Close back rounded vowel to Voiceless velar fricative
The shift from the high back rounded vowel [u] to the voiceless velar fricative [x] is a form of consonantalization or triggered affrication, typically observed in loanword adaptations or as a sub-phonemic coarticulatory effect.

Language Examples
two [tʰu]→[t͡xu]— Sub-phonemic affrication where the backness of [u] triggers a velar fricative release of the preceding stop.
Loanword Adaptation Various
[u/w]→[x]— Strengthening of the labial/back glide into a velar fricative in languages lacking the glide (e.g., adaptation of 'w' as 'kh' or 'x').
