Dental and alveolar ejective stops

Alveolar and dental ejective stops are consonantal sounds, usually described as voiceless, that are pronounced with a glottalic egressive airstream. In the International Phonetic Alphabet, ejectives are indicated with a "modifier letter apostrophe" ⟨ʼ⟩, as in this article. A reversed apostrophe is sometimes used to represent light aspiration, as in Armenian linguistics ⟨p‘ t‘ k‘⟩; this usage is obsolete in the IPA. In other transcription traditions, the apostrophe represents palatalization: ⟨pʼ⟩ = IPA ⟨pʲ⟩. In some Americanist traditions, an apostrophe indicates weak ejection and an exclamation mark strong ejection: ⟨k̓ , k!⟩. In the IPA, the distinction might be written ⟨kʼ, kʼʼ⟩, but it seems that no language distinguishes degrees of ejection.

In alphabets using the Latin script, an IPA-like apostrophe for ejective consonants is common. However, there are other conventions. In Hausa, the hooked letter ƙ is used for /kʼ/. In Zulu and Xhosa, whose ejection is variable between speakers, plain consonant letters are used: p t k ts tsh kr for /pʼ tʼ kʼ tsʼ tʃʼ kxʼ/. In some conventions for Haida and Hadza, double letters are used: tt kk qq ttl tts for /tʼ kʼ qʼ tɬʼ tsʼ/ (Haida) and zz jj dl gg for /tsʼ tʃʼ cʎ̥˔ʼ kxʼ/ (Hadza).

In Oromo, /tʼ/ is written ⟨x⟩.

Features

Features of an alveolar ejective stop:

• 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 plosive.
• 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 un-voiced, which means it is produced without vibrations of the vocal cords.
• It is an oral consonant, which means that air is not allowed to escape through the nose.
• It is a median consonant, which means it is produced by directing the airstream down the midline of the tongue, rather than to the sides.
• The airstream mechanism is ejective (glottalic egressive), which means the air is forced out by pumping the glottis upward.
