Taking it as a riddle, the biggest word is "SMILES" because there is distance of a mile between two S.\nAcamedically, the biggest word in English is PNEUMONO­ULTRA­MICRO­SCOPIC­SILICO­VOLCANO­CONIOSIS (45), a lung disease. Oxford takes it as factitious.\n2nd biggest is HEPATICO­CHOLANGIO­CHOLECYST­ENTERO­STOMIES (37)

The answer really depends on what qualifies as a "word." \nFor example, chemical names can be thousands of letters long. If you wrote out the name of a DNA molecule, it would be over 1,000,000,000 letters. But are these really words? It seems even dictionaries can't agree. "Pneumonoultramicroscopicsilico-volcanoconiosis" is the longest word in non-technical English dictionaries, but according to the Oxford English Dictionary, it is a fictitious word created just to claim the title of longest. \nOne of the longest place names is 92 letters, the name of a hill in New Zealand that is typically called just "Taumata." And for those with a sense of humor, "smiles" is considered the longest word because there is a "mile" between the first and last letters.

....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

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. :-)

Then for your reference\n\nThe longest word currently in the Oxford English Dictionary is the supposed lung-disease "pneumonoultramicroscopicsilicovolcanoconiosis" (45 letters) but some editions of the Guiness Book of Records mention "aequeosalinocalcalinoceraceoaluminosocupreovitriolic" (52 letters), which is even longer.\n\nlongest chemical word for C1289H2051N343O375S8 is 0f (1909letters)\n\nit is \nmethionylglutaminylarginyltyrosylglutamylserylleucylphenylalanylalanylglutaminylleucyllysylglutamylarginy\n\nllysylglutamylglycylalanylphenylalanylvalyl\n\nprolylphenylalanylvalylthreonylleucylglycylaspartylprolylglycylisoleucylglutamylglutaminylserylleucyllysyl\n\nisoleucylaspartylthreonylleucylisoleucylglutamylalanylglycylalanylaspartylalanylleucylglutamylleucylglycyl\n\nisoleucylprolylphenylalanylserylaspartylprolylleucylalanylaspartylglycylprolylthreonylisoleucylglutaminyla\n\nsparaginylalanylthreonylleucylarginylalanylphenylalanylalanylalanylglycylvalylthreonylprolylalanylglutamin\n\nylcysteinylphenylalanylglutamylmethionylleucylalanylleucylisoleucylarginylglutaminyllysylhistidylprolylthre\n\nonylisoleucylprolylisoleucylglycylleucylleucylmethionyltyrosylalanylasparaginylleucylvalylphenylalanylasp\n\naraginyllysylglycylisoleucylaspartylglutamylphenylalanyltyrosylalanylglutaminylcysteinylglutamyllysylvalyl\n\nglycylvalylaspartylserylvalylleucylvalylalanylaspartylvalylprolylvalylglutaminylglutamylserylalanylprolylph\n\nenylalanylarginylglutaminylalanylalanylleucylarginylhistidylasparaginylvalylalanylprolylisoleucylphenylala\n\nnylisoleucylcysteinylprolylprolylaspartylalanylaspartylaspartylaspartylleucylleucylarginylglutaminylisoleu\n\ncylalanylseryltyrosylglycylarginylglycyltyrosylthreonyltyrosylleucylleucylserylarginylalanylglycylvalylthre\n\nonylglycylalanylglutamylasparaginylarginylalanylalanylleucylprolylleucylasparaginylhistidylleucylvalylala\n\nnyllysylleucyllysylglutamyltyrosylasparaginylalanylalanylprolylprolylleucylglutaminylglycylphenylalanylg\n\nlycylisoleucylserylalanylprolylaspartylglutaminylvalyllysylalanylalanylisoleucylaspartylalanylglycylalanyla\n\nlanylglycylalanylisoleucylserylglycylserylalanylisoleucylvalyllysylisoleucylisoleucylglutamylglutaminylhisti\n\ndylasparaginylisoleucylglutamylprolylglutamyllysylmethionylleucylalanylalanylleucyllysylvalylphenylalany\n\nlvalylglutaminylprolylmethionyllysylalanylalanylthreonylarginylserine\n\n\n\nPleze see it from the below site because yahoo replce some letter with ....

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.

It is the longest non-technical word word in the English language and means the act of calling something worthless or making something worthless by those means.  I honestly did know this word exsisted because I gave it as an answer to a question on here "What is the longest word?"  I didn't get best answer because the asker chose 'antidisestablishmentarianism', probally because he thought my answer of "floccinaucinihilipilification" was just made up. I took Latin at university for two years so yes, I could pronounce this word.

I've got one longer (1913 letters).
