Ersatz can be traced back in English to the 1870s, but it really came into prominence during World War I. Borrowed from German, where Ersatz is a noun meaning "substitute," the word was frequently applied as an adjective in English to modify terms like coffee (made from acorns) and flour (made from potatoes)—ersatz products resulting from the privations of war. By the time World War II came around, bringing with it a resurgence of the word along with more substitute products, ersatz was wholly entrenched in the language. Today, ersatz can be applied to almost anything that seems like an artificial imitation.
