Technically speaking, pneumonoultramicroscopicsilicovolcanoconiosis is not a real word, but a fusion of multiple Latin terms. It is a synonym of silicosis. Silicosis is an interstitial lung disease caused by breathing in tiny bits of silica, a common mineral found in many types of rock and soil. Over time, exposure to silica particles causes permanent lung scarring, called pulmonary fibrosis… that’s got to hurt.
