0 (of a speech sound) made in the place between the top teeth and the highest part of the mouth -- 齿龈后音
The point of contact may be alveolar or postalveolar, and the distinctive quality may arise more from the shaping than from the position of the tongue.
An additional ' sharp ' locus subdivides coronals into anterior (dental) vs. posterior (postalveolar, palatal) sounds, at least for some whistlers.
Also, for some languages that distinguish dental vs. alveolar stops and nasals, these are actually articulated closer to prealveolar and postalveolar, respectively.
The voiced postalveolar affricative sometimes occurs as an alternative to the fricative.
However, in contrast to the "hek" which is usually used for postalveolar consonants, the "kreska" denotes alveolo-palatal consonants.
Phoneticians optionally distinguish between "prealveolar" and "postalveolar" (and likewise between "prepalatal", "midpalatal", and "postpalatal").
The dental, postalveolar and palato-velar plosives are affricated to in many contexts.
Their place of articulation is postalveolar.
