has anyone got a definition of this word? it aint in the dictionary!!!?

It isn't in the dictionary because you spelt it wrong.

Try: Antidisestablishmentarianism

From the Oxford English Dictionary:

Properly, opposition to the disestablishment of the Church of England (rare): but popularly cited as an example of a long word.

1900 N. & Q. 25 Aug. 147/1 In the recent biography of Dr. Benson is an entry from the Archbishop's diary to the effect that ‘the Free Kirk of the North of Scotland are strong antidisestablishmentarians’. 1923 in Brewer's Dict. Phr. & Fable (new ed.) s.v. Long words. 1960 Amrita Bazar Patrika 17 June 6/4 But then ‘Antidisestablishmentarianism’ contains three more letters, as pointed out by two readers. 1984 T. AUGARDE Oxf. Guide Word Games xxvi. 216 The longest words that most people know are antidisestablishmentarianism..and supercalifragilisticexpialidocious.

Being opposed to the belief that there should no longer be an official church a the country. The word is sometimes quoted as the longest word in the English language. There is a town in Wales with a larger number of letters, but it is a place name, not a word.

Main Entry: antidisestablishmentarianism

Part of Speech: noun

Definition: originally, opposition to the disestablishment of the Church of England, now opposition to the belief that there should no longer be an official church in a country

Example: When people are asked for the longest word they know, they often say antidisestablishmentarianism.

Antidisestablishmentarianism originated in the context of the nineteenth century Church of England, where "antidisestablishmentarians" were opposed to proposals to remove the Church's status as the state church of England. The movement succeeded in England, but failed in Ireland and Wales, with the Church of Ireland being disestablished in 1871 and the Church in Wales in 1920. Antidisestablishmentarian members of the Free Church of Scotland delayed merger with the United Presbyterian Church of Scotland in a dispute about the position of the Church of Scotland. The term has largely fallen into disuse, although the issue itself is still current (see Act of Settlement 1701).

The word antidisestablishmentarianism, with 28 letters, is often quoted as being one of the longest English words that has an actual meaning (as opposed to words that were made up for the purpose of being long). In fact, its claim is quite good, since antidisestablishmentarianism is used seriously in academic and ecclesiasticalist writing about the Church of England when the concept arises, which it does occasionally (See e.g. Hastings and "Some notes on the Church of England and Establishment", below). However, since 1992 it has lost this title to floccinaucinihilipilification in the Guinness Book of Records. It might still be the longest word not invented for the specific purpose of being a long word, however, because the word floccinaucinihilipilification was invented as a joke and is an amalgamation of four different Latin words. Presumably it was made, at least partly, to make fun of long words. Also, some criticise its claim on the basis that it has two common prefixes ("anti-" and "dis"-) and no less than three suffixes ("-ment", "-arian" and "-ism"), stating that it is not only possible to create a number of longer meaningful words by adding yet more prefixes, but that "antidisestablishmentarianism" is not a standalone word because of them.

The correct spelling is antidisestablishmentarianism.

I don't know the meaning of that word. But i got another word which i think is the longest? need it????

Sounds like someone from Montana that got hit in the head by a rock!

Contextually, it refers to the disassociation of the church as a political or state entity, specifically referring to the Church of England. The Anglican church was "disestablished" as the official state church.

It would be in an unabridged dictionary, you spelled it wrong though.
