Did you know?

"This little happiness is so very precarious, that it wholly depends on the will of others." Joseph Addison, in a 1711 issue of Spectator magazine, couldn't have described the oldest sense of precarious more precisely—the original meaning of the word was "depending on the will or pleasure of another." Precarious comes from a Latin word meaning "obtained by entreaty," which itself is from the word for prayer, prex.
