A secret word or phrase used as a signal between people to identify each other or to communicate secretly without revealing the real message.
From 'code' (a system of symbols) and 'word,' combining in the 20th century as espionage and secret communication became more common. Used especially in military and intelligence contexts.
Spies use codewords like 'the eagle has landed' to communicate without revealing plans if someone overhears—each word masks the real meaning to only those who know the code!
