The voiceless or more precisely tenuis palatal click is a click consonant found primarily among the languages of southern Africa.
The symbol in the International Phonetic Alphabet for a tenuis palatal click with a velar rear articulation is ⟨k͡ǂ⟩ or ⟨k͜ǂ⟩, commonly abbreviated to ⟨kǂ⟩, ⟨ᵏǂ⟩ or simply ⟨ǂ⟩. Linguists who prefer the old IPA letters use the analogous Beach convention[2] of ⟨k͡𝼋⟩ or ⟨k͜𝼋⟩, abbreviated ⟨k𝼋⟩, ⟨ᵏ𝼋⟩ or just ⟨𝼋⟩. For a click with a uvular rear articulation, the equivalents are ⟨q͡ǂ, q͜ǂ, qǂ, 𐞥ǂ⟩ and ⟨q͡𝼋, q͜𝼋, q𝼋, 𐞥𝼋⟩.
Sometimes the accompanying letter comes after the click letter, e.g. ⟨ǂk⟩ or ⟨ǂᵏ⟩; this may be a simple orthographic choice, or may imply a difference in the relative timing of the releases.[3]
^Kirshenbaum assigns ⟨c!⟩ indifferently to both palatal and alveolar clicks.
