This document discusses the structure of the English syllable. It defines a syllable as consisting of a center with less obstruction to airflow, known as the nucleus, surrounded by optional onset and coda elements with greater obstruction. The minimum syllable contains just a vowel nucleus, while other syllables may include up to three consonants in the onset before the vowel and up to four consonants in the coda after the vowel. In some cases, a consonant such as /l/, /r/, or nasal can act as the syllabic nucleus instead of a vowel.
