Orbicular consonant



Orbiculars or frenulars are consonants articulated in the space between the back of the upper lip and the upper front teeth. The word orbicular comes from the orbicularis oris muscle, also known as the "kissing muscle".

Occurrence
Suqi, a member of the project, has proposed transcribing orbiculars by adding the non-standard IPA diacritic ⟨◌̫⟩ to the corresponding alveolar and labial consonants, for example: abne [ad̫n̫ɛ].

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.
