Dental and alveolar ejective stops

Consonantal sounds represented by ⟨tʼ⟩ in IPA

The alveolar and dental ejective stops are types of 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reversed apostrophe is sometimes used to represent light aspiration, as in Armenian linguistics ⟨p‘ t‘ k‘⟩; this usage is obsolete in the IPA.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.
