Voiced postalveolar fricative to Voiceless velar fricative
The transformation from the voiced postalveolar fricative /ʒ/ to the voiceless velar fricative /x/ is a notable historical sound change, particularly attested in the development of Castilian Spanish. This shift involves both a loss of voicing and a significant retraction of the place of articulation.

Language Examples
/ʒ/→/x/— In Old Spanish, the voiced postalveolar fricative /ʒ/ (represented by 'j' or 'g' before 'e', 'i') underwent devoicing to /ʃ/ and subsequently retracted to /x/ (the modern 'jota') around the mid-16th century.
México (historical pronunciation)→México (modern pronunciation)— The 'x' in place names like 'México' historically represented /ʃ/, which later shifted to /x/ in Castilian Spanish.
