Definition of PLENIPOTENTIARY

Did You Know?

Adjective

The adjective plenipotentiary is typically used, as in our second example, after the noun it modifies in the ranking of diplomatic hierarchy. Plenipotentiary gets its power from its Latin roots: plenus, meaning "full," and potens, "powerful." When government leaders dispatch their ambassador plenipotentiary, minister plenipotentiary, or envoy plenipotentiary, they are not just sending an agent to deal with foreign affairs but one having full power to act on the behalf of his or her country and government. The word extraordinary is also found in titles of government representatives-sometimes in combination with plenipotentiary (as in "Ambassador Extraordinary and Plenipotentiary")-to denote an agent assigned to a particular (or extraordinary) diplomatic mission. Both the adjective and the noun plenipotentiary (meaning "a person invested with full power to transact business") appeared in the mid-17th century.
