I read an article “Joy of sesquipedalians” from the book ‘Ex Libris’ by Anne Fadiman which introduced me to ‘Sesquipedalians’. A polysyllabic/long word is called Sesquipedalian.

Like paradimethylaminobenzaldehyde , it is an organic compound containing amine and aldehyde moieties.

Here’s some more Sesquipedalians I collected from the web.

antidisestablishmentarianism (28) : the movement or ideology that opposes disestablishment

Hippopotomonstrosesquipedaliophobia: The fear of long words.

Pneumonoultramicroscopicsilicovolcanoconiosis : “a lung disease caused by the inhalation of very fine silica dust, causing inflammation in the lungs.”

floccinaucinihilipilification‘the action of estimating something as worthless’

Honorificabilitudinitatibus: “the state of being able to achieve honours”

Supercalifragilisticexpialidocious“, the 34-letter title of a song from the movie Mary Poppins, does appear in several dictionaries, but only as a proper noun defined in reference to the song title. The attributed meaning is “a word that you say when you don’t know what to say.” The idea and invention of the word is credited to songwriters Robert and Richard Sherman.

Lake Chaubunagungamaug, also known as Webster Lake, is a lake in the town of Webster, Massachusetts, United States. It is located near the Connecticut border and has a surface area of 1,442 acres (5.84 km2).

    1. Haha… Isn’t it funny, even this word is long, it should have been shorter. How can one say “I have hippopotp… hippopotomon…. hippopoto blah blah blah” 🙂

  1. Holy moses–I passed out just trying to say those words! But I am heartened by the fact that, despite being old, apparently I can learn something new. 🙂
