This word has exactly 1787 letters. The hyphenation was done by hand, so it may look weird on some machines.

How is this possible? Words this long don't exist.
The word is made possible by the grammatical rules of the Finnish language. Finnish uses compound words instead of prepositions to describe complicated things. Take for example the word "rauta", iron. You can add the word "tie", road, to the end and get "rautatie", a railway. You can also add the word "hammas", a tooth, to the beginning to get "hammasrauta", braces (literally an iron of the tooth). The fun part is that it is grammatically correct to join these two words to get "hammasrautatie". This is a concise and compact word meaning a railway that runs on teeth or a road made of braces. (Although, being a pun, it is quite impossible to translate properly.) This word can then be extended to "hammasrautatietyö", which means repairs on the tooth railway and so on.

Is this really the longest word in the world?
That depends. It fulfills the following requirements:
It is grammatically correct.
No word within it is repeated.
All consecutive word pairs are meaningful.
However, these arguments suggest that it is not a word:
It isn't a word per se, it is just a combination of words.
Some word pairs aren't natural, they seem a bit forced.
The final decision depends on your definition of word. However this word is the longest word known by the authors that satisfies the three requirements listed above.

Answer 4

The longest word in the English language is supposed to be antidisestablishmentarianism I cannot confirm whether this is the longest off all languages.

However, I do have one of the longest

PNEUMONO­ULTRA­MICRO­SCOPIC­SILICO­VOLCANO­CONIOSIS

meaning:

a lung disease caused by breathing in particles of siliceous volcanic dus
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.

Answer 5

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, 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.[1]

The Oxford English Dictionary contains pseudopseudohypoparathyroidism (30 letters).

Answer 6

that fairly isn't a note, yet an really lengthy formula: Chemical words: 2 chemical words (3,641 and a million,913 letters lengthy) have regarded in the Guinness e book of international files. They were withdrawn because they have under no circumstances been utilized by using chemists, and there is not any theoretical reduce to the dimensions of conceivable valid chemical words. A DNA molecule would have a popularity of over a million,000,000,000 letters if it became written out in finished. (a million,185) ACETYL­SERYL­TYROSYL­SERYL­ISO­LEUCYL­TH...? = Tobacco Mosaic Virus, Dahlemense rigidity. This note has regarded in the yankee Chemical Society's Chemical Abstracts and is subsequently seen by using some to be the longest genuine note.
