Close back rounded vowel to Voiceless labiodental fricative

The transformation of the close back rounded vowel /u/ into the voiceless labiodental fricative /f/ is a rare but attested phonetic shift, primarily observed as a form of high vowel fricativization. This change involves the vowel losing its vocalic quality and acquiring a fricative manner of articulation, while retaining a labial feature.
