Pneumonoultramicroscopicsilicovolcanoconiosis is a mouthful, but it surely’s really an actual phrase. It is the longest phrase within the English language, and it refers to a lung illness brought on by inhaling very tremendous silica mud, typically present in volcanoes.
The phrase was first coined by American doctor and creator Everett M. Smith in 1935. He created it as a method to show the boundaries of the English language and to point out how tough it may be to pronounce some phrases. Nevertheless, the phrase has since been adopted by the medical neighborhood and is now used to explain an actual medical situation.
