Pneumonoultramicroscopicsilicovolcanoconiosis

Pneumonoultramicroscopic

silicovolcanoconiosis

the longest word in the world is

There are longer words out there.

My favorite is Hippopotomonstrosesquipedaliophobia: fear of long words.

The longest one i've encountered is the long form of titin.

I don't remember but I know that longest word is chemical formula :D

I cant remember the word, but isn't the word that means a fear of long words? Quiet ironic isnt it lol
