What is the longest word in the dictionary?

[Shelton3369]

Hi, I'm wondering if anyone knows what the longest word is in the dictionary, and what it means?
I love to watch the National Spelling Bee every year.
Does anyone know?  

[The Man who was Thursday]

Presumably you mean the Oxford English Dictionary...

Thank you very much. My daughter finally told me what it was. It has 45 letters in the word. I know I couldn't never pronounce it or spell it.
Thanks for the website.  

[XxJennessaxX]

Wow.
And I thought Metacognition was the longest existing word.
Then, it would probably be "Supercalafragilisticexpialadocious."

 

[Sighren]

I always thought it was "Antidisestablishmentarianism." ^ ^  

[Smoozle]

I believe that it is "Antidisestablishmentarianism" Ha hey! Firefox didn't underline it! I feel special! Either that or "Pneumonoltramicroscopicsilicavolcanaconiosis" But I don't think that counts as it is a disease.

Hehe, hippopotomonstrosesquippedaliophobia. How ironic, all 37 letters of it.

Yes, but that isn't a word. It's a Phobia. The longest word is:

Is there a phobia for long words?

But that isn't in the dictionary!

^ I see spaces, so that doesn't make it one whole word, does it? Unless the spaces were done on accident.  

[Smoozle]

I see no spaces? There are enters at the end of the lines, otherwise it would be a real page stretcher!
