Floccinaucinihilipilification (29 letters), is famous for being the longest word in the Oxford English Dictionary, however, this is now only true of the first edition, the second edition contains a few even-longer words. The word itself was a joke word of the 18th and 19th century literati, stemming from an Eton grammar school Latin drill. \n\ndefinition: an estimation of something as worthless.

PNEUMONO­ULTRA­MICRO­SCOPIC­SILICO­VOLCANO­CONIOSIS (also spelled PNEUMONO­ULTRA­MICRO­SCOPIC­SILICO­VOLCANO­KONIOSIS) = a lung disease caused by breathing in particles of siliceous volcanic dust.\nThis is the longest word in any English dictionary. However, it was coined by Everett Smith, the President of The National Puzzlers' League, in 1935 purely for the purpose of inventing a new "longest word". The Oxford English Dictionary described the word as factitious. Nevertheless it also appears in the Webster's, Random House, and Chambers dictionaries.

Hi there,\n\nWe do have genuine (if rather obviously deliberate) examples in our files of antidisestablishmentarianism (28 letters) and floccinaucinihilipilification (29 letters), which are listed in some of our larger dictionaries. Other words (mainly technical ones) recorded in the complete Oxford English Dictionary include: \n\notorhinolaryngological (22 letters), \nimmunoelectrophoretically (25 letters), \npsychophysicotherapeutics (25 letters), \nthyroparathyroidectomized (25 letters), \npneumoencephalographically (26 letters), \nradioimmunoelectrophoresis (26 letters), \npsychoneuroendocrinological (27 letters) \nhepaticocholangiogastrostomy (28 letters), \nspectrophotofluorometrically (28 letters), \npseudopseudohypoparathyroidism (30 letters). \n\nMost of the words which are given as 'the longest word' are merely inventions, and when they occur it is almost always as examples of long words, rather than as genuine examples of use. For example, the medieval Latin word honorificabilitudinitas (honourableness) was listed by some old dictionaries in the English form honorificabilitudinity (22 letters), but it has never really been in use. The longest word currently listed in Oxford dictionaries is rather of this kind: it is the supposed lung-disease  pneumono ultra microscopic silico volcanoconiosis (45 letters). \n(no space is there between the letters. I have added a space because here it is being showed as ...)\n\nrule wid style n luv@vinny

Longest non technical word is \n\nfloccinaucinihilipilification\n\nLongest technical word is \n"pneumonoultramicroscopic- \nsilicovolcanoconiosis" \n\n(it is the name of a lung disease caused by inhaling fine mineral dust)\n\nIt is a common misconception that "Antidisestablishmentarianism" \nis the longest word.\n\nI had to hyphenate the technical word because yahoo was truncating it for some reason. It is not hyphenated in its correct spelling.

The longest word in any major English language dictionary is Pneumonoultramicroscopicsilicovolcanoconiosis, a 45-letter word supposed to refer to a lung disease, but research has discovered that this word was originally intended as a hoax. It has since been used in a close approxmation of its originally intended context, lending at least some degree of validity to its claim. See the separate article for details.\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 (something) 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 Robert Byrd [1], and at the White House by Bill Clinton's press secretary Mike McCurry, albeit sarcastically. It is the longest non-technical word in the first edition of the Oxford English Dictionary.\n\nAntidisestablishmentarianism (a 19th century movement in England opposed to the separation of church and state) at 28 letters is one of English's longest words.\n\nThe longest word which appears in William Shakespeare's works is the 27-letter honorificabilitudinitatibus, appearing in Love's Labour's Lost. This is arguably an English word (rather than Latin), but only because he used it.\n\nThe humuhumu-nukunuku-a-pua‘a, or reef triggerfish, is Hawaii's official state fish [1]. At 21 letters (22 counting the okina) it is one of the best known very long one-word names for an animal. It is often asserted that "the name is longer than the fish."\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[2] 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 below.

....according to this.....the official longest word is under the chemical section containg 3,641 and 1,914(not listed); and listed with 1,185 letters........\n\nLongest Words\n(45) PNEUMONO­ULTRA­MICRO­SCOPIC­SILICO­VOLCANO­CONIOSIS (also spelled PNEUMONO­ULTRA­MICRO­SCOPIC­SILICO­VOLCANO­KONIOSIS) = a lung disease caused by breathing in particles of siliceous volcanic dust.\nThis is the longest word in any English dictionary. However, it was coined by Everett Smith, the President of The National Puzzlers' League, in 1935 purely for the purpose of inventing a new "longest word".

