|Voiceless velar lateral affricate|
The voiceless velar lateral affricate is a relatively uncommon speech sound found as a phoneme in the Caucasus and as an allophone in several languages of eastern and southern Africa. In strict IPA, it needs to be transcribed with diacritics, but a proper letter exists in extIPA: ⟨k͜⟩.
Archi, a Northeast Caucasian language of Dagestan, has two such affricates, plain [k] and labialized [kʷ], though they are further forward than velars in most languages, and might better be called prevelar. Archi also has ejective variants of its lateral affricates, several voiceless lateral fricatives, and a voiced lateral fricative at the same place of articulation, but no alveolar lateral fricatives or affricates.
Zulu and Xhosa have a voiceless lateral affricate as an allophone of their voiceless velar affricate. Hadza has an ejective velar lateral affricate as an allophone of its velar ejective affricate. Indeed, in Hadza this [k͜ʼ] contrasts with a palatal lateral ejective affricate, [c͜ʼ]. ǁXegwi is reported to have contrasted velar /k͜/ from alveolar /t͜ɬ/.
Laghuu, a Loloish language of Vietnam, contrasts four velar lateral affricates, /k͡ʰ, k͡, ɡ͡ʟ̝, ᵑɡ͡ʟ̝/.
