In phonetics, alveolo-palatal (or alveopalatal) consonants are palatalized postalveolar fricatives, articulated with the blade of the tongue behind the alveolar ridge, and the body of the tongue raised toward the palate. They are similar to palato-alveolar and retroflex fricatives, but are laminal rather than apical or sub-apical as the retroflex fricatives are, and are more fully palatalized than the "domed" palato-alveolar fricatives are. Alveolo-palatal sibilants can be found in Chinese languages such as Mandarin, Hakka, and Wu, as well as Abkhaz, Polish, Russian, Ubykh, Japanese, Korean, and Serbian.
