Here is a Cultural Literacy worksheet on the term czar. This noun, of course, describes the absolute rulers of Russia (and, incidentally, like the German Kaiser, originates in ancient Rome with the Latin Caesar). But it also has been used, as the reading on this document explains, to describe public officials with wide-ranging powers. For example, the conservative writer and political activist William Bennett served as the director of the Office of National National Drug Policy under President George H.W. Bush, in which capacity he was known as the “Drug Czar.”
