Orbicular consonant



Orbiculars are consonants articulated in the space between the back of the upper lip and the upper front teeth. They can be divided into linguoorbilculars (articulated by placing the toungue against the labial frenulum, found in languages of Pewo) and labioorbilculars (articulated with the bottom lip against the frenulum). The word orbicular is derived from the orbicularis oris muscle.

Occurrence
Orbiculars arose from Proto-North-Socoan linguolabial consonants in the Fecharic languages. They occur in the neighbouring languages in Fechara—which borrowed them, from Fecharese.
