The voiceless or more precisely tenuis bilabial click is a click consonant found in some languages of southern Africa.
The symbol in the International Phonetic Alphabet for a tenuis bilabial click with a velar rear articulation is ⟨k͡ʘ⟩ or ⟨k͜ʘ⟩, commonly abbreviated to ⟨kʘ⟩, ⟨ᵏʘ⟩ or just ⟨ʘ⟩. For a click with a uvular rear articulation, the equivalents are ⟨q͡ʘ, q͜ʘ, qʘ, ʘ⟩.
Sometimes the accompanying letter comes after the click letter, e.g. ⟨ʘk⟩ or ⟨ʘᵏ⟩; this may be a simple orthographic choice, or it may imply a difference in the relative timing of the releases.
The airstream mechanism is lingual ingressive (also known as velaric ingressive), which means a pocket of air trapped between two closures is rarefied by a "sucking" action of the tongue, rather than being moved by the glottis or the lungs/diaphragm. The release of the forward closure produces the "click" sound. Voiced and nasal clicks have a simultaneous pulmonic egressive airstream.
