the longest word that is actually a word and not a medical term, or a word that is only used in the context of 'the longest words,' that is to say- most of the words listed in the other answers are either medical terms or they are words that were created for the specific purpose of being the longest word- the longest word (non medical or created for long word purposes) is antidisestablishmentarianism

OMG OMG I ABSOLUTELY LOVE WORDS!!!!!!! I AM THE WORD FREAK OF MY SCHOOL I CARRY A DICTIONARY AND THESAURUS TO EVERY CLASS AND MY NICKNAMES ARE MISS WEBSTER 2006 AND DICTIONARY GIRL!!! I LOVE IT WHEN PEOPLE ASK ME THIS QUESTION!! It's hard to choose though!! I love them all so much! Okay, one of my favorites would have to be idiosyncratic, which means weird in one's own way, or strangely unique! My newest favorite is pneumonoultramicroscopicsilico-\nvolcanoconiosis, which is a supposed disease contracted from the overinhalation of silica dust. The disease does not really exsist, but that word is still my favorite, because it is the longest one I know! And, I can flawlessly spell it without looking! I have yet to find the longest word ever, though, but I can do it!

The acceptability of the 33-letter adverbial form flocci­nauci­nihili­pilificastically is subject to controversy. The longest word in the Oxford English Dictionary is Pneumonoultramicroscopicsilicovolcanoconiosis, an invented word supposed to refer to a lung disease.
