The word "envoy" means a person who is sent as a representative on a special mission, typically by a government or organization, to another government or organization. An envoy usually acts as a messenger or delegate carrying important communications or negotiations and often helps maintain diplomatic or official relations. The term is mostly used in formal contexts such as diplomacy, politics, or negotiations. It can also refer to a brief postscript in poetry or a farewell poem, but the primary meaning is a diplomatic or official representative sent on behalf of another entity.
