Did you know?
When English speakers hear "achoo," they usually respond with either "gesundheit" or "God bless you." Gesundheit was borrowed in the early 20th century from German, where it literally means "health"; it was formed from gesund ("healthy") and -heit ("-hood"). Wishing a person good health when they sneeze was historically believed to forestall the illness that a sneeze often portends. "God bless you" had a similar purpose, albeit with more divine weight to the well-wishing. Gesundheit at one time also served as a toast when drinking (much like its English counterpart, "to your health"), but this use is now largely obsolete.
