Speakers naturally chunk words into beats. A syllable is a unit of pronunciation typically organized around a vowel or vowel-like nucleus, optionally preceded by consonants in an onset and followed by consonants in a coda.

Syllable structure constraints determine legal sound sequences in a language. Some languages favor simple consonant-vowel syllables; others allow complex clusters. Stress, timing, and poetic meter operate on syllabic units.

Children show early sensitivity to syllables in language play and early writing. Phonologists debate universal syllable templates versus language-specific organizations. Practical applications include hyphenation, pronunciation teaching, and speech synthesis.
