In linguistics, a denti-alveolar consonant is a consonant that is articulated with a flat tongue against the alveolar ridge and upper teeth, such as and (but not or ) 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, it is the rear-most point of contact of the tongue that is most relevant, for this is what defines the maximum acoustic space of resonance and will give a consonant its characteristic sound.
In the case of French, the rear-most contact is alveolar or sometimes slightly pre-alveolar. Spanish and are laminal denti-alveolar, while and are alveolar (though they assimilate to a following or ). Similarly, Italian , , , are denti-alveolar, while and are alveolar.
The dental clicks are also laminal dental or alveolar.
