Video #468: Pneumonoultramicroscopicsilicovolcanoconiosis
Series 5, Episode 36
Video Description:
This is a science video about "Pneumonoultramicroscopicsilicovolcanoconiosis".
"Pneumonoultramicroscopicsilicovolcanoconiosis" is a 45-letter scientific word which is defined as the inhalation of silica dust, which causes inflammation in the lungs. It is also considered to be one of the longest words in English language, but it is actually the longest word published in dictionaries.
I first heard about this word since November 2012, and I was amazed by this 45-letter word still as of today.
