What is the shortest word that has all of the vowels in it?

SEQUOIA - (noun) a gigantic evergreen tree of the western United States.

The word is derived from the Cherokee man Sequoia, who created the Cherokee alphabet, consisting of 85 characters. He is said to be the only person ever to create a written language, without being literate in any language himself. He saw Whites reading and writing and proceeded to create an alphabet for his people. Pretty amazing!

Aerious

This word means airy.

I looked this up on Yahoo, here's a link:

The shortest word containing all five vowels exactly once is the six-letter EUNOIA, meaning alertness of mind and will (and also the title of a book by Canadian poet Christian Bok). However, it is not included in any major English dictionary. There are several seven-letter words containing all the vowels, including SEQUOIA, EULOGIA, MIAOUED, ADOULIE, EUCOSIA, EUNOMIA, EUTOPIA, MOINEAU, and DOULEIA. The relatively common French word OISEAU (meaning bird) contains all five vowels, once each, (since you didn't say "in the English language.") ;)
