Coronal consonants are consonants articulated with the flexible front part of the tongue. Only the coronal consonants can be divided into apical (using the tip of the tongue), laminal (using the blade of the tongue), domed (with the tongue bunched up), or subapical (using the underside of the tongue), as well as a few rarer orientations, because only the front of the tongue has such dexterity. Coronals have another dimension, grooved, that is used to make sibilants in combination with the orientations above.
