Whats the longest word in the english language?

[Saricharity]

Supercalifragilisticexpialidocious?

or

Floccinaucinihilipilification? that is a real word!!

or wait, I know...

Hippopotomonstrosesquipedaliophobia? I think I actually have this after trying to spell it right. Spell correct says I spelled it wrong.

So what is the longest word and what does it mean??

I heard somewhere years ago that it was "Antidisestablishmentarianism."

Do you want the longest word in the language or the longest word that's been used in a dictionary or other published literature? Don't know about the second, but there's no answer to the first. The way we are able to construct new words with affixes precludes it. Antidisestablishmentarianism is a good example--two prefixes and four suffixes attached to a rather common word.

 

[Wrexscar]

There are technical words and chemical and protein names that are longer but the longest word listed in standard, not technical dictionaries is antidisestablishmentarianism.
