The voiced velar fricative (), has undergone a sound change in Turkish by which the consonant was completely lost and compensatory lengthening of the preceding vowel occurred. Even though the sound has been completely lost in standard Turkish, the sound change is not yet complete in some Turkish dialects and the corresponding velar fricative found in cognate words in the closely related Azerbaijani language and the Turkish-influenced Crimean Tatar language. The previous consonantal nature of the sound is evinced by earlier English loanwords from Turkish, such as yogurt/yoghurt (modern Turkish yoğurt, ) and agha (modern Turkish ağa, ).
