Any language, explain what it means if it’s not English.
For example (as a non-native speaker) I’ve always liked the English word ‘unprecedented’, mostly in the context of fiction. Especially if it paints some entity to be really mystical or wondrous or it’s own never before seen order of magnitude in any way.
i feel the same way about pneumonoultramicroscopicsyllacovolcanoconiosis. it’s fun to say!
it’s not considered a real word anymore (and from what i gather, never really was a real word, in the opinion of the english nerds who decide such things) but i learned how to say it, dammit! i can’t unlearn that!
i might have even learned how to spell it correctly. i didn’t check the spelling as i wrote it in this comment but i also don’t think it matters if i incorrectly spell a word that isn’t really a word. so… yeah…
anyways, it was possibly used as a complicated version of what was known as ‘black lung’ disease, which coal miners in the appalacians contracted from inhaling silica dusts, for anyone curious.
It should be “silico” instead of “syllaco”. It comes from “silicon”, like the dust you mentioned.
