音节

这是所有语言共同的特性：

Here are some universal features of all languages around the world:

• 自然语音都以音节为最基础单位。
• The basic unit of all natural speech is the syllable.
• 音节以元音为核心。
• Every syllable is centered around a vowel.
• 每个音节有且只有一个元音。
• Each syllable has and only has one vowel.

元音之于音节，正如细胞核之于细胞。

A vowel is to a syllyble, just as a nucleus to a cell.
