An envoy is a messenger or representative sent on an official mission, especially in diplomatic or government work. When two countries need to communicate about important matters, they might send envoys to deliver messages, negotiate agreements, or represent their nation's interests. Think of an envoy as a trusted go-between who carries the authority to speak for whoever sent them.

Historically, envoys traveled great distances to deliver crucial messages between rulers and nations. Before telephones or email, an envoy might spend months journeying to deliver a single important letter or to negotiate a treaty. The role required intelligence, diplomacy, and trustworthiness. Envoys had to remember exactly what they were told to say and represent their home country with skill and tact.

Modern nations still use envoys for sensitive diplomatic missions. A presidential envoy might travel to another country to discuss climate policy or trade agreements. The term can also be used more casually: you might serve as an envoy for your class if you're chosen to present a proposal to the principal, carrying your classmates' ideas and speaking on their behalf.
