What Is The Longest Word And What Does It Mean?

'Pneumonoultramicroscopicsilicovolcanoconiosis', with 45 letters, is widely acknowledged as the longest word in the English Language. It has appeared in a number of major English Language Dictionaries including Webster's Third New International Dictionary and Merriam-Webster's Collegiate Dictionary, Seventh Edition. It first appeared in the Oxford English Dictionary in 1936.

Its definition is an alleged lung disease caused by the inhalation of very fine silica dust found in volcanoes. It was originally coined to serve as the longest English word. However, the more general and widely used term for this condition is 'pneumoconiosis'.

There are a number of other words that have been created to suit a particular purpose but are not particularly well-known. For example, the ancient Greek playwright Aristophanes concocted the 183 letter word, 'Lopadotemachoselachogaleokranioleipsanodrimhypotrimmatosilphio-paraom
elitokatakechymenokichlepikossyphophattoperisteralektryonop-tekephalli
okigklopeleiolagoiosiraiobaphetraganopterygon'.  This was used to describe a particular dish by linking together its ingredients.

Often, the word 'anti­dis­establishment­arianism', with 28 letters, is often considered to be the longest word in regular use. This was a nineteenth century movement in England opposed to the separation of church and state.
