When I was in grammar school we were told the longest word was antidisestablishmentarianism. We had a contest to see who could form the most words from it.

Looks like angelm's keyboard locked up ;-)

Justxploring, I was told the same thing you were told. I guess time changes...I can't even pronounce that word. :)

Well...up till now, I was only aware of only one word which was the longest.

It's called, Flauccinauccinihilipilification. Which means something of very small amount that it becomes immeasurable, thus making it so insignificant to use as proof or as an example.

Here's an example of that word:

If I paid 50 cents for a box of toothpics, and you asked me if I could sell you one toothpick, how much should I charge? It's too rediculous to even discuss, making it what the word stands for.
