To expand slightly the previous definitions, Pope (capitalized) is the title of the top leader in the Apostolic Roman Catholic churches, Coptic and Orthodox churches of Alexandria. Also named to popes them of the Russian Orthodox Church. It has several possible origins, it can come from latin papa (father) is the father of the Catholic Church, an acrostic Petri Apostoli Potestatem Accipiens ("the one who receives the authority of the Apostle Peter"), or Pedro Apóstol Pontífice Augusto, proposed in 1098 by urban II, after the Great Schism, or perhaps comes from the first two syllables of Pater Patratus. In any case, the problem appeared after the discovery of America, since in this continent the Christians knew a tuber called Daddy (with lower case), and could not carry to Europe an edible bulb with the same name of the Holy Father, so re He was baptized and in many countries it is known as potato. See also Pope, papar.
