Move over, Mary Poppins, there’s a new tongue twister in town.
Sing this one out loud, sisters:

Jean-Étienne Liotard, Young Girl Singing into a Mirror, 1700s
Floccinaucinihilipilification!
(Need a spoonful of sugar?)
Unlike supercalifragilisticexpialidocious, floccinaucinihilipilification is a real (read: definitively definable) word. Saying it, however, is a challenge best broken into syllables.
Take a big breath and say it with me:
Flok
Suh
Naw
Suh
Nahy
Hil
Uh
Pil
Uh
Fi
KAY
Shuhn
Whew!
This rarely uttered Latin-based noun refers to an inherent lack of value. Something like, “The painting was forged by a copycat artist, so it was dismissed by the Antiques Roadshow as a floccinaucinihilipilification.”
But, the term’s primary claim to fame is its length—another one of the longest words in the English language.
Feeling pretty good about your pronunciation of floccinaucinihilipilification?
Try putting it to music.
