We have often seen comments on words that have all five vowels AEIOU, usually in alphabetic order. I decided to take a particular dictionary and list all the words I could find with AEIOU in any order, eliminating those words in which a vowel was repeated. The dictionary I selected was the Funk & Wagnalls Standard College Dictionary (1973 printing) which I use frequently in the game of Scrabble.
"An AEIOU Examination,"
Word Ways: Vol. 12
, Article 19.
