The Record Holder
The longest word in the Britannica Dictionary is Pneumonoultramicroscopicsilicovolcanoconiosis.
Quite a mouthful, isn’t it?
This term refers to a specific type of lung disease caused by the habitual inhalation of very fine silicate or quartz dust.
Origin of Pneumonoultramicroscopicsilicovolcanoconiosis
The term Pneumonoultramicroscopicsilicovolcanoconiosis was first coined in 1935 by Everett M. Smith, the president of the National Puzzlers’ League.
It was created as an intentionally long and complex term to serve as an example of how language can be stretched to its limits.
The word is derived from several parts:
- Pneumono-: from ancient Greek (πνεύμων, pneúmōn) which means lungs.
- Ultra-: from Latin, meaning beyond.
- Microscopic-: from ancient Greek, meaning small looking, referring to the fineness of particulates.
- Silico-: related to silicon, a key component of the dust particles in question.
- Volcano-: points to the volcanic origin of the harmful dust particles.
- Coniosis: denotes a lung disease caused by the inhalation of dust or other organic material.
This term refers to a type of lung disease caused by the inhalation of very fine silicate or quartz dust particles, typically found in volcanic environments.
It’s also recognized as the longest word in the English language published in a popular dictionary, Oxford Dictionaries.
