Question

what is the longest word in the english language

Answer 1

[edit] Major dictionaries
The longest word in any of the major English language dictionaries is pneumonoultramicroscopicsilicovolcanoconiosis, a 45-letter word which refers to a lung disease contracted from the inhalation of very fine silicious particles. 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.[1]

The Oxford English Dictionary contains pseudopseudohypoparathyroidism (30 letters).

The longest non-technical word in major dictionaries is flocci­nauci­nihili­pili­fication 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.[2][3][4] In recent times its usage has been recorded in the proceedings of the United States Senate by Senator Robert Byrd [5], and at the White House by Bill Clinton's press secretary Mike McCurry, albeit sarcastically.[6]

[edit] Other notable long words
Anti­dis­establishment­arianism (a nineteenth century movement in England opposed to the separation of church and state) at 28 letters is still in colloquial currency for being one of the longest words in the English language.

The 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), only because it was Shakespeare who used it.

The humuhumunukunukuapua‘a, or reef triggerfish, is Hawaii's official state fish.[7] At 22 letters (including the okina), it is one of the best known very long one-word names for an animal. It is occasionally quipped that the name is longer than the fish.

Answer 2

This 1185-letter "word" is the chemical name for "Coat Protein, Tobacco Mosaic Virus, Dahlemense Strain". It is supposedly the longest word in the English language. The term was published in the American Chemical Society's Chemical Abstracts in 1972, and is considered by some to be the longest real word. It does hold the record for the longest word published in an English language publication in a serious context - that is, for some reason other than to publish a very long word. In its complete form, the 1185-letter word is: acetylseryltyrosylserylisoleucylthreon...

Answer 5

This first one I had to break into two parts in order for it to appear on the page. But it is actually one long word:

PNEUMONO­ULTRA­MICRO­SCOPIC
SILICOVOLCANOCONIOSIS = a lung disease caused by breathing in particles of siliceous volcanic dust.
This 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.

HEPATICO­CHOLANGIO­CHOLECYST­ENTERO­STOMIES = a surgical creation of a connection between the gall bladder and a hepatic duct and between the intestine and the gall bladder.
This is the longest word in Gould's Medical Dictionary.

HONORI­FICABILI­TUDINI­TATIBUS = honorableness.
The 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):
