Code word (figure of speech) A code word is a word or a phrase designed to convey a predetermined meaning to a receptive audience, while remaining inconspicuous to the uninitiated. For example, a public address system may be used to make an announcement asking for Inspector Sands to attend a particular area, which staff will recognise as a code word for an fire or bomb threat, and the general public will ignore.
Codenames has an espionage setting, in which players in teams try to identify their own team's secret agents, based on their agents' code names. Codenames is a game of guessing which code names (words) in a set are related to a hint-word given by another player. Players split into two teams, red and blue. One player of each team is selected as the team's spymaster; the others are field operatives.
