# 2.3.1. 构成（Structure of a syllable）
|
||
|
||
**英文的词汇由至少一个音节构成**。英文中出现频率最高的几个词，*a/an*, *the*, *of*, *to*, *for*... 等等都是单音节词汇。有的词汇可能很长，由很多音节构成。在英文词典中能找到的最长词汇总计由 19 个音节，45 个字母构成：

|
||
> `/ˌnumənəʊˌəltrəˌmaɪkrəˌskɑpɪkˌsɪləkəʊvɑlˌkeɪnəʊˌkəʊniˈəʊsəs/`
|
||
|
||
一个音节中，有且只有一个元音（被称为 *nucleus*），也是该音节的韵（*rhyme*）。音节以元音为核心，前后可有多达三个辅音构成的组合。
|
||
|
||
In a syllable, there is *only* one vowel, known as the *nucleus*, which forms the *rhyme* of the syllable. This vowel is at the core of the syllable, and it can be surrounded by up to three consonants.
