A syllable is a unit of sound composed of
a central peak of sonority (usually a vowel), and
the consonants that cluster around this central peak.
Syllable structure, which is the combination of allowable segments and typical sound sequences, is language specific.
Initial segment of a syllable
Core of a syllable, consisting of a nucleus and coda (see below)
Central segment of a syllable
Closing segment of a syllable