Nevertheless it also appears in the Webster's, Random House, and Chambers dictionaries.\n(37) HEPATICO­CHOLANGIO­CHOLECYST­ENTERO­STOMIES = a surgical creation of a connection between the gall bladder and a hepatic duct and between the intestine and the gall bladder.\nThis is the longest word in Gould's Medical Dictionary.\n\n(34) SUPER­CALI­FRAGI­LISTIC­EXPI­ALI­DOCIOUS = song title from the Walt Disney movie Mary Poppins.\nIt is in the Oxford English Dictionary.\n\n\n"But then one day I learned a word\nThat saved me achin' nose,\nThe biggest word you ever 'eard,\nAnd this is 'ow it goes:\nSupercalifragilisticexpialidocious!"\n(30) HIPPOPOTO­MONSTRO­SESQUIPED­AL­IAN = pertaining to a very long word.\nFrom Mrs. Byrne's Dictionary of Unusual, Obscure and Preposterous Words.\n\n(29) FLOCCI­NAUCINI­HILIPIL­IFICATION = an estimation of something as worthless.\nThis is the longest word in the first edition of the Oxford English Dictionary. Interestingly the most common letter in English, E, does not appear in this word at all, whilst I occurs a total of nine times. The word dates back to 1741. The 1992 Guinness Book of World Records calls flocci­nauci­nihili­pilification the longest real word in the Oxford English Dictionary, and refers to pneumono­ultra­micro­scopic­silico­volcano­koniosis as the longest made-up one.\n\n(28) ANTI­DIS­ESTABLISH­MENT­ARIAN­ISM = the belief which opposes removing the tie between church and state.\nProbably the most popular of the "longest words" in recent decades.\n\n(27) HONORI­FICABILI­TUDINI­TATIBUS = honorableness.\nThe word first appeared in English in 1599, and in 1721 was listed by Bailey's Dictionary as the longest word in English. It was used by Shakespeare in Love's Labor's Lost (Costard; Act V, Scene I):\n\n\n"O, they have lived long on the alms-basket of words.\nI marvel thy master hath not eaten thee for a word;\nfor thou art not so long by the head as\nhonorificabilitudinitatibus: thou art easier\nswallowed than a flap-dragon."\nShakespeare does not use any other words over 17 letters in length.\n\n(27) ELECTRO­ENCEPHALO­GRAPHICALLY\nThe longest unhyphenated word in Merriam-Webster's Collegiate Dictionary (10th Ed.), joint with ethylene­diamine­tetraacetate (see below).\n\n(27) ANTI­TRANSUB­STAN­TIA­TION­ALIST = one who doubts that consecrated bread and wine actually change into the body and blood of Christ.\n\n(21) DIS­PRO­PORTION­ABLE­NESS and (21) IN­COM­PREHEN­SIB­ILITIES\nThese are described by the 1992 Guinness Book of World Records as the longest words in common usage.\n\nSome say SMILES is the longest word because there is a MILE between the first and last letters!\n\n\n\n--------------------------------------------------------------------------------\n\n\nChemical Terms\nTwo chemical terms (3,641 and 1,913 letters long) have appeared in the Guinness Book of World Records. They were withdrawn because they have never been used by chemists, and there is no theoretical limit to the length of possible legitimate chemical terms. A DNA molecule could have a name of over 1,000,000,000 letters if it was written out in full.\n(1,185) ACETYL­SERYL­TYROSYL­SERYL­ISO­LEUCYL­THREONYL­SERYL­PROLYL­SERY

Appearing on the first page, it allegedly is the symbolic thunderclap representing the fall of Adam and Eve. As this word appears nowhere else except in reference to this passage, it is generally not accepted as a real word. Sylvia Plath made mention to that word in her semi-autobiographical novel The Bell Jar as Esther Greenwood, the protagonist, was reading Finnegans Wake.\n\nThe 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, particularly since the song assigns no meaning to it other than to say it's impressive.\n\nIn the 1970s, there were advertisements for Lip­smackin­thirst­quenchin­acetastin­motivatin­good­buzzin­cool­talkin­high­walkin­fast­livin­ever­givin­cool­fizzin Pepsi, coining a 100-letter term.
