Aside from that Welsh town, what is the longest word in use in the English language?

Answer 1

I know a word so long that it would cause the world's internet to come to a standstill if i posted it, so I better not say. Honest...

Answer 2

Antidisestablishmentarialism or something like that!

By the way Llanfairpwllgwyngyllgogerychwyndrobwyll-Llantissililgogogoch is Welsh therefore not in the English language and it is a place name not a word.

Answer 3

Well, "that Welsh town" isn't English anyway...

'Antidisestablishmentarian' [used of someone opposed to the disestablishment of the Church of England] used to be recognised as the longest word in 'regular' use - eg "speaking in the debate, the Bishop of Bath and Wells set out the antidisestablishmentarian position" - but it is not exactly in regular use now!

It will be good to see if anyone here comes up with a new one..

Answer 4

How can a Welsh place name be an English word?

Place names aren't words.. especially if it's in a different language!

But anyway...

I think it's..

pneumonaultramicroscopicsilicovolcanoconiosis

Answer 5

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 6

Antidisestablishmentarianism is the longest word in the English Dictionary/Language

Answer 7

Well so far all the big words that you found are Greek words put together. The question is about an English word i believe and the one i found is "Antidisestablishmentarianism" which means "the movement or ideology of advocates of opposition to disestablishment; the movement or ideology that opposes disestablishment".

Answer 8

I always thought it was Antidisestablishmentarianism.

chemical names don't count as they can be expanded to describe a complex formulea. They are not really subject to language or grammar testing. They can be considered proper nouns which can, of course, be anything you choose.

trust the dictionary not an unmoderated wikipedia

Answer 9

Ah, that's easy :)

Pneumoultramicroscopicsilicovolcanoconeosis

Although I see answers doesn't let it all fit on one line, so....
pneumoultramicroscopic
silicovolcanoconeosis

Also known as silicosis. Basically, its a cough - well, a lung disease to be more precise.

Another contender in more regular use is antidisestablishmentarianism (people who are against people who want to dis-establish the church of England)

Answer 10

Chemical term for the Tobacco Mosaic Virus, Dahlemense Strain...

It's to long to post here but it's 1185 letters long.
