The longest word in English has 189,819 letters and would take you three and a half hours to pronounce correctly. Seriously. It’s the chemical name of Titin (or connectin), a giant protein “that functions as a molecular spring which is responsible for the passive elasticity of muscle.” You can listen to a guy pronounce the whole damn word.
Supercalifragilisticexpialidocious this is not. In fact, you would need to say Supercalifragilisticexpialidocious over 5,000 times to come close to this word to come close to matching its letter count (go ahead, I’ll wait). If you want to see the word spelled out, it looks a lot like this:

That’s just the first part of the word too. The whole thing can be found in a 65KB textbit file here. You’re going to be scrolling for a very long time. For reference, the Internet says that Pride and Prejudice has about 120,000 words and the New Testament has about 180,000 words. And if you’re bold, you can watch the video above where the guy actually pronounces the whole damn thing (the flower doesn’t survive the pronunciation). [Geekologie via DesignTaxi]













The longest word I know is chemoorganoheterotrophs with a whopper of 23 letters.
I take your chemoorganoheterotrophs and raise you a antidisestablishmentarianism!
you two must come from Llanfairpwllgwyngyllgogerychwyrndrobwyll-llantysiliogogogoch………..hehhehehe
Should that not be an antidisestablishmentarianism ;
It should have been but I was in haste to share my long word and the edit button seems to have not been invented yet.
Also, shut your face!
I shall challenge your antidisestablishmentarianism and raise you a floccinaucinihilipilification
I prefer Pneumoultramicroscopicsilicovolcaniosis
I remember using the exact same word in a game of Extreme Scrabble for which I gained nearly 4,800,000 points and was such a massive win that as a prize, I won the year 2015. So be warned, things are going to change then.
I got 119 on double Triple-word tile for Brookies. Happy Days.
… Shark still looks fake…
Yes, but what does the word mean?
Look it up in the dictionary. I’m sure it’s supposed to be in there.
The word describes the pattern of atoms in a large organic molecule. It’s a more complicated instance of a word like ‘methane’ or ‘ethanol’.
The longest word I know is ‘infinity’…
First born child’s name sorted
I would actually attempt to read this word, or the other ones in the comment, but i cant. i suffer from Hippopotomonstrosesquipedaliophobia

I want to see Jonathan Ross do it
…and not take ANY breathes. Can’t do with that man.

This is like one of those infuriating facts on QI that is verging closely on bullshit.
Watching the video, you can literally see his beard grow.
He goes from clean shaven to stubble in 3 hours O_O
I wonder if that’s faked or not as part of a joke. If not it’s pretty amazing.
However, isn’t this just protein nomenclature that could be applied to any protein? It is basically just all the amino acids in order put together as one word.
It’s not really a word, it’s a chemical formula, it’s not a word in it’s true sense, it’s more like generating a very very large number (200,000 digits) writing it out and calling a word.
When loading up the comment I was going to say that I wanted a vid with all 3.5 hours of the pronunciation not actually expecting to see it…
