adj. A word from the Disney film production of the book Mary Poppins describing any quality that is so indescribable that you have no real word to say it with

When you eat dirt for the first time and leave your family to build a shack in the woods

A fictitious word introduced in Mary Poppins. Thought to be a nonsense word, but it contains elements of real Greek and Latin roots:

super: above, over, extreme
cali: beauty
fragilistic: delicate
expiali: to atone, to make amends
docious: educable, able to learn

Very good word to confuse yourself.

A super big word that not many people can say.

If you say it loud enough, you'll aways sound precocious.

Multiple mispellings refer to the correctly spelled word "Supercalifragilisticexpialidocious" - a nonsense word uttered by the character, Mary Poppins in the 1964 movie of the same name. The Walt Disney production of the film, starring Julie Andrews as Mary Poppins, featured the word in a song that tells how you can use it to impress others or as an exclamation when you don't know what to say. (The movie, Mary Poppins, was based on the book of the same title, written by P L Travers in 1934.)
