What English words contain the five vowel letters, a, e, i, o, and u, with fewest consonant letters?
Facetious and abstemious contain the five in alphabetical order, and each contains four consonant letters: fcts in facetious, and bstm in abstemious. There are two instances of s in the case of abstemious, but we are counting each letter once, so both words achieve a consonant score of four.
We are looking for the word or words that contain all five of these vowel letters, not necessarily in alphabetical order, and perhaps repeated, and that have the lowest consonant score.
(Note: please can nobody edit to change "vowel letter" and "consonant letter" to "vowel" and "consonant". "Vowels" and "consonants" are sounds - they are classes of phonemes, not classes of written letters. Often a vowel letter does not represent a vowel. I am also aware that y often does represent a vowel and that w sometimes does.)
