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.
Toda also has a four-way sibilant distinction, with one alveolar, one palato-alveolar, and two retroflex (apical postalveolar and subapical palatal).
They may be sub-apical retroflex and should not be confused with the more widespread postalveolar clicks, which are sometimes called retroflex.
Here the place is further back in the mouth, in the postalveolar or prepalatal region.
There are contrasting alveolar and postalveolar apical consonants, the latter often called retroflex.
There are also phonetically palatalized consonants (marked with an acute accent) that contrast with this; thus the distinction is made between palatal (postalveolar) and palatalized.
Velars are reinterpreted as palatals, labialized postalveolar affricates are reinterpreted as retroflex consonants, and other labialized consonants are removed.
