Spy movies and political thrillers often lean heavily on the use of code names, or “cryptonyms,” a term that developed from the combination of the Latin word “crypto” (“hidden”) and the combining form “-onym,” which designates a name. The Secret Service originally used cryptonyms to keep the movements of important figures confidential, and they still keep the tradition alive, but the code names are now public knowledge. Some notable former presidential cryptonyms include “Lancer” for President John F. Kennedy (a reference to Camelot and King Arthur’s court), “Deacon” for President Jimmy Carter (a reference to his commitment to the Christian faith), “Rawhide” for President Ronald Reagan (a nod to his past in Hollywood Westerns), and “Renegade” for President Obama. (The entire Obama family followed the tradition of receiving alliterative cryptonyms, with Michelle as “Renaissance,” Malia as “Radiance,” and Sasha as “Rosebud.”)
