Denti-alveolar

In linguistics, a denti-alveolar consonant or dento-alveolar consonant is a consonant that is articulated with a flat tongue against the alveolar ridge and upper teeth, such as /t/ and /d/ in languages such as Spanish and French. That is, a denti-alveolar consonant is one that is alveolar and laminal.

Although denti-alveolar consonants are often labeled as "dental" because only the forward contact with the teeth is visible, the point of contact of the tongue that is farthest back is most relevant, defines the maximum acoustic space of resonance and gives a characteristic sound to a consonant.

In French, the contact that is farthest back is alveolar or sometimes slightly pre-alveolar. Spanish /t/ and /d/ are laminal denti-alveolar, and /l/ and /n/ are alveolar but assimilate to a following /t/ or /d/. Similarly, Italian /t/, /d/, /t͡s/, /d͡z/ are denti-alveolar, and /l/ and /n/ are alveolar.

The dental clicks are also laminal denti-alveolar.
