Mary Poppins holds her hands out as blue butterflies fly past her.

“Supercalifragilisticexpialidocious” entered the world’s lexicon with little explanation and barely a definition after the release of ‘Mary Poppins’ in 1964. New words entering the cultural zeitgeist more recently happen often, since the dictionary makers allow slang words to appear in the reference book. The movie, ‘Mary Poppins’ tells the story of an English nanny who brought a fun but stern demeanor to a pair of upper-class children and their family. 

The song “Supercalifragilisticexpialidocious”, a silly and catchy tune performed by Julie Andrews and Dick Van Dyke, immediately became one of the most recognizable parts of the film. Even though the word is uttered ten times in the song, it can still be a fun tongue-twister for many. So, how do you pronounce “supercalifragilisticexpialidocious?” Trust us, you will not sound atrocious after you finish this article.

Nonsense, but With Meaning!

When Walt Disney and his namesake company were working on ‘Mary Poppins’, they hired a pair of brothers to help write the soundtrack for the movie. Richard and Robert Sherman became the music makers for this classic film and quickly began working on the music. 

The song, believe it or not, did not birth this word. In fact, versions of it stretch back to 1931, when writer Helen Herman appears to have first coined it. In writing an editorial for her college newspaper, ‘The Syracuse Daily Orange’, Herman gave the world this saccharinely sweet word of pure nonsense. 

How the Sherman brothers got hold of the word and turned it into one of Julie Andrews most enduring songs remains a mystery. Regardless of the context, the brothers received a copyright lawsuit over their use of it. The writers of a similarly sounding song called “Supercalafajalistickespialadojus,” sued Disney and the Shermans, but legal officials dismissed the suit.

We can finally get to the meaning with the word’s background firmly aside. Thanks to ‘Mary Poppins’, “supercalifragilisticexpialidocious” has a dictionary meaning. According to the Cambridge Dictionary, “supercalifragilisticexpialidocious” is an adjective denoting “extremely good”.

This meaning flies in the face of the word’s purpose in the song, “something to say when you have nothing to say.”

Julie Andrews and her husband at the time did find a way to add more to the song with an ad-libbed line. It took practice for Andrews to nail it, but like any consummate voice actor, she sang the word backward to add an extra layer of silliness to the proceedings. 

In an interview with NPR, while promoting her autobiography, Andrews revealed that she can still pronounce the word backward. Indeed, Andrews continues to have a vibrant acting legacy in large part thanks to her lead role in ‘Mary Poppins’. Her song still appears in popular culture, including for an audition on ‘The Voice’ in 2021.

Backward or forwards, “supercalifragilisticexpialidocious” is a complex word, one some might even call gibberish.

So, It’s Gibberish? 

At first glance, “supercalifragilisticexpialidocious” is gibberish, but its enduring legacy is that the most absurd words can evolve to mean something to everyone. Even the Sherman brothers acknowledged the word as one they would likely use as children to fill dead air. 

Any parent will tell you this behavior is par for the course for kids, especially when they are younger. After all, gibberish is part of any child’s language development

Even twin children often make up language to communicate with one another. That practice is called “cryptophasia” and it has been a subject of study by speech pathologists and psychologists for decades. 

So, made-up words are not a new phenomenon. Perhaps you have heard of the concept of “neologism,” defined as a “newly coined word or expression.” Neologisms and slang terms have sprung up with the rapid rise of the Internet in the past 30 years.

“Supercalifragilisticexpialidocious” is very much a neologism thanks to its introduction in ‘Mary Poppins’

Why Do People Struggle To Pronounce It? 

If you were to look at “supercalifragilisticexpialidocious” for the first time, you might get lost in the sheer tongue-twisting nature of the word’s construction.

At 34 letters long, “supercalifragilisticexpialidocious” is not even the longest word in the Dictionary. That honor is bestowed upon a 45-letter medical term that we will not even dare try to pronounce (you can take a crack at it, though): “Pneumonoultramicroscopicsilicovolcanoconiosis”. 

But, if you are among those who struggle to pronounce “supercalifragilisticexpialidocious”, a road map might be the best way to put you on the path to success.
