A labial–coronal consonant is a
consonant
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract. Examples are and pronounced with the lips; and pronounced with the front of the tongue; and pronounced wit ...
produced with two simultaneous
articulators: With the lips ('labial'; a , , or sound), and with the tongue (at the gums, an 'alveolar' , , or sound, or further back, a 'post-alveolar' , sound).
Several languages have been claimed to have such sounds, such as
Margi and
Bura in Nigeria. However, most researchers interpret them as having sequences of labial and coronal consonants, a rather common occurrence in Africa. The
