Diphthong au to Voiced labiodental fricative

The diphthong [au] can undergo a phonetic transformation where its second vocalic element, the close back rounded vowel [u], strengthens into a voiced labiodental fricative [v]. This process, known as consonantization and fricativization, results in a consonantal outcome for the latter part of the original diphthong.

Consonantization of the Vocalic Glide, Fricativization, Diphthong Reduction

Language Examples

αυ→[av]— The Ancient Greek diphthong /au̯/ evolved to /av/ in Modern Greek when followed by a voiced consonant or a vowel. For example, Ancient Greek αὐλός (aulós) is pronounced /avˈlos/ in Modern Greek.
