The Longest Word is over 100,000 letters long and takes over 3 hours to prounce if pronouced correctly. If you want to know what it looks and how it is spelled, look it up on google because I'm not going to spend hours and hours just to write 1 damn word.

P.S - It is not an official word in the dictionary.
The Longest Word is too damn long.

There is a debate about the longest word in the English language; in my opinion it's floccinaucinihilipilificatious compared to the debate on antidisestablishmentarianism. Those with hippopotomonstrosesquippedaliophobia tend to avoid the subject. The longest word in the common English dictionary is pneumohoultramicroscopicsilicovolcanoko niosis, although in medical diaries and such methionylglutaminylarginyltyrosylglutam ylserylleucylphenylalanylalanylglutamin ylleucyllysylglutamylarginyllysylglutam ylglycylalanylphenylalanylvalylprolylph enylalanylvalylthreonylleucylglycylaspa rtylprolylglycylisoleucylglutamylglutam inylserylleucyllysylisoleucylaspartylth reonylleucylisoleucylglutamylalanylglyc ylalanylaspartylalanylleucylglutamylleu cylglycylisoleucylprolylphenylalanylser ylaspartylprolylleucylalanylaspartylgly cylprolylthreonylisoleucylglutaminylasp fraginylalanylthreonylleucylarginylalan ylphenylalanylalanylalanylglycylvalylth reonylprolylalanylglutaminylcysteinylph enylalanylglutamylmethionylleucylalanyl leucylisoleucylarginylglutaminyllysylhi stidylprolylthreoylisoleucylprolylisole ucylglycylleucylleucylmethionyltyrosyla lanylasparaginylleucylvalylphenylalanyl asparaginyllysylglycylisoleucylaspartyl glutamylphenylalanyltyrosylalanylglutam inylcysteinylglutamyllysylvalylglycylva lylaspartylserylvalylleucylvalylalanyla spartylvalylprolylvalylglutaminylglutam ylserylalanylprolylphenylalanylarginylg lutaminylalanylalanylleucylarginylhisti dylasparaginylvalylalanylprolylisoleucy lphenylalanylisoleucylcysteinylprolylpr olylaspartylalanylaspartylaspartylaspar tylleucylleucylarginylglutaminylisoleuc ylalanylseryltyrosylglycylarginylglycyl tyrosylthreonyltyrosylleucylleucylseryl arginylalanylglycylvalylthreonylglycyla lanylglutamylasparaginylarginylalanylal anylleucylprolylleucylasparaginylhistid ylleucylvalylalanyllysylleucyllysylglut amyltyrosylasparaginylalanylalanylproly lprolylleucylglutaminylglycylphenylalan ylglycylisoleucylserylalanylprolylaspar tylglutaminylvalyllysylalanylalanylisol eucylaspartylalanylglycylalanylalanylgl ycylalanylisoleucylserylglycylserylalan ylisoleucylvalyllysylisoleucylisoleucyl glutamylglutaminylhistidylasparaginylis oleucylglutamylprolylglutamyllysylmethi onylleucylalanylalanylleucyllysylvalylp henylalanylvalylglutaminylprolylmethion ylysylalanylalanylthreonylarginylserine reigns supreme. But in the science of deoxyribose nucleic acid (DNA) all amino acids have their own little tag. {eg. glutaminyl=C5H9N2O2 valyl=(CH3)2CHCH(NH2)CO} Therefore one strand of DNA could be lengthened out to an infinite amount of letters long.

The current longest accepted word in English dictionaries (above) is questioned also being as that it was coined by a man in 1935 simply for the purpose of creating a new longest word. Though pneumonoultramicroscopicsilicovolcanoco niosis does have a definition as a disease caused by inhalation of sulfuric dust in volcanic smoke, very prominent among mine workers and volcanic scientists.

As it is an open debate feel free to choose what you believe.

The longest word in the English language according to Guinness is FLOCCINAUCINIHILIPILIFICATION. The lung disease one is the longest unnofficial word, cos it's a compound scientific term, and it's possible to make sceintific names stupidly long, like the 1700+ character one, but that's neverbeen in a dictionary.

The longest word entered in a dictionary anywhere is Swedish, and it's NORDOSTERSJOKUSTARTILLERIFLYGSPANINGSSIMULATORANLAGG-
NINGSMATERIELUNDERHALLSUPPFOLJNINGSSYSTEMDISKUSSIONS-
INLAGGSFORBEREDELSEARBETEN, which means "preparatory work on the contribution to the discussion on the maintaining system of support of the material of the aviation survey simulator device within the north-east part of the coast artillery of the Baltic."

So, when sentences get excepted onto a word dictionary site, people begin to take up space on the side bar that can be seen while looking at a word on Urban Dictionary. For that, I have created the largest word on this site. The word means that a word on this site is getting a little out of hand.
Did you see the new word on Urban Dictionary?
