#envoy

• Ablegate — A person sent as a delegate, emissary, or official representative on a mission; specifically, a papal representative of secondary rank (subdelegate) sent by the Holy See with special assignments. As an adjective, it qualifies an official or a status that has been sent, delegated, or removed through a formal administrative ruling.
• Ablegation (mission) — A rare conceptual form or terminological variant of 'ablegare'; the official mission entrusted to an emissary or the body of delegates sent to represent an authority. In certain early modern administrative sources, the word denoted both the official document granting legal and symbolic power to a delegate to act on behalf of the state.
• Ambassador — A diplomatic agent of the highest rank sent by a state as its permanent, extraordinary, and plenipotentiary representative to another sovereign head of state or international organization. Figuratively, a person, product, or entity that promotes or defends the values and prestige of a country or brand.
• Apocrisiarius — An old phonetic or spelling variant found in Byzantine manuscripts and medieval Romanian legal codes for the term 'apocrisiar' (apocrisiarius). It denotes a legate, emissary, special envoy, or official diplomatic representative of a patriarch, pope, or Byzantine emperor, sent to a foreign court or another ecclesiastical see to deliver official messages or negotiate dogmatic and territorial treaties.
• Public crier — An extremely rare archaic or regional term historically used in old charters or border dialects to designate a herald, a military envoy, or an official messenger tasked with reading aloud (delivering/reading out loud) princely commands or administrative decrees in public squares or army camps. In an institutional-structural sense, the aread ensured the transmission of strategic and legal information to the community in an era devoid of mass communication tools.
