legate (lĕgˈət) [key] [Lat. legare = to send], one sent as a representative of a state or of some high authority. In Roman history a legate was sent by the senate to the provinces as an envoy of the emperor. Sometime during the 12th cent. the word came into use to designate a papal ambassador. There are various types of papal legate, including the legatus a latere, a cardinal commissioned for a special confidential assignment as a representative of the pope; the nuncio or internuncio, who represents the Holy See, both temporally and ecclesiastically, in countries that exchange ambassadors with the Vatican (see nuncio, apostolic); and the apostolic delegate, a papal representative in a country that does not exchange ambassadors with the Vatican.
