line). Some phoneticians instead argue that the articulation is pre-palatal and dorsal, meaning that the back of the tongue (the dorsum) is raised toward the front of the hard palate.
- It is heavily palatalized, meaning that the middle of the tongue is bowed and raised towards the hard palate.
- Its phonation is voiceless, 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.
