Voiceless dentolabial fricative

The voiceless dentolabial fricative is a type of consonantal sound used in some dialects of Greenlandic.

Whereas a typical voiceless labiodental fricative [f] is articulated with the upper teeth contacting the lower lip, a voiceless dentolabial fricative [f͆] is articulated in the opposite direction, with the lower teeth contacting the upper lip. While the International Phonetic Alphabet has no symbol to transcribe this distinction, the extIPA uses the diacritic ⟨◌͆⟩, the above variant of the traditional IPA symbol for dentalization ⟨◌̪⟩, to indicate dentolabial articulation in the context of labial consonants. This sound can therefore be transcribed with the symbol ⟨f͆⟩, as is used in the context of this article.
