Voiced velar plosive to Voiced labio-velar approximant

The shift from the voiced velar stop [ɡ] to the voiced labio-velar approximant [w] is a process of lenition and vocalization. This transformation typically involves the weakening of the velar closure into a fricative [ɣ] before fully vocalizing into a glide, often encouraged by neighboring back vowels.
