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 [𝼄], labialized [𝼄ʷ], fortis [𝼄ː], and labialized fortis [𝼄ːʷ]. 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 (, ). This sound also appears in syllable coda position as an allophone of the voiced velar lateral fricative in Kuman.[2]

The extIPA has the letter ⟨𝼄⟩ for this sound. It was added to Unicode in 2021.

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

Features

[edit]

Features of the voiceless velar lateral fricative:

  • Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence.
  • Its place of articulation is velar, which means it is articulated with the back of the tongue (the dorsum) at the soft palate.
  • Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
  • It is an oral consonant, which means air is allowed to escape through the mouth only.
  • It is a lateral consonant, which means it is produced by directing the airstream over the sides of the tongue, rather than down the middle.
  • Its airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.
