Voiceless palatal lateral approximant

Voiceless palatal lateral approximant
ʎ̥
IPA number	157 402A
Encoding
X-SAMPA	L_0

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.

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

Features of the voiceless palatal lateral approximant:

• Its manner of articulation is approximant, which means it is produced by narrowing the vocal tract at the place of articulation, but not enough to produce a turbulent airstream.

• Its place of articulation is palatal, which means it is articulated with the middle or back part of the tongue raised to the hard 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 lungs and diaphragm, as in most sounds.

Occurrence

	Some subdialects of Trøndersk[4]	tatle	[tɑʎ̥]	'acting silly'	According to some scholars,[5][6] it is a phoneme that contrasts with /ʎ/ (as in /tɑʎ/ 'softwood'.)[4] See Norwegian phonology

Under the phoneme chart she writes "Vanvik also lists /ʎ̥/ as an underlying phoneme, but that’s ridiculous :)." She provides no further explanation as to why it is ridiculous.
