What is the meaning of pneumonoultramicroscopicsilicovolcanoconiosis. ?
Its the longest word in English and its a lung disease
The longest word in English has 189,819 letters and would take you three and a half hours to pronounce correctly. Seriously. It's the chemical name of Titin (or connectin), a giant protein "that functions as a molecular spring which is responsible for the passive elasticity of muscle."
It is a lung disease caused due to the inhalation of fine silicate particles released in the air by the eruption of a volcano.
