Question

Plese state some of the longest words in English with the most longest.

Answer 1

beleagued: There is a "league"(==approximately 3 miles and can vary) between the first and the last letters.

Just kidding, many of the answers above are correct, it is "PNEUMONO­ULTRA­MICRO­SCOPIC­SILICO­VOLCANO­CONIOSIS " or its alternative spelling "PNEUMONO­ULTRA­MICRO­SCOPIC­SILICO­VOLCANO­KONIOSIS"

Answer 2

The longest word in English depends upon the definition of what constitutes an English word. English allows new words to be formed by construction; long words are coined; place names may be considered words; technical terms may be arbitrarily long. Length can be in terms of orthography and number of written letters or phonology and the number of phonemes.

The longest word in any major English language dictionary is pneumono­ultra­micro­scopic­silico­volcano­coniosis,
The longest non-technical word is flocci­nauci­nihili­pili­fication.
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.
In his play Ecclesiazousae ("The Assemblywomen"), the ancient Greek comedic playwright Aristophanes created: Lopadotemachoselachogaleokranioleipsanodrimhypotrimmatosilphio-paraomelitokatakechymenokichlepikossyphophattoperisteralektryonop-tekephalliokigklopeleiolagoiosiraiobaphetraganopterygon, a word of 183 letters that describes a dish by stringing together its ingredients.
James Joyce made up nine 100 and one 101-letter words in his novel Finnegans Wake, the most famous of which is Bababadal­gharagh­takammin­arronn­konn­bronn­tonn­erronn­tuonn­thunn­trovarrhoun­awnskawn­toohoo­hoordenen­thurnuk. Appearing on the first page, it allegedly represents the symbolic thunderclap associated with the fall of Adam and Eve. As it appears nowhere else except in this passage, it is generally not accepted as a real word. Sylvia Plath made mention of it in her semi-autobiographical novel The Bell Jar, when the protagonist was reading Finnegans Wake.
"Supercalifragilisticexpialidocious", the 34-letter title of a song from the movie Mary Poppins, does appear in several dictionaries, but only as a proper noun defined in reference to the song title. The attributed meaning is "a word that you say when you don't know what to say."

**NOTE- Some of these words are being cut off because Yahoo thinks they are even too long! Use the link to look em up :)

Answer 3

The longest word in any major English language dictionary is pneumono­ultra­micro­scopic­silico­volcano­coniosis, a 45-letter word supposed to refer to a lung disease contracted from the inhalation of fine silica dust, but 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]

Answer 4

The longest off the top of my head is
pneumono­ultra­micro­scopic­silico­volcano­coniosis, but you should probably do some looking on your own to find out if I spelled it correctly or not.

Intrestingly enought it does not appear that yahoo answers will display it all. What I wrote has 45 letters.

Answer 5

Answer 6

It used to be antidisestablishmentarianism however the medical profession couldn't stand not having the longest word so they came up with a longer one. I am not sure now what it is.

Answer 7

Although longer neologisms have been used in literature, the longest "real" word I know is pneumonoultramicroscopicsilicavolcanoconiosis. There's probably something longer out there, though.
