A syllable is a word or part of a word that can be pronounced with one impulse from the voice. A syllable always contains a vowel sound, and most syllables have consonants associated with the vowel.
In English, some syllables in words or sentences are stressed with more force from the voice than others. Those stressed syllables are called accented syllables.
Examples of words divided into syllables:
