Supercalifragilisticexpialidocious is a whimsical, nonsensical word popularized by the 1964 Disney film Mary Poppins. It is used to describe something extraordinarily good, wonderful, or fantastic, often conveying excited approval or something great and extraordinary
. The word is a compound of several parts with playful meanings: "super-" (above), "cali-" (beauty), "fragilistic-" (delicate), "expiali-" (to atone), and "-docious" (educable), which together have been interpreted as "atoning for educability through delicate beauty"
. However, its primary use is as a fun, exaggerated expression rather than a word with a strict definition. In the film, the word is described as "something to say when you have nothing to say," emphasizing its playful, nonsensical nature
. It has since become a symbol of something extraordinarily good or impressive, especially among children and fans of Disney
. Though very long (34 letters), it is recognized as a real word in many dictionaries but is mostly used for fun or in literary and entertainment contexts rather than everyday language
. In summary, supercalifragilisticexpialidocious means extraordinarily good or wonderful, a playful and exaggerated way to express approval or delight, made famous by Mary Poppins
