The longest word in any major English language dictionary is Pneumonoultramicroscopicsilicovolcanoconiosis, a 45-letter word supposed to refer to a lung disease, but research has discovered that this word is a hoax. See the separate article for details.\n\nThe Guinness Book of Records, in its 1992 and subsequent editions, declared the "longest real word" in the English language to be floccinaucinihilipilification 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.\n\nI hope these links help.

Discipline.  The mind, which is associated with the human brain, is but a tool.  To get the maximum use out of any tool, one must practice.\n\nReading helps.  Working puzzles helps.  Answering questions helps.  Asking good questions helps.

There is no "Human Dictionary". \n\nHowever, the longest REAL word in the English language, according to The Guinness Book of Records, is "floccinaucinihilipilification" (29 letters) -  "the act of estimating (something) as worthless".\n\nThis doesn't count made-up words such as "pneumonoultramicroscopicsilicovolcanoconiosis", or "Bababadalgharaghtakamminarronnkonnbronntonnerronntuonnthunntrovarrhounawnskawntoohoohoordenenthurnuk," which only appears in James Joyce's novel, Finnegans Wake.\n\nSome very long names of places can be found at http://llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.com/\n\np.s. Those long words above are abbreviated, not my fault.  Seems that Yahoo! Answers doesn't like long words.  Anyway, see the source below if you want to see the whole word(s).
