Voiceless velar fricative to Voiceless alveolo-palatal fricative

The voiceless velar fricative [x] fronts to the voiceless alveolo-palatal fricative [ɕ] before high front vowels and glides — a palatalization that shifts the place of articulation forward from the velum. The defining case is Standard Mandarin, where the whole velar series /k kʰ x/ was drawn forward to /tɕ tɕʰ ɕ/ before /i/ and /y/.

Language Examples

Mandarin Chinese Sino-Tibetan

曉 *[x]→[ɕ]— Over the last two to three centuries the velar initials palatalized before [i] and [y], merging with the dental sibilants into the [tɕ tɕʰ ɕ] series now spelled ⟨j q x⟩ in Pinyin. The same 曉 initial stays [x] before back vowels — 海 hǎi [xai] 'sea' — but fronts to [ɕ] before a front vowel: 希 xī [ɕi] 'hope'.
