[MARY POPPINS]
Super... calif... ragil... istic... expialid... ocious! Ha!

[MICHAEL, spoken]
That's not a word!

[MARY POPPINS]
Of course it's a word, and unless I'm very much mistaken, I think it's going to prove a rather useful one

(sung)
When trying to express oneself, it's frankly quite absurd
To leaf through lengthy lexicons to find the perfect word
A little spontaneity keeps conversation keen
You need to find a way to say, precisely what you mean...

Supercalifragilisticexpialidocious!
Even though the sound of it is something quite atrocious
If you say it loud enough, you'll always sound precocious!
Supercalifragilisticexpialidocious!

[MARY POPPINS + ENSEMBLE]
Um-diddle-diddle-um-diddleye
Um-diddle-diddle-um-diddleye

[MICHAEL, spoken]
But it doesn't mean anything!
[ENSEMBLE]
Um-diddle-diddle-um-diddleye
Um-diddle-diddle-um-diddleye

[MARY POPPINS, spoken]
It can mean exactly what you want it to

(sung)
When stone age men were chatting, simply grunting would suffice

[BERT]
Now if they heard this word, they might have used it once or twice!

[MRS. CORRY]
I'm sure Egyptian Pharaohs would have grasped it in a jiff
Then every single pyramid would bear this hieroglyph;

Oh!
Supercalifragilisticexpialidocious!
Say it and wild animals would not seem so ferocious!

[MARY POPPINS]
Add some further flourishes, it's so rocococoscious!

[MRS. CORRY]
Ah
[MARY POPPINS]
Ah

[BERT]
Ah ah ah ah

[BERT]
The Druids could have carved it on their mighty monoliths!

[MRS. CORRY]
The ancient Greeks I'm certain would have used it in their myths!

[MARY POPPINS]
I'm sure the Roman Empire only entered the abyss
Because those Latin scholars never had a word like this!

[ALL]
Supercalifragilisticexpialidocious!
[MARY POPPINS]
If you say it softly the effect can be hypnotious!

[BERT]
Check your breath before you speak, in case it's halitotious!

[MARY POPPINS, spoken]
Of course you can say it backwards, which is Suoicodilaipxecitsiligarfilacrepus

[MICAHEL]
She may be tricky, but she's bloody good!

[MARY POPPINS, sung]
So when the cat has got your tongue, there's no need for dismay!
Just summon up this word and then you've got a lot to say!

[BERT]
Pick out those eighteen consonants and sixteen vowels as well
And put them in an order which is very 'ard to spell -
