(PMF) is a lung disease caused by the inhalation of very fine silica dust particles. It is a form of pneumoconiosis, which is a type of lung disease caused by inhaling dust particles. Symptoms of PMF include coughing, shortness of breath, chest pain, and difficulty breathing. Long-term exposure to silica dust can cause scarring of the lungs, which can lead to serious health problems and even death.

Pneumoultramicroscopicsilicovulcanoconiotic (/ˌnjyoumənoʊˌʌItrəˌmaɪkrəˈskɒPɪkˌsɪIɪkoʊvɒIˌkeɪnoʊˌkoʊnIˈoʊsɪs/ (I hear)) is a made-up word coined in 1935 by the then president of the National League of Puzzles, Everett M. Smith. It has sometimes been used as a synonym for the occupational disease known as silicosis, but it shouldn’t be, as most silicosis is unrelated to volcanic dust mining, and no evidence of silicosis has been found in populations exposed to crystalline silica in volcanic ash. It’s the longest word in the english language published in a dictionary, oxford dictionarieswhich defines it as “an artificial long word signifying a lung disease caused by inhaling very fine volcanic dust”.
Clinical and toxicological research carried out on volcanic crystalline silica has found little or no evidence of its ability to cause silicosis/pneumoconiosis-type diseases and geochemical analyzes have shown that there are inherent factors in the crystalline structure that may make volcanic crystalline silica much less pathogenic than some other forms of crystalline silica.
Silicosis is a form of occupational lung disease caused by inhaling crystalline silica dust and is marked by inflammation and scarring in the form of nodular lesions in the upper lobes of the lungs. It’s a kind of pneumoconiosis and is known in the UK as the black lung.
Pneumonoultramicroscopicsilicumovulcanoconiosis is the longest word in the English language. The word can be parsed like this:
- pneumonia: from ancient Greek (pneumonia) which means lungs
- ultra: from Latin, meaning beyond
- micro and scopic: from ancient Greek, meaning small appearance, referring to the fineness of the particles
- silico-: from Latin, silicon
- volcano: from Latin, referring to the volcano
- coni: from ancient Greek (konis) which means dust
- -osis: from ancient Greek, suffix to indicate a medical condition
This word was invented in the daily meeting of the National League of Puzzles (NPL) by its President Everett M. Smith. The highlighted word in the headline of an article published by New York Herald Tribune on February 23, 1935, titled “Puzzlers Open 103rd Session Here by Recognizing 45-Letter Word”:
“Pneumonoultramicroscopicsilicovolcanoconiosis achieved electrophotomicrographically the longest word in the English language recognized by the National Puzzlers’ League in the opening session of the organization’s 103rd Semiannual Meeting held yesterday at the Hotel New Yorker. The puzzles explained that the forty-five-letter word is synonymous in a special way of pneumoconiosis caused by ultramicroscopic silica particles volcanic dust…”—As quoted from New York Herald Tribune in reference
It should be noted, however, that despite defining it as synonymous with pneumoconiosis, there is no scientific evidence of a similar disease related to exposure to volcanic particles.
Later, the word was used in Frank Scullypuzzle book bedside mannaafter which NPL members campaigned to include the word in major dictionaries.
This 45-letter word, known as “P45”, first appeared in the 1939 supplement of the Merriam Webster New International Dictionary, Second Edition.
Any internet reference to pneumonoultramicroscopicsilicovulcanoconiosis or silicosis caused by ‘sharp particles [which] torn lining of the lungs; causing the victim to leak air from their lungs while simultaneously bleeding into their lung cavity’ are inaccurate. Particles of a size capable of entering the lung (< 10 µm in diameter) settle smoothly into the lining of the lung rather than cutting or abrading the surface.
