Linguolabials or apicolabials are consonants
articulated by placing the tongue tip or blade against the
upper lip, which is drawn downward to meet the tongue. They
represent one extreme of a coronal articulatory continuum
which extends from linguolabial to sub-apical
palatal places of articulation. Cross-linguistically,
linguolabial consonants are very rare, though they do not
represent a particularly exotic combination of articulatory
configurations, unlike click
consonants or ejectives.
They are found in a cluster of languages in Vanuatu,
as well as in Umotina,
a recently extinct Bororoan
language of Brazil,
and as extraphonotactic
sounds worldwide.
The
linguolabial consonants are transcribed in the International
Phonetic Alphabet by adding the "seagull" diacritic
to the corresponding alveolar
consonant. They are sometimes seen with the letter for
a bilabial consonant instead, but this usage is not recognized
by the International
Phonetic Association, and would imply that both lips
are used.
