Features
Features of a voiceless retroflex lateral 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 retroflex, which prototypically means it is articulated subapical (with the tip of the tongue curled up), but more generally, it means that it is postalveolar without being palatalized. That is, besides the prototypical subapical articulation, the tongue can be apical (pointed) or, in some fricatives, laminal (flat).
- 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 lateral consonant, which means it is produced by directing the airstream over the sides of the tongue, rather than down the middle.
- Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most sounds.
