Official representatives or messengers sent on a special mission, especially on behalf of a government or leader.
From Latin 'emissarius' (sent out), from 'emittere' (to send forth). The word carries the idea of someone dispatched with authority to carry out diplomatic or secret missions.
The word 'emissary' is related to 'emit' and 'missile'—all about sending something out with purpose. In spy fiction, emissaries are often the cool characters doing secret negotiations!
