Tenuis retroflex click

The voiceless or more precisely tenuis retroflex click is a rare click consonant. In practical orthography, an ad hoc symbol ⟨‼⟩ is used for the retroflex clicks; a tenuis click with a velar rear articulation is ⟨k͡‼⟩ or ⟨k͜‼⟩, commonly abbreviated to ⟨k‼⟩, ⟨ᵏ‼⟩ or just ⟨‼⟩. The implicit symbol in the International Phonetic Alphabet is ⟨k͡𝼊⟩ or ⟨k͜𝼊⟩, abbreviated ⟨k𝼊⟩, ⟨ᵏ𝼊⟩ or just ⟨𝼊⟩. Linguists who prefer the old IPA letters use the analogous Doke convention of ⟨k͡ψ⟩ or ⟨k͜ψ⟩, abbreviated ⟨kψ⟩, ⟨ᵏψ⟩ or ⟨ψ⟩. For a click with a uvular rear articulation, the equivalents are ⟨q͡‼, q͜‼, q‼, 𐞥‼⟩, ⟨q͡𝼊, q͜𝼊, q𝼊, 𐞥𝼊⟩ and ⟨q͡ψ, q͜ψ, qψ, 𐞥ψ⟩. Sometimes the accompanying letter comes after the click letter, e.g. ⟨𝼊k⟩ or ⟨𝼊ᵏ⟩; this may be a simple orthographic choice, or it may imply a difference in the relative timing of the releases.
