The longest word in the English dictionary
While the above-mentioned monster is the longest word in English, it’s debatable whether it’s even a word, which is why it’s not listed in any English dictionary. In that case, what’s the longest word in the English language dictionary? It’s pneumonoultramicroscopicsilicovolcanoconiosis.
The irony is that pneumonoultramicroscopicsilicovolcanoconiosis isn’t even a real word! It’s a term invented by Everett M. Smith, president of the National Puzzlers’ League. Everett coined this term as a sarcastic term for long medical terms as well as a synonym for silicosis, a lung disease caused by inhaling sand and ash dust.
Pneumonoultramicroscopicsilicovolcanoconiosis is a collection of Latin terms that describe an inflammatory lung disease caused by long-term silica dust inhalation. While the term is made up, the disease is real and is known in the United Kingdom as pneumoconiosis, silicosis, or black lung.
Let’s dissect this longest word in English to make you understand its pronunciation.
