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
Put together, "supercalifragilisticexpialidocious" translates roughly to "atoning for educability through delicate beauty" or "atoning for extreme and delicate beauty while remaining highly educable".
