The voiceless palato-alveolar fricative or domed postalveolar fricative (IPA [ʃ]) is a type of consonantal sound, used in some spoken languages.
The sound occurs in many languages and, as in English, Italian and French, where it may have simultaneous lip rounding ([ʃʷ]), although this is rarely indicated.

Features
The sound in Russian denoted by <ш> is commonly transcribed as a postalveolar fricative but is actually a laminal retroflex fricative.
