The Largest Word(s) in English (Hint: Not from Mary Poppins)

largest-wordIn any of the major English dictionaries, this word is the longest.  It’s a medical term, (go figure) so I don’t know how anyone else would know this.  Why don’t we turn this into a writing prompt too?  If you can put it in a piece of your story, share in the comments section down below!  🙂  

Okay. *drum roll*

Pneumonoultramicroscopicsilicovolcanoconiosis

(45 letters)

It means a lung disease that you can get from inhaling very fine silica particles, more specifically from volcanoes.  (It is the same as silicosis medically) (Source)

I dare you to go up to someone who is in the medical profession, and ask them what this word means.  Just for fun. 😛

 

BUT!

That’s not the longest word.  That was just the longest word found in most major dictionaries.  This is the longest word in English.  189,819 letters.  It would take you 3.5 hours to correctly pronounce it.  I’ll just put the first forty lines in here…  It goes on for 878 of these.  (It’s the name of the largest protein known today)
