Longest word in the English language…

The longest word in the english language is pneaumonaultramicroscopicsilicovolcanoconiosis…It’s a lung disease contracted from breathing in too much volcanic dust settlement…

  1. RapMastaB is wrong – If it was replaced by another word, what was it? I’ll believe it is the longest until proven otherwise.

  2. not true – This WAS the longest word in the dictionary for a very long time, until a new one replaced it.

  3. Didn’t it… – Didn’t it used to be antidisestablishmentarianism? pneaumonaultramicroscopicsilicovolcanoconiosis seems too fake to me. Ya RapMastahB what is the new one? How the hell do you pronounce that last one? /me uses phonetics – know-mon-all-trah-my-crow-skop-icks-illy-koe-fulk-ah-know-konny-oh-sys.

  4. I thought this was the longest word: – floccinaucinihilipilification -> The act of finding out if something is wrong. It must have been bumped from its top spot.

  5. Using a keyboard, what’s the longest word, using only the left hand fingers? – It’s stewardesses!

  6. Incorrect!! – I believe that the longest word in the english language is the chemical name for Tryprophan Synthetase, a chemical that has something to do with sleep. Frankly though, I do not believe that there is enough space to type out the whole damn thing, and it would take far too long anyway.

  7. The longest has over 1900 letters!! – Hildi is right!!! The longest actual world is some chemical and it consists of over 1900 letters…..

  8. Etc…Miscellany – The longest word I know of is a couple hundred (Thousand?) letters that describe the cycle/metamorphisis of a cell.

  9. F – The letter “f” (Lower Case) is one of the only letters in the alphabet where more than 70% of it is written upwards

  10. 1909 letters, actually. – It isn’t really a word, it’s a chemical.

  12. crucify – holy crap…too many y’s…who would make a word that is THAT long anyhow? did they actually want to read it in the end?

  13. omg – that is one hell of a long word. I thought it was pneumonoultramicroscopicsilicovolcaniconiosis

  14. TOTALLY wrong. – pneaumonaultramicroscopicsilicovolcanoconiosis is the wrong spelling. It is spelled pneumonoultramicroscopicsilicovolcanoconiosis. I am 14 and I even know that! At least spell it right

  15. o MY GOsh – Isn’t this all swell…you guys have an awful lot of time on your hands..no offense or anything but like how do you find the time to write out these words letter by letter?????

  16. .. – Chemical names are only so long because they identify them by structure, the more complex a structure, the more complex the name, but I still feel that prefixes would have been used, 1-2-3 tri, tetra, dodeca, et cetera. However I will not even attempt to draw this chemical to see if I can give at a more abbreviated name, and dear Phoebe, It is not really that hard to type letter by letter… In fact there is no other way, but for this site, regarding Tryprophan Synthetase, I think someone went to a site it which the chemical was actually already written out, and just used Ctrl+C then Ctrl+V or Command+C then Command+V if they were on a mac.

  17. While I am at it…. – ZevioPiko: There are many names used to describe the cycle of a cell… and they are only about… 10-15 letters long… Just an approximation of letters.

    And on a more humourous note: The longest word is “Smiled.” Why? Because there is a mile between the first and the last letter.

  18. Oh My God!!!!!!!!!!! – i think yall need to get a life and quit reading the dictionary!! i mean hell, it’s called P-A-R-T-Y!!! hello?????????

  19. What??? – To boiledmoose Stop using those big fancy words!! And I thought language was a big word. Sheesh.

  20.

    ** – deoxyribonucleic acid (DNA) is alleged to have 207 000 letters, but has never been printed in full.

  21. So what? – To STLCutiePie3 I’m only 11 and I got a word more than 50 time s longer than yours so quit the show-offiness

  22. haha someone needs to learn to spell – its spelled pneumonoultramicroscopicsilicovolcanoconiosis
    not pneaumonaultramicroscopicsilicovolcanoconiosis sheesh if your goin to put a fact up make sure you can spell

  23. u ppl need to get a life – How about all u damn ppl get a damn life. Is that the only thing u guys kan do is write out these long-ass words letter-by-letter? You guys must have a lot of time on ur hands. You guys need to get a FRAGileING life.

  24. HELLO IM RANDOM – the longest word in the dictionary is…….supercalifragilisticakespialidocious………no, im only kidding, the longest word is “dog” now lets all go to bed and eat asparagus.

