This document provides an overview of syllables, including their nature, structure in English, and principles of syllable division. It defines a syllable phonetically as consisting of an onset, nucleus, and coda. The English syllable structure is described as having optional onsets with one or more consonants and codas with up to four consonants. Principles of maximal onsets and sonority are introduced for dividing syllables between words. Examples demonstrate possible consonant combinations in onsets, codas, and ambisyllabic consonants.
