Etymology

Origin of ambassador

First recorded in 1325–75; Middle English am-, embass(i)adour, imbassadore, from Anglo-French ambassateur, ambassaduer, from Italian ambassatore, dialectal Italian ambassadore, equivalent to ambass- stem of “to send a delegate” + -atore, -adore, from Latin -ātōrem accusative of -ātor noun-forming suffix; embassy, -ator

Explanation

An ambassador is an official representative for his or her country, stationed in another nation, like Benjamin Franklin, who was an ambassador to France. Ambassador usually describes the official diplomatic envoy who represents one country to another. These ambassadors work to promote understanding, perhaps by settling differences or clearing up misunderstanding. Used less formally, an ambassador can be anyone who represents something, like a pop singer who is a "brand ambassador" for a cosmetics company.
