An envoy is a person sent as a representative on a special mission, typically in diplomatic or official contexts. They act as messengers carrying important communications between governments or organizations and often play crucial roles in maintaining peaceful relationships, negotiating terms, and representing the interests of one party to another. The term comes from the French word "envoy," meaning someone who is sent on a journey, and it can also denote a diplomatic rank below ambassador. In poetry, an envoy (or envoi) is a short stanza at the end of a poem that addresses the reader or comments on the poem.
