Supercalifragilisticexpialidocious

~is an English word in the song with the same title in the musical film Mary Poppins

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