Voiceless velar fricative to Voiced labio-velar approximant

The transformation from a voiceless velar fricative [x] to a voiced labio-velar approximant [w] is a multi-stage lenition process. It typically involves an initial voicing of the velar fricative, followed by a further weakening (approximantization) and labialization, often in the context of surrounding rounded vowels.

Language Examples

[x]→[w]— In Old English, the voiceless velar fricative [x] could be voiced to [ɣ] in intervocalic or other voiced environments. This voiced velar fricative [ɣ] subsequently vocalized to a labio-velar approximant [w] in Middle English, particularly after back vowels. For instance, Old English 'fugol' [ˈfuɣol] evolved to Middle English 'fowl' [faʊl], where the [ɣ] became [w].
