A person sent as a messenger or representative to deliver a message or conduct business for someone else, usually someone powerful.
From Latin 'emissarius' meaning one sent out, derived from 'emittere' (to send out). The 'e-' means out and 'mittere' means to send. The word has been used in diplomacy and politics for centuries.
Throughout history, emissaries have been key to preventing wars—during the Cuban Missile Crisis, secret emissaries carried messages between Kennedy and Khrushchev to negotiate and prevent nuclear catastrophe!
