Pneumonoultramicroscopicsilicovolcanoconiosis is a word that still continues to cause some controversy. It is one of the longest words in English language, but many people believe it was coined for the sole purpose of being a long word and beating the record of other long English words. However, the disease described by that long name is a real one.

About the word

Just reading or hearing this word, let alone trying to pronounce it, can lead people to think that pneumonoultramicroscopicsilicovolcanoconiosis is either a made up word or truly the longest one in English vocabulary. Neither of those is true. Pneumonoultramicroscopicsilicovolcanoconiosis is a real disease, and the word itself is not the longest English word. It is, however, the third longest word, according to most linguistic experts. It has 45 letters, while the longest and the second-longest English words have 189,819 and 183 letters respectively. The word was coined in 1935 by Everett M. Smith, who was the president of National Puzzler’s league.

The word pneumonoultramicroscopicsilicovolcanoconiosis combines elements from Greek and Latin language. Pneumo comes from Greek and refers to lungs, Ultra is Latin for beyond, Micro is Greek for small and scopic, also Greek, refers to looking. Silico in Latin indicates that something is sand-like, Volcano is, obviously, a volcano, Konis means dust in Greek and words ending in –osis, which is Greek, indicate a disease.

The correct way to pronounce this complicated word would be: NYOO-muh-noh-ul-truh-my-kruh-skop-ik-SIL-i-koh-vol-kay-noh-koh-nee-OH-siss.

About the disease

If one looks pneumonoultramicroscopicsilicovolcanoconiosis up in a dictionary, s/he will learn that it is a disease caused by overexposure to ultra-tiny silica dust. It is in fact very similar to silicosis.

This disease is considered to be a form of pneumoconiosis, a respiratory disease caused by inhalation of metallic dust or particles, only in pneumonoultramicroscopicsilicovolcanoconiosis what is inhaled is siliceous volcanic dust.

The disease exists in four types. Those include asymptomatic, accelerated, acute and chronic forms. Asymptomatic form of the disease does not show any symptoms, hence the name.

The symptoms, if and when they appear, include severe cough, sore throat, chest pain, fast breathing and loss of appetite.

If a person is exposed to siliceous volcanic dust for more than 10 years, the disease becomes chronic. It also increases the risk of tuberculosis.

The disease is, fortunately, easy to treat. It requires avoiding further exposure to siliceous dust and taking antibiotics. The important thing is to diagnose it, specifically to be able to determine than a person has, in fact, been exposed to quantities of dust sufficient enough to cause the disease.
