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 air is allowed to escape through the mouth only.
It is a
central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
