What is the longest word in the English speaking world?

Answer 1

supercalifragilisticexpialidocious

Answer 2

The longest word in any major English language dictionary is pneumono­ultra­micro­scopic­silico­volcano­coniosis, a 45-letter word supposed to refer to a lung disease contracted from the inhalation of fine silica dust, but research has discovered that this word was originally intended as a hoax. It has since been used in a close approximation of its originally intended meaning, lending at least some degree of validity to its claim.[1]

Answer 3

I'm not totally sure, but back in the early 1990's I took a collegiate class called "Linguistics and Language History". Hardest class I ever took.

My professor told us the longest word in the English language was "antidisestablishmentarianism"...although with today's computer mumbo jumbo, it could have been beaten.

Good luck!

Answer 4

My mother checked out this Lists book from the library and in it, it listed the three longest words. I'm not sure if it's true or not, but it stated the longest word in was over a page long to write. I'm not going to attempt to write it, but it took over a page to write it.
