Supercalifragilisticexpialidocious

Origin and meaning

According to Richard M. Sherman, co-writer of the song with his brother, Robert, the word was created by them in two weeks, mostly out of double-talk.

The roots of the word have been defined as follows: super- "above", cali- "beauty", fragilistic- "delicate", expiali- "to atone", and docious- "educable", with the sum of these parts signifying roughly "Atoning for educability through delicate beauty."

According to the film, it is defined as "something to say when you have nothing to say".
