What Are Six Syllable Words?
A six syllable word is spoken as six syllables, such as re-spon-si-bil-i-ty and i-den-ti-fi-ca-tion. Each syllable holds one vowel sound. Six syllable words are rare, since English rarely stacks six vowel sounds into one word without breaking it into a compound or a phrase.
Syllable count follows vowel sounds, not letters. Reliability has eleven letters and six syllables, while strength has eight letters and one. To check any word, say it aloud with a hand under the chin and count how many times the jaw drops.
