what is the longest word in the us standard dictionary?

Agree with some of the choices posted by others. \n\nHere is my two cents worth and some trivia: \n\nFYI - Floccinaucinihilipilification is the longest word used in a commercial.  An insurance company (Geico?)commercial used this word in a spelling bee scenario.  All the kids are stunned. Even the judge seems baffled trying to use it in a sentence. The insurance company pledge, "No Hard Words".  See a link below for the word history.\n\nBut as mentioned in that link,"..(it was the longest in the first edition of the Oxford English Dictionary but was supplanted by pneumonoultramicroscopicsilicovolcanoconiosis in the second)...\n\nRegarding US Standard Dictionaries, at 45 letters long (45p) it appeared in the Webster's Third New International Dictionary, the Random House Dictionary of the English Language, Unabridged, and the Merriam-Webster's Collegiate Dictionary.\n\nSee Wiki source for the word origin.

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.

Sorry.. do you mean the longest word?\n"Antidisestablishmentarianism"  is the longest word in the english dictionary, if that's what you're talking about.

well she says it's a trick question....but I did a lil digging and if you want to be technical about it there is more then one word spelled in alphabetical order....\n\nThe longest word whose letters are in alphabetical order is the eight-letter Aegilops, a grass genus. The seven-letter addeems (from the archaic verb addeem, meaning to award), alloquy (an archaic or literary word for an address), beefily (in a beefy manner), billowy (like a wave or surge), dikkops (a South African bird) and gimmors (plural of gimmor, an old-fashioned word for a mechanical contrivance) are also close.\n\n\n\nas for the trick part... I don't get it! LOL

Antidisestablishmentarianism, is generally believed to be the longest English word. Abraham Lincoln, or some other politician ,used it in a speech or something. How that'll help you with your laundry is a mystery to me, but there you go!

elyas you are wrong!you are making it up\n\nDermatoglyphics, misconjugatedly, and uncopyrightable, each fifteen letters long, are the longest English words in which no letter appears more than once.

I think it is:  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.

No, supercalifragilisticexpialidocious is NOT the longest english word. Neither is antidisestablishmentarianism (although it's one of the most well known really long words). There's floccinaucinihilipilification (one letter longer than antidis...) and pneumonoultramicroscopic- silicovolcanoconiosis, at 45 letters, althought there's some dispute about that one, since it may have been made up for no other reason than to be a really long word.\n\nAnyway, back to supercalifragilisticexpialidocious... it doesn't mean anything. It's just a made up word that sounds really impressive. It's purpose (in the song) is to make the speaker sound intelligent ("...if you say it loud enough you'll always sound precocious"). \n\n"Of course, you could always say it backward, which would be docious-expi-ali- istic-cali-fragil-rupus, but that's going a bit too far, don't you think?"\n\nI listened to this song way too often in my childhood.

pneumonoultramicroscopicsilicovolcanoconiosis\n\n'a lung disease caused by the inhalation of very fine silica dust'\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 Jesse Helms, 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. The acceptability of the 33-letter adverbial form flocci­nauci­nihili­pilificastically is subject to controversy. The longest word in the Oxford English Dictionary is Pneumonoultramicroscopicsilicovolcanoconiosis, an invented word supposed to refer to a lung disease

According to the Oxford English Dictionary, the longest English word of one syllable is the ten-letter scraunched, appearing in a 1620 translation of Cervantes' Don Quixote. It is a largely obsolete form of scrunched or crunched.\n\nThe eleven-letter word broughammed (created by analogy with bussed, biked, carted etc.), while readily pronounceable as one syllable in all dialects ("broomed"), is yet to appear in a print dictionary. See: "ough" words.\n\nThe 10-letter word "squirreled" is arguably monosyllabic.\nhttp://en.wikipedia.org/wiki/List_of_the_longest_English_words_with_one_syllable

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.
