The longest word in any major English language dictionary is\npneumono­ultra - ­micro­scopic­sili - co­volcano­coniosis, 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 approximation of its originally intended meaning, lending at least some degree of validity to its claim.\n\nThe Oxford English Dictionary contains pseudopseudo - hypoparathyroidism  (30 letters).\n\nThe longest non-technical word is \nflocci­nauc - i­nihili­pili­fication at 29 letters. Consisting of a series of Latin words meaning "nothing" and 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, and at the White House by Bill Clinton's press secretary Mike McCurry, albeit sarcastically.\n\n(Words hypenated because Yahoo was shortening them by cutting it off and using ...)

there's 'antidisestablishmentarianism' at 28 letters, meaning 'opposition to the disestablishment of the Church of England'. It is often considered the longest word as it has an actual meaning instead of being created just to be long.

"    * The longest common English word that can be typed using only the left hand (using conventional hand placement) is stewardesses. The words sweaterdresses and aftercataracts are longer and can also be typed with only the left hand, but they are not in all dictionaries.\n    * The longest English word that can be typed with the right hand only (using conventional hand placement) is johnny-jump-up, or alternatively polyphony.\n    * Typewriter is the longest word that can be typed on only one row, which might be no coincidence as some believe that Christopher Sholes deliberately placed all its letters in the top row when designing the layout in order to ease demonstrations. Proprietory, protereotype, and rupturewort are sometimes conjectured as the longest words but these are not available in most dictionaries."

To demonstrate the difficulty in counting words, over the centuries many scholars have attempted to count how many different words Shakespeare used in his corpus of work. The counts run anywhere from 16,000 to 30,000. It is thought that he contributed at least 2,000 new words to the English language. \n\nThe OED2, the largest English-language dictionary, contains some 290,000 entries. Of course, there are lots of slang and regional words that are not included and the big dictionary omits many proper names, scientific and technical terms, and jargon as a matter of editorial policy (e.g., there are some 1.4 million named species of insect alone). All told, estimates of the total vocabulary of English start at around three million words and go up from there.\n\nOf these, about 200,000 words are in common use today. An educated person has a vocabulary of about 20,000 words and uses about 2,000 in a week's conversation. (These estimates vary widely depending on who is doing the counting, so don't take them as absolute.)

FLOCCINAUCINIHILIPILIFICATION (29 letters; an estimation of something as worthless) but technically, this is no longer the longest word in the dictionary. This one is: PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS (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.)

....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". The Oxford English Dictionary described the word as factitious. 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

"smiles" is the longest word because there is a mile between the first letter and the last. :)
