Question

Any ideas?

antidisenstablishmentaryismn.

Answer 2

The Oxford English Dictionary contains pseudopseudohypoparathyroidism (30 letters).

The longest non-technical word is flocci­nauci­nihili­pili­fication at 29 letters.

The longest officially recognized place name in an English-speaking country is Taumatawhakatangihangakoauauotamateaturipukakapikimaungahoronukupokaiwhenuakitanatahu (85 letters) which is a hill in New Zealand.

Names of chemical compounds can be extremely long if written as one word, which is sometimes done. An example of this is sodium­meta­diamino­para­dioxy­arseno­benzoe­methylene­sulph­oxylate, an arsenic-containing drug.

The longest technically legal Scrabble word in North American play is ethyl­enediamine­tetra­acetates (28 letters).

Answer 3

the longest word in the first OED was 29-letter floccinaucinihilipilification (the categorizing of something as worthless or trivial). The longest in the OED2, usually cited as the longest word in any English dictionary, is pneumonoultramicroscopicsilicovolcanoconiosis (a miners' lung disease caused by inhaling silica), 45 letters. Some scholars, however, deride this word as "made up," and declare '"floccinau...'" to be the champ. And, of course, there are some hippopotomonstrosesquipidelian (30 letters, means "long") words in specialized fields, especially chemistry, where they apparently just tack on another few letters every time they rewrite the textbooks. The full name of the tryptophan synthetase A protein, an enzyme with 267 amino acids, extends to 1,913 letters:
also a very long word often used today is "antidisestablishmentarianism"

Answer 7

pneumono­ultra­micro­scopic­silico­volcano­coniosis


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 volcanic ash, 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

Answer 8

the longest word (not a scientific word or something in latin) is antidisestablishmentarianism. From what I have heard, medical/latin words are not counted when giving credit to longest word in the english language

Answer 9

antidisestablishmentarianism - that's the longest word I know of in the dictionary.
