Alveolaarsetes

Alveolaarsetes refers to sounds produced with the tip or blade of the tongue against the alveolar ridge. The alveolar ridge is the small, hard bump located just behind the upper front teeth. This point of articulation is common in many languages.

In phonetics, alveolar sounds can be classified by their manner of articulation. Plosives, such as the 't' and 'd' sounds in English, involve a complete closure of the airway at the alveolar ridge, followed by a sudden release of air. Fricatives, like the 's' and 'z' sounds, are produced by forcing air through a narrow gap at the alveolar ridge, creating friction. Nasals, such as the 'n' sound, involve air passing through the nasal cavity while the tongue is at the alveolar ridge. Approximants, like the 'l' sound, are articulated with less constriction, allowing air to flow more freely.

The precise placement and contact with the alveolar ridge can vary slightly between individuals and languages, leading to subtle phonetic differences. However, the general principle of using this part of the mouth for articulation defines the category of alveolar sounds. Many of the most common consonants in human languages are alveolar.
