Voiceless palatal lateral approximant

The voiceless palatal lateral approximant is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ʎ̥ (devoiced ʎ), and the equivalent X-SAMPA symbol is L_0.

IPA Number157 402A

If distinction is necessary, the voiceless alveolo-palatal lateral approximant may be transcribed as l̠̊ʲ or l̥˗ʲ (both symbols denote a devoiced, retracted and palatalized l) or ʎ̥˖ (devoiced and advanced ʎ); these are essentially equivalent, since the contact includes both the blade and body (but not the tip) of the tongue. The equivalent X-SAMPA symbols are l_0_-' or l_0_-_j and L_0_+, respectively. A non-IPA letter ȴ̊ (devoiced ȴ, which is an ordinary "l", plus the curl found in the symbols for alveolo-palatal sibilant fricatives ɕ, ʑ) can also be used.

It is found as a phoneme distinct from the voiced /ʎ/ in the Xumi language spoken in China.[1][2]


Features of the voiceless palatal lateral approximant:

  • 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.

  8. An example of a scholar disagreeing with this position is Scholtz (2009). On page 15, she provides a phoneme chart for Trøndersk, in which /ʎ/ is included. Under the phoneme chart she writes "Vanvik also lists /ʎ̥/ as an underlying phoneme, but that’s ridiculous." She provides no further explanation for that.
