Did You Know?

Miasma entered English from New Latin in the mid-1600s and comes ultimately from the Greek miainein, meaning "to pollute." In notes taken during a voyage to South America on the HMS Beagle in the 1830s, Charles Darwin described an illness that he believed was caused by "miasma" emanating from stagnant pools of water. For him, miasma meant an invisible emanation of "infecting substances floating in the air … considered to be noxious to health," as defined in Noah Webster's 1828 An American Dictionary of the English Language. Nowadays, we know germs are the source of infection, so we aren't likely to use the unscientific miasma this way. But while Darwin was out to sea, broader applications of miasma were just starting to spread. Now the term is used for something destructive or demoralizing that surrounds or permeates.
