code names

A code name or cryptonym is a word or name used, sometimes clandestinely, to refer to another name, word, project or person. Code names are often used for military purposes, or in espionage. They may also be used in industry to protect secret projects and the like from business rivals, or to give names to projects whose marketing name has not yet been determined. Another reason for the use of code names and code phrases in the military is that they transmit with a lower level of cumulative errors over a walkie-talkie or radio link than actual names.
