Voiceless velar fricative to Voiced uvular fricative

Language Examples

Georgian (Kartvelian) Kartvelian

ხ [x] (velar)→[χ] (uvular, dialectal)— Georgian ხ is standardly [x] (voiceless velar fricative), but in some eastern dialects and in connected speech before back vowels it is realized as uvular [χ]. Georgian also has a separate uvular stop series (ყ [q']).

Dutch (Northern Standard) Germanic

[x]→[χ]— Widespread shift where the historical velar 'hard G' is realized as a uvular fricative in standard and northern dialects.

Modern Greek Hellenic

[x]→[χ]— Allophonic and dialectal variation where the velar fricative (from historical Chi) is realized as uvular before back vowels.
