no, pneumonoultramicroscopicosillicovolcanoconiosis is the longest word.
It is a long name for a form of the lung disease "silicosis". The word was created in 1935 at the National Puzzlers Convention with the aim of being the longest dictionary word. It did not succeed for the most part but is often promoted as "the longest word in the English language" at 45 letters (the hyphen is added here to allow it to display).
Pneumonoultramicroscopicsilicovolcanoconiosis is, according to the Oxford English Dictionary, "a factitious word alleged to mean 'a lung disease caused by the inhalation of very fine silica dust, causing inflammation in the lungs.'" A condition meeting the word's definition is normally called silicosis. The 45-letter word is the longest word ever to appear in an English language dictionary and is listed in the current edition of several dictionaries. Pneumonoultramicroscopicsilicovolcanoconiosis succeeded electrophotomicrographically as the longest word in the English language.
