is the conduct of negotiations
between persons, groups, or nations. Used formally, it refers to the conduct of international relations through the intercession of (usually) professional diplomats
Once concerned most prominently with royal dynastic marriage-alliances and questions of war and peace, diplomacy now concerns itself more with issues of trade and culture.
An ambassador is the most senior diplomatic rank. (See the list of ambassadors.)
In an informal or social sense, diplomacy often refers to the phrasing of statements in a tactful, non-confrontational, or social manner.
