The voiceless velar lateral fricative is a rare speech sound. As one element of an affricate, it is found for example in Zulu and Xhosa (see velar lateral ejective affricate). 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 [ʟ̝̊], labialized [ʟ̝̊ʷ], fortis [ʟ̝̊ː], and labialized fortis [ʟ̝̊ːʷ]. 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.[1]

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 (Ⱡ, ⱡ). This sound also appears in syllable coda position as an allophone of the voiced velar lateral fricative in Kuman.[2]

The IPA has no separate symbol for these sounds, but they can be transcribed as a devoiced raised velar lateral approximant, ⟨ʟ̝̊⟩ (here the devoicing ring diacritic is placed above the letter to avoid clashing with the raising diacritic). By analogy with existing IPA laterals, a small capital Ɬ (⟨𝼄⟩) is used in the extIPA:

𝼄⟩ was added to Unicode in 2021.

Some scholars also posit the voiceless velar lateral approximant distinct from the fricative. The approximant may be represented in the IPA as ⟨ʟ̥⟩.
