Voiceless velar lateral fricative
The voiceless velar lateral fricative is a very rare speech sound. As one element of an affricate, it is found for example in Zulu and Xhosa. However, a simple fricative has only been reported from a few languages in the Caucasus and New Guinea.
Archi, a Northeast Caucasian language of Dagestan, has four voiceless velar lateral fricatives: plain, labialized, fortis, and labialized fortis. Although clearly fricatives, these are further forward than velars in most languages, and might better be called prevelar. Archi also has a voiced fricative, as well as a voiceless and several ejective lateral velar affricates, but no alveolar lateral fricatives or affricates.
In New Guinea, some of the Chimbu–Wahgi languages such as Melpa, Middle Wahgi, and Nii, have a voiceless velar lateral fricative, which they write with a double-bar el. This sound also appears in syllable coda position as an allophone of the voiced velar lateral fricative in Kuman.
The IPA has no separate symbol for these sounds, but they can be transcribed as a devoiced raised velar lateral approximant, . By analogy with existing IPA laterals, a small capital Ɬ is used in the extIPA:
SIL International has added these symbols to the Private Use Areas of their Gentium, Charis and Doulos fonts, at U+F268.Features
