OMG OMG I ABSOLUTELY LOVE WORDS!!!!!!! I AM THE WORD FREAK OF MY SCHOOL I CARRY A DICTIONARY AND THESAURUS TO EVERY CLASS AND MY NICKNAMES ARE MISS WEBSTER 2006 AND DICTIONARY GIRL!!! I LOVE IT WHEN PEOPLE ASK ME THIS QUESTION!! It's hard to choose though!! I love them all so much! Okay, one of my favorites would have to be idiosyncratic, which means weird in one's own way, or strangely unique! My newest favorite is pneumonoultramicroscopicsilico-\nvolcanoconiosis, which is a supposed disease contracted from the overinhalation of silica dust. The disease does not really exsist, but that word is still my favorite, because it is the longest one I know! And, I can flawlessly spell it without looking! I have yet to find the longest word ever, though, but I can do it!

Hey man listen here!! Mr. Cannibal is answering you!!\nWords in this nature are natural.\nWhen languages use words it means they discovered the words not invented!\n Now I must answer your question that English has the most words because this is very old language and also absorbed many words from other languages during occupying other countries.\nBut you don’t have to memorize all of them.\nAlso Happy Birthday to you.

well she says it's a trick question....but I did a lil digging and if you want to be technical about it there is more then one word spelled in alphabetical order....\n\nThe longest word whose letters are in alphabetical order is the eight-letter Aegilops, a grass genus. The seven-letter addeems (from the archaic verb addeem, meaning to award), alloquy (an archaic or literary word for an address), beefily (in a beefy manner), billowy (like a wave or surge), dikkops (a South African bird) and gimmors (plural of gimmor, an old-fashioned word for a mechanical contrivance) are also close.\n\n\n\nas for the trick part... I don't get it! LOL

"PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS\n\n(45 letters; a lung disease caused by breathing in certain particles) is the longest word in any English-language dictionary. (It is also spelled -koniosis.)"\n\nor\n\nSMILES because "there's a mile between the two S's." :)

It is, in fact, Supercalifragilisticexpialidoc ious (space because it cuts me off otherwise).  That's what I thought, but I figured I'd better check...just in case.\n\nInterestingly, the longest common phrase is: ship-towed long-range acoustic detection system.\n\nI just discovered the other answer, and...wow.  I took this way, way too seriously.

"Euouae, six letters long, is the longest English word consisting only of vowels, and, also, the English word with the most consecutive vowels."

No. it is not. The well-known song title from the movie Mary Poppins, Supercalifragilisticexpialidocious, with 34 letters, does appear in several dictionaries, but only as a proper noun, and defined in reference to the song title. Hence it may well be dismissed as not a "real" word.\n\n\nThe Guinness Book of Records, in its 1992 and subsequent editions, declared the "longest real word" in the English language to be floccinaucinihilipilification at 29 letters. Defined as the act of estimating as worthless, its usage has been recorded as far back as 1741. In recent times its usage has been recorded in the proceedings of the United States Senate by Senator Jesse Helms, and at the White House by Bill Clinton's press secretary Mike McCurry. It is the longest non-technical word in the first edition of the Oxford English Dictionary.\n\n\nHowever, There are seemingly endless debates over what is the longest word in English, demonstrating that the idea of what constitutes a word is not as straightforward as it seems. Hyphenated or space-delimited compounds and proper nouns are linguistically considered words, but as they can grow with few limits, they are not counted.\n\nAntidisestablishmentarianism (a 19th century movement in England opposed to the separation of church and state) at 28 letters is often popularly accepted as English's longest word, and is probably the best-known "longest word." Other versions such as Antidisestablishmentarianistically and Pseudoantidisestablishmentarianism are demonstrably longer, though, showing that 'popular acceptance' is not a guarantee of accuracy. (See also the "Constructions" section below.) "Antidisestablishmentarianism" is actually used seriously in academic and ecclesiastical writing about the Church of England when the concept arises, and although one may suspect that authors have gone out of their way not to avoid it, it does thus have a serious claim to be the longest real word in current English.\n\nThe word pneumonoultramicroscopicsilicovolcanoconiosis, also spelled pneumonoultramicroscopicsilicovolcanokoniosis, is defined as "a lung disease caused by the inhalation of very fine silica or quartz dust." At 45 letters, it is certainly the longest word ever to appear in a non-technical dictionary of English, the Oxford English Dictionary. However there are strong indications that the word was coined by puzzler Everett Smith in 1935 as a hypothetical long word that could result from the protraction of medical terms. The actual name of the disease is pneumoconiosis, which is 14 letters long.\n\n\n\nA popular joke answer to the 'longest word' question is the word smiles, credited as the longest word because there is a mile between each s. Of course, by this reckoning the word beleaguered, which contains a league, is even longer.\n\nAccording to some, the longest word is the word after the sentence "And now, a word from our sponsors".\n\nAlthough only fourteen letters long, sesquipedalian deserves a mention. It is derived from a nonce word used by the Roman author Horace, in his work "Ars Poetica" (The Art of Poetry). The quote is as follows: "Proicit ampullas et sesquipedalia verba," which means, "He throws aside his paint pots and his words that are a foot and a half long". The Oxford English dictionary lists sesquipedalianism ("the practice of using words one and a half feet long"), and further derivations can be created as described in the "Constructions" section above.

Agree with some of the choices posted by others. \n\nHere is my two cents worth and some trivia: \n\nFYI - Floccinaucinihilipilification is the longest word used in a commercial.  An insurance company (Geico?)commercial used this word in a spelling bee scenario.  All the kids are stunned. Even the judge seems baffled trying to use it in a sentence. The insurance company pledge, "No Hard Words".  See a link below for the word history.\n\nBut as mentioned in that link,"..(it was the longest in the first edition of the Oxford English Dictionary but was supplanted by pneumonoultramicroscopicsilicovolcanoconiosis in the second)...\n\nRegarding US Standard Dictionaries, at 45 letters long (45p) it appeared in the Webster's Third New International Dictionary, the Random House Dictionary of the English Language, Unabridged, and the Merriam-Webster's Collegiate Dictionary.\n\nSee Wiki source for the word origin.

Hey Sethu, Since your question is posted in the "Words and Wordplay" section, I think the longest word in English should be the word 'SMILES'. How? From the start to the end, it is a MILE long. :-)
