The Longest word in the world

Have you been dying to figure out the longest word in the world?  Well you have found it because here it is:

pneumonoultramicroscopicsilicovolcanoconiosis

I did not make this word up.  Her is the definition of this strange, but long, word:

pneu⋅mo⋅no⋅ul⋅tra⋅mi⋅cro⋅scop⋅ic⋅sil⋅i⋅co⋅ vol⋅ca⋅no⋅co⋅ni⋅o⋅sis   

[noo-muh-noh-uhl-truh-mahy-kruh-skop-ik-sil-i-koh-vol-key-noh-koh-nee-oh-sis, nyoo-]

–noun an obscure term ostensibly referring to a lung disease caused by silica dust, sometimes cited as one of the longest words in the English language.

It is hard to put this word in a sentence but I have figured out a good sentence for this word:

The doctor said that the deasease I have is called pneumonoultramicroscopicsilicovolcanoconiosis.  It is a very rare lung deasease that only about 5 people in the whole world have.
