點解叫人安靜要"殊"?

The sound "sh" (IPA [ʃ]) occurs as an interjection, meaning "quiet!", in many languages, including English, Hebrew , Polish.

In Hebrew, it happens to be the first sound of the word 'sheket' meaning 'quiet!'.
起源自英語, 希伯來文 及 波蘭語.
The Swedish linguist and comedian Fredrik Lindström claims, in his book Jordens smartaste ord, that the interjection is found with the same meaning in nearly all of the world's languages.
久而久之, 在歐洲語系中流傳下去,直到今日.

如果哇哇聲咁叫人安靜咪仲嘈
殊殊聲細聲d嘛
