The 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... [y] [w]

What a pun, indeed... that the definition of the word floccinaucinihilipilification is in fact just what floccinaucinihilipilification drives a person to think about such a word's usefulness to the English language... Accept the purpose of creating an extreme in vocabulary by which no man should ever... ever... go beyond, ever again. :-D

BTW... my spell check inside of MS Outlook Express actually has that word in its dictionary.

Mr.DictionaryThe longest words in the Oxford English Dictionary are Antidisestablishmentarianism, Floccinaucinihilipilification, and my favorite Pneumonoultramicroscopicsilicovolcanoconiosis.

Pronunsiation: Anti dis establishment arianism

Flocci nauci ni hilip ilification

pneumo ultra microscopic silico volcano con iosis
See this from Wikipedia:
However, the more serious problem is that the word was originally intended as a hoax: In Word Ways: The Journal of Recreational Linguistics , in several separate articles (May 1985, pp. 95-96; November 1986, pp. 205-206; May 1987, p. 82; November 1989, p. 205 [1] ), researchers discovered that the word was invented in 1935 by Everett M. Smith, president of the National Puzzlers' League , at their annual meeting. The word occurred in a newspaper headline about the meeting, after which it was picked up by an author of puzzle books. Members of the National Puzzlers' League then campaigned to have it included in major dictionaries, eventually succeeding with the Oxford English Dictionary and Webster's Second. Research into medical literature prior to 1935 has failed to find the word in the dictionary. It has since been used, albeit sparingly

btw, its spelled "antidisestablishmentarianism" with "establishment", not 'stablishment'...

From Wikipedia:

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, 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.

Actually ive found that the longest word is made up of over 207,000 letters. It represents the name for mitochondrial disease. Of cource im not going to post it due to the fact that it is so long, plus it is really hard to find someone that posts a word that long. Anyways, for

the ppl that made it said it wasnt supposedf to actually mean anything, but it still qualifies for a word b/c there are no repeated words, its grammatically correct, and it has a meaning, even if it is long. Plus the Finnish language strings words together to form a new one, much like german.

This the tabacco mosaic virus, dahlemense strain, a chemist's word, actually a word. People use it (at least the abbriviation) so it classifies as a real word. My favorite and only one to be able to spell is supercalifragilisticexpialidocious. 34 letters.
