#### Usage notes

* This word was invented purely to be a contender for the title of the longest word in the English language, comprising forty-five letters and nineteen syllables. The word is not in official medical usage, and textbooks refer to this disease as pneumonoconiosis, pneumoconiosis, or silicosis.
* Cited as the longest word in the Oxford English Dictionary, the dictionary lists it as “a factitious word alleged to mean ‘a lung disease caused by inhalation of very fine silica dust usually found in volcanos’ but occurring chiefly as an instance of a very long word”.
