Coronal consonant

Only the front of the tongue (coronal) has such dexterity among the major places of articulation, allowing such variety of distinctions.

Coronals have another dimension, grooved, to make sibilants in combination with the orientations above.

In Arabic and Maltese philology, the sun letters represent coronal consonants.

In Australian Aboriginal languages, coronals contrast with peripheral consonants.

Shaded areas denote articulations judged impossible.
