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 (Ⱡ, ⱡ). 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
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.
- The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.

Approximants are speech sounds that involve the articulators approaching each other but not narrowly enough nor with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no turbulence. This class is composed of sounds like and semivowels like and, as well as lateral approximants like.
A lateral is a consonant in which the airstream proceeds along one or both of the sides of the tongue, but it is blocked by the tongue from going through the middle of the mouth. An example of a lateral consonant is the English L, as in Larry. Lateral consonants contrast with central consonants, in which the airstream flows through the center of the mouth.
Velars are consonants articulated with the back part of the tongue against the soft palate, the back part of the roof of the mouth.
In phonetics, ejective consonants are usually voiceless consonants that are pronounced with a glottalic egressive airstream. In the phonology of a particular language, ejectives may contrast with aspirated, voiced and tenuis consonants. Some languages have glottalized sonorants with creaky voice that pattern with ejectives phonologically, and other languages have ejectives that pattern with implosives, which has led to phonologists positing a phonological class of glottalic consonants, which includes ejectives.
The voiced velar lateral approximant is a type of consonantal sound, used as a distinct consonant in a very small number of spoken languages in the world. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʟ⟩ a small capital version of the Latin letter l, and the equivalent X-SAMPA symbol is L\.
The voiced alveolar lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents voiced dental, alveolar, and postalveolar lateral fricatives is ⟨ɮ⟩, and the equivalent X-SAMPA symbol is K\.
The voiced velar approximant is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɰ⟩, and the equivalent X-SAMPA symbol is M\.
The voiced uvular fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʁ⟩, an inverted small uppercase letter ⟨ʀ⟩, or in broad transcription ⟨r⟩ if rhotic. This consonant is one of the several collectively called guttural R when found in European languages.
The voiceless labial–velar fricative is a type of consonantal sound, used in spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʍ⟩. This was defined as a voiceless until 1979, when it was defined as a fricative with the place of articulation of the same way that is an approximant with the place of articulation of.
The voiceless palatal fricative is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ç⟩, and the equivalent X-SAMPA symbol is C. It is the non-sibilant equivalent of the voiceless alveolo-palatal fricative.
The voiceless palatal plosive or stop is a type of consonantal sound used in some vocal languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨c⟩, and the equivalent X-SAMPA symbol is c.
The voiceless palatal lateral fricative is a type of consonantal sound, used in a few spoken languages.
Doubly articulated consonants are consonants with two simultaneous primary places of articulation of the same manner. They are a subset of co-articulated consonants. They are to be distinguished from co-articulated consonants with secondary articulation; that is, a second articulation not of the same manner. An example of a doubly articulated consonant is the voiceless labial-velar plosive, which is a and a pronounced simultaneously. On the other hand, the voiceless labialized velar plosive has only a single stop articulation, velar, with a simultaneous approximant-like rounding of the lips. In some dialects of Arabic, the voiceless velar fricative has a simultaneous uvular trill, but this is not considered double articulation either.
The voiceless palatal affricate is a type of consonantal sound, used in some spoken languages. The symbols in the International Phonetic Alphabet that represent this sound are ⟨c͡ç⟩ and ⟨c͜ç⟩, and the equivalent X-SAMPA symbol is c_C. The tie bar may be omitted, yielding ⟨cç⟩ in the IPA and cC in X-SAMPA.
The voiced velar lateral fricative is a very rare consonantal sound that can be found in Archi, a Northeast Caucasian language of Dagestan, in which it is clearly a fricative, although further forward than velars in most languages, and might better be called prevelar.
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: ⟨k͜𝼄⟩.
The velar lateral ejective affricate is a rare type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨k𝼄ʼ⟩.
Ejective-contour clicks, also called sequential linguo-glottalic consonants, are consonants that transition from a click to an ejective sound, or more precisely, have an audible delay between the front and rear release of the click. All click types have linguo-glottalic variants, which occur as both stops and affricates, and may be voiced. At least a voiceless linguo-glottalic affricate is attested from all Khoisan languages of southern Africa, as well as from the Bantu language Yeyi from the same area, but they are unattested elsewhere.
The voiceless labial–palatal fricative or approximant is a type of consonantal sound, used in a few spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɥ̊⟩ or ⟨ɸ͡ç⟩. The former – more accurately the voiceless labialized palatal fricative by those who consider it to be a fricative – is the voiceless counterpart of the voiced labial–palatal approximant. Other linguists posit voiceless approximants distinct from voiceless fricatives; to them, is a voiceless labialized palatal approximant.
