secret message
Encoded private note
A secret message is communication intended only for specific recipients, hidden from others through codes, ciphers, invisible ink, or concealment.
Children pass secret messages in class; spies transmit them across borders.
The phrase also applies to perceived hidden meanings: Critics found a secret message in the film's ending.
