[WHAT is The Longest English Word?]

Do you know what is the longest English word? Today I found in a news paper it is 'pneumonoultramicroscopicsilicovolcanoconiosis' and the meaning is "a lung disease caused by inhaling or breathing in particles of volcanic matter".
Any comments please let everybody know.
It has only 45 letters .

 

I can't even pronounce that properly, is that all in one word?

 

Wow! What else do you do on your free time? haha!

 

same lol now i feel dum

 

Its a single word my friend.

 

And then people say English is very easy language

 

if you run webzor check it out left some comments

 

I think the longest word is the name of a chemical or element, but I'm not going to try and spell it

 

lol...it is difficult to pronounce for me

Thanks for sharing

 

Wasnt the longest word something that started with 'supercalifrag.....??

 

That's what I thought, the phrase from Mary Poppins. Supercalifragolisticexpialodotioutus. Hmm...guess, not, that's only 35 characters lol.

 

The longest Welsh word:

Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch

It's the name of a small town.

The longest English used to be:

ACETYL­SERYL­TYROSYL­SERYL­ISO­LEUCYL­THREONYL­SERYL­PROLYL­SERYL­GLUTAMINYL­PHENYL­ALANYL­VALYL­PHENYL­ALANYL­LEUCYL­SERYL­SERYL­VALYL­TRYPTOPHYL­ALANYL­ASPARTYL­PROLYL­ISOLEUCYL­GLUTAMYL­LEUCYL­LEUCYL­ASPARAGINYL­VALYL­CYSTEINYL­THREONYL­SERYL­SERYL­LEUCYL­GLYCYL­ASPARAGINYL­GLUTAMINYL­PHENYL­ALANYL­GLUTAMINYL­THREONYL­GLUTAMINYL­GLUTAMINYL­ALANYL­ARGINYL­THREONYL­THREONYL­GLUTAMINYL­VALYL­GLUTAMINYL­GLUTAMINYL­PHENYL­ALANYL­SERYL­GLUTAMINYL­VALYL­TRYPTOPHYL­LYSYL­PROLYL­PHENYL­ALANYL­PROLYL­GLUTAMINYL­SERYL­THREONYL­VALYL­ARGINYL­PHENYL­ALANYL­PROLYL­GLYCYL­ASPARTYL­VALYL­TYROSYL­LYSYL­VALYL­TYROSYL­ARGINYL­TYROSYL­ASPARAGINYL­ALANYL­VALYL­LEUCYL­ASPARTYL­PROLYL­LEUCYL­ISOLEUCYL­THREONYL­ALANYL­LEUCYL­LEUCYL­GLYCYL­THREONYL­PHENYL­ALANYL­ASPARTYL­THREONYL­ARGINYL­ASPARAGINYL­ARGINYL­ISOLEUCYL­ISOLEUCYL­GLUTAMYL­VALYL­GLUTAMYL­ASPARAGINYL­GLUTAMINYL­GLUTAMINYL­SERYL­PROLYL­THREONYL­THREONYL­ALANYL­GLUTAMYL­THREONYL­LEUCYL­ASPARTYL­ALANYL­THREONYL­ARGINYL­ARGINYL­VALYL­ASPARTYL­ASPARTYL­ALANYL­THREONYL­VALYL­ALANYL­ISOLEUCYL­ARGINYL­SERYL­ALANYL­ASPARAGINYL­ISOLEUCYL­ASPARAGINYL­LEUCYL­VALYL­ASPARAGINYL­GLUTAMYL­LEUCYL­VALYL­ARGINYL­GLYCYL­THREONYL­GLYCYL­LEUCYL­TYROSYL­ASPARAGINYL­GLUTAMINYL­ASPARAGINYL­THREONYL­PHENYL­ALANYL­GLUTAMYL­SERYL­METHIONYL­SERYL­GLYCYL­LEUCYL­VALYL­TRYPTOPHYL­THREONYL­SERYL­ALANYL­PROLYL­ALANYL­SERINE

Which means 'Tobacco Mosaic Virus, Dahlemense Strain.' chemically speaking of course, but this was withdrawn because chemists didn't use it, or couldn't pronounce it or couldn't spell it.

 

Yup,It's really difficult to pronounce 'pneumonoultramicroscopicsilicovolcanoconiosis'

 

Now thats way too much

 

Wiki even has a page about it:
http://nl.wikipedia.org/wiki/Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch

And I remember the domain being sold as longest .nl / .com site or something
Forgot the hole story, but I still know he got a good sum of money

Greetz

 

Oh man...I'm getting nose bleeds just trying to read that

 

I tried 10+ time to pronounce it but failed

 

Honorificabilitudinitatibus is the longest word that I know. The longest word ever was mention before my post. It's some sort of a protein chemical. I think that word has almost 190K letters in it

 

My chemistry teacher has a large book that contains a very long chemical name in English....
