Dental and alveolar ejectives
source · help
The alveolar ejective is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨tʼ⟩.
Features of the alveolar ejective:
- Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Since the consonant is also oral, with no nasal outlet, the airflow is blocked entirely, and the consonant is a stop.
- There are four specific variants of [tʼ]:
- Dental, which means it is articulated with either the tip or the blade of the tongue at the upper teeth, termed respectively apical and laminal.
- Denti-alveolar, which means it is articulated with the blade of the tongue at the alveolar ridge, and the tip of the tongue behind upper teeth.
- Alveolar, which means it is articulated with either the tip or the blade of the tongue at the alveolar ridge, termed respectively apical and laminal.
- Postalveolar, which means it is articulated with either the tip or the blade of the tongue behind the alveolar ridge, termed respectively apical and laminal.
- Its phonation is voiceless, which means it is produced without vibrations of the vocal cords.
- It is an oral consonant, which means air is allowed to escape through the mouth only.
- It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
