The Guinness Book of Records, in its 1992 and subsequent editions, declared the "longest real word" in the English language to be flocci­nauci­nihili­pilificati... at 29 letters. Defined as "the act of estimating (something) as worthless", its usage has been recorded as far back as 1741. In recent times its usage has been recorded in the proceedings of the United States Senate by Senator Jesse Helms, and at the White House by Bill Clinton's press secretary Mike McCurry, albeit sarcastically. It is the longest non-technical word in the first edition of the Oxford English Dictionary. The acceptability of the 33-letter adverbial form flocci­nauci­nihili­pilificast... is subject to controversy. The longest word in the Oxford English Dictionary is Pneumonoultramicroscopicsilico... an invented word supposed to refer to a lung disease.

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

"    * The longest common English word that can be typed using only the left hand (using conventional hand placement) is stewardesses. The words sweaterdresses and aftercataracts are longer and can also be typed with only the left hand, but they are not in all dictionaries.\n    * The longest English word that can be typed with the right hand only (using conventional hand placement) is johnny-jump-up, or alternatively polyphony.\n    * Typewriter is the longest word that can be typed on only one row, which might be no coincidence as some believe that Christopher Sholes deliberately placed all its letters in the top row when designing the layout in order to ease demonstrations. Proprietory, protereotype, and rupturewort are sometimes conjectured as the longest words but these are not available in most dictionaries."
