Voiced alveolar click

The voiced (post)alveolar click is a click consonant found primarily among the languages of southern Africa. The symbol in the International Phonetic Alphabet for a voiced alveolar click with a velar rear articulation is ⟨ɡ͡ǃ⟩ or ⟨ɡ͜ǃ⟩, commonly abbreviated to ⟨ɡǃ⟩, ⟨ᶢǃ⟩ or ⟨ǃ̬⟩; a symbol abandoned by the IPA but still preferred by some linguists is ⟨ɡ͡ʗ⟩ or ⟨ɡ͜ʗ⟩, abbreviated ⟨ɡʗ⟩, ⟨ᶢʗ⟩ or ⟨ʗ̬⟩. For a click with a uvular rear articulation, the equivalents are ⟨ɢ͡ǃ, ɢ͜ǃ, ɢǃ, 𐞒ǃ⟩ and ⟨ɢ͡ʗ, ɢ͜ʗ, ɢʗ, 𐞒ʗ⟩. Sometimes the accompanying letter comes after the click letter, e.g. ⟨ǃɡ⟩ or ⟨ǃᶢ⟩; this may be a simple orthographic choice, or it may imply a difference in the relative timing of the releases.

In languages which use the Bantu letters for clicks, this is most commonly written $⟨J!⟩$, but it is written $⟨gq⟩$ in those languages that use $⟨dq⟩$ for the uvular fricative.
