Hello there!
Let's go back when I'm a high
school student. I was grade 10 that time when my science teacher asked all of
us (grade 10-Loyalty) to spell the "Pneumonoultramicroscopicsilicovolcanoconiosis"
so we don’t have any idea what is the spelling and meaning of that word.
Then, when my teacher pronounce it, it is easy to spell. It’s one of the
longest word in science. The meaning of "Pneumonoultramicroscopicsilicovolcanoconiosis"
: “a pneumoconiosis caused by
inhalation of very fine silicate or quartz dust.” “to mean a lung disease caused by inhaling very fine ash and
sand dust.” : “Silicosis” is
a form of occupational lung disease caused by inhalation of crystalline silica
dust, and is marked by inflammation and scarring in the form of nodular lesions
in the upper lobes of the lungs. It is a type of pneumoconiosis. So, that's what I've learned in my science subject.
