I think this is the longest word in the world!!
what does it means
It's almost certainly the 'name' of a protein. Proteins are long sequences of individual amino-acids. The 'yl' combination occurs frequently and more or less each part in between them is the chemical name of a separate group or stem of an organic compound.

DNA is an extremely long sequence of such amino acids. I think the DNA sequence is even longer than this. Every year several new sequences are unravelled and this one may well have been quoted in a student magazine some years ago and has been copied and pasted over and over again since then. I don't really know which one this is.

Such sequences are of interest only to organic chemists and they usually use a shorthand formula to represent each aminoacid in the sequence rather than writing out the names like this.

This very confusing form of name is usually only quoted for this type of so-called 'longest word'.

ya right i just found one wayyy longer than this punny word muhahahahahaahaahaahhahahhaha ha
Hello, this is Uzair,no doubt that might be the longest word,but what 's the meaning of this word.

Thanks.......Emotion: smile
FLOCCINAUCINIHILIPILIFICATION at 29 letters is in fact the longest legit word, since Pneumonoultramicroscopicsilicovolcanoconiosis at 45 letters was created solely for the purpose of the longest word in the English language.

The longest word is in fact FLOCCINAUCINIHILIPILIFICATION @ 29 letters since pneumonolutramicroscopicsilicovolcanoconiosis @ 45 letters was created solely for the purpose of the longest word in the English language. Proteins can have additional amino-acids added to make longer words, so therefore, they cannot be legit words. They are in the sense "add-ons."

The guy who you all tought was typing a bunch of jibberish, it is actually a word. It is a long word. I quote:

"Tobacco Mosaic Virus, Dahlemense Strain.
This word has appeared in the American Chemical Society's Chemical Abstracts and is thus considered by some to be the longest real word."

that is what the word means. It is a chemical word, because majority of chemical names are confusing and long. But it is a real word, and one of the longest words in the world. Here ya' go:

Two chemical terms (3,641 and 1,913 letters long) have appeared in the Guinness Book of World Records. They were withdrawn because they have never been used by chemists, and there is no theoretical limit to the length of possible legitimate chemical terms. A DNA molecule could have a name of over 1,000,000,000 letters if it was written out in full.

Chow.
PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS (45 letters; a lung disease caused by breathing in certain particles) is the longest word in any English-language dictionary. (It is also spelled -koniosis.)

great job looking it up in the dictonary and finding out what it is some people are making big jokes about it.
