Etymology

Popularized in contemporary usage by U.S. President Richard Nixon in a speech on November 3, 1969. The older sense for "the dead" was used in English since the 19th century, and further back in Latin by the Roman writer Petronius, who wrote abiit ad plures (“he has gone to the majority”) to describe the dead.
