Pneumonoultramicroscopicsilicovolcanoconiosis

From Wikipedia, a free encyclopedia written in simple English for easy reading.

Pneumonoultramicroscopicsilicovolcanoconiosis is a lung disease caused by the breathing-in of very small particles of sand or quartz dust found in volcanoes.

The origins of this forty-five-letter word have, however, been considered as a hoax. It was first seen in the Oxford English Dictionary in 1936.

The real name of this disease is the fourteen-letter pneumoconiosis.
