The word ANEMONE has only seven letters, but four syllables; this gives $1.75$ letters per syllable on average.
Can you find another English word with
that is not a proper name
that has at least four syllables
that has an average number of letters per syllable below $1.75$
(If there are different solutions with the same average then the one with more consonants gets the prize. If $y$ is pronounced as vowel it counts as a vowel. Otherwise I count $y$ as a consonant.)
W
with a score of $0.\overline{33}$ although it's questionable if that counts as a word. $\endgroup$