  25. O_O; – daaaamn, sum ppl did their homework… and took thirty minutes to write it out on the keyboard…

  26. UH.. – The only thing I can say is it’s sad how you all think you’re out-doing each other…sad sad sad…it’s such a shame how earth is going straight to hell…the longest word.. PATHETIC

  27. words – i thought that the longest word was the word that means “fear of long words” i dont remember wat it is

  28. >_> – First, to everyone saying “get a life, why are you doing this you nerds, etc”: If you hate us so much, why are you here?

    Anyway, someone who fears long words is hippomontrosesquipedelian, I believe… the spelling’s probably wrong though.

    Also, it would make sense that the complete word for DNA would be huge…

  29. i agree with the original fact – The longest word in the English language, according to the Oxford
    English Dictionary, is pneumonoultramicroscopicsilicovolcanoconiosis.
    The only other word with the same amount of letters is
    pneumonoultramicroscopicsilicovolcanoconioses, its plural.
    The longest place-name still in use is
    Taumatawhakatangihangakoauauotamateaturipukakapikimaungahoronukupokaiwh
    enuakita, a New Zealand hill

  30. wait a minute…i didnt get all the last one – The longest place-name still in use is
    Taumatawhakatangihangakoauauotamateaturipukakapikimaungahoronukupokaiwhenuakita natahu, a New Zealand hill.

  31. spelling – I think it’s rather sad that people are complaining about a spelling mistake in a thousand or so letter word but yet they themselves can’t even be bothered to spell their message correctly, or worse completely spell out a word. Like typing ppl instead of writing ‘people’ out. Come on, it’s not that much extra effort.

  32. you idiots – we are talking about the longest word in the dictionary. And when I said dictionary I meant “English Dictionary”. The word you are relating to a chemical is the scientific name of the chemical. Scientific names are derived from the Italian language and others but NOT ENGLISH! So think people! THINK!

  33. blah – A staggering 1913 letters. I mean come oON people who can beat this without making something up! and this is true, my dad is a scientist and i asked him if this was true and he said yes but they dont put it in the dictionary, you have to look it up on google.com methionylglutaminylarginyltyrosylglutamylserylleucylphenylalany

  34. ………. – DNA names are in the Science category not in the Languages category or to be more specific not even in the English dictionary. Try to think clearly as to what you are saying and what you are talking about.

  37. Good on yer santana and trivia queen – Good on u 2 cause those people who worte those long as words out wasted a hell of a lot of time and to u santana i have a FRAGileING life so i believe the longest word in the english language is Smiles (because there is a mile between the first and last letters.) =-)

  38. To berzirk – Thank you for noticing that i did silenced the pitiful morons who cannot distinguish what language English is!

  39. wrong – I thought that was the longest for a while. It’s a real word, also known as black lung disease (I’m pretty sure.) That chemical is the longest word, I actually looked it up in a dictionary I have of useless words. Also, Hippopotomonstrosesquippedaliophobia is the fear of long words. I’m not kidding.

  40. Words & Chemicals – Pneumonoultramicroscopicsilicovolcanokoniosis is definitely the longest word in the Oxford English Dictionary (the definitive unabridged English dictionary), and it does mean what the fact creator said it means (although he spelled it wrong). Chemical names are technically considered to be in “New Latin,” which is NOT the same as the original Latin (which, in fact, had no punctuation, lowercase, or even spaces), and it is most DEFINITELY not Italian (although there are similarities). It is essentially modified Latin expanded to include modern physical terms (no, Californium, Americium, Einsteinium, etc. where not in original Latin). Some of the names, such as Carbon-dioxide, have been included in English, but the more complex ones consisting of hundreds of letters have definitely not. I agree that any given chromosome (coiled strand of DNA) would probably have an extremely long (New Latin) name, considering the fact that it is a single molecule built up of billions of atoms, but there is no way anybody could determine the entire exact chemical makeup of a chromosome, decide its name using the rules of nomenclature, and write it out.

  41. ur all wrong – if ur talking about non-scientific thenOrnicopytheobiblopsychocrystarroscioaerogenethliometeoroaustrohieroanthropoi- cichthyopyrosiderochpnomyoalectryoophiobotanopegohydrorhabdocrithoaleuroalphi-tohalomolybdoclerobeloaxinocoscinodactyliogeolithopessopscphocatoptrotephraoeir-ochiroomychodactyloarithstichooxogeloscogastrogyrocerobletonooenoscapulinaniac- “A deluded human who practices divination or forecasting” (310 letters) is the longest

  42. typing dosen’t take that long – I can type 100 words per minute, but it’s in my own language
