The longest word in any of the major English language dictionaries is pneumonoultramicroscopicsilicovolcanoconiosis, a word that refers to a lung disease contracted from the inhalation of very fine silica particles,[8] specifically from a volcano; medically, it is the same as silicosis. The word was deliberately coined to be the longest word in English, and has since been used in a close approximation of its originally intended meaning, lending at least some degree of validity to its claim.[4] The Oxford English Dictionary contains pseudopseudohypoparathyroidism (30 letters). Merriam-Webster's Collegiate Dictionary does not contain antidisestablishmentarianism, as the editors found no widespread, sustained usage of the word in its original meaning. The longest word in that dictionary is electroencephalographically (27 letters).[9] The longest non-technical word in major dictionaries is flocci­nauci­nihili­pili­fication at 29 letters. Consisting of a series of Latin words meaning "nothing" and defined as "the act of estimating something as worthless"; its usage has been recorded as far back as 1741.[10][11][12] Ross Eckler has noted that most of the longest English words are not likely to occur in general text, meaning non-technical present-day text seen by casual readers, in which the author did not specifically intend to use an unusually long word. According to Eckler, the longest words likely to be encountered in general text are deinstitutionalization and counterrevolutionaries, with 22 letters each.[13] A computer study of over a million samples of normal English prose found that the longest word one is likely to encounter on an everyday basis is uncharacteristically, at 20 letters.[14] The words Internationalization and localization are abbreviated "i18n" and "l10n", respectively, the embedded number representing the number of letters between the first and the last.
