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 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: moplá [n̫ot̫l̫ɜ].

Languages with orbicular consonants are mainly concentrated in the Fechara region.
