The 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 (a p45 word for logologists) [citation needed], it is certainly the longest word ever to appear in a non-technical dictionary of English, Merriam-Webster's Third New International Dictionary (multiple editions)

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.

But scientific words don't count because they can always be compounded.\n\nFloccinaucinihilipilification ("the act or habit of esteeming or describing something as worthless") is the traditional Guinness Book of Records champion word.\n\nWikipedia actually has a nice article on other contenders:\nhttp://en.wikipedia.org/wiki/Longest_word_in_English

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. :-)

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

No such word in the English language. What language is it from?

the longest word that is actually a word and not a medical term, or a word that is only used in the context of 'the longest words,' that is to say- most of the words listed in the other answers are either medical terms or they are words that were created for the specific purpose of being the longest word- the longest word (non medical or created for long word purposes) is antidisestablishmentarianism

The Guiness Book Of World Record officially recognizes aequeosalinocalcalinoceraceoaluminosocupreovitriolic, which contains 52 letters, as the longest word. It is attributed to Dr Edward Strother (1675-1737).\n\nHowever, the longest word currently in the Oxford dictionary is pneumonoultramicroscopicsilicovolcanoconiosis, which is 45 letters long. It stands for a lung disease.\n\nFor more long words, please refer to the source.\n\nFrom a comic angle, the other answrer has already given an answer

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.
