i played this game when i had Pneumonoultramicroscopicsilicovolcanoconiosis which is a made up word coined in 1935 by the then president of the National Puzzlers' League, Everett M. Smith. It has sometimes been used as a synonym for the occupational disease known as silicosis, but it should not be as most silicosis is not related to mining of volcanic dusts, and no evidence of silicosis has been found in populations exposed to crystalline silica in volcanic ash. It is the longest word in the English language published in a dictionary, Oxford Dictionaries, which defines it as "an artificial long word said to mean a lung disease caused by inhaling very fine volcanic dust".[3]

Clinical and toxicological research conducted on volcanic crystalline silica has found little to no evidence of its ability to cause silicosis/pneumoconiosis-like diseases and geochemical anlayses have shown that there are inherent factors in the crystalline structure which may render volcanic crystalline silica much less pathogenic than some other forms of crystalline silica.[4][5]

Silicosis is a form of occupational lung disease caused by inhalation of crystalline silica dust, and is marked by inflammation and scarring in the form of nodular lesions in the upper lobes of the lungs. It is a type of pneumoconiosis and is known in the United Kingdom as black lung. anyways it was pretty fun
