Papabile (Italian pronunciation: [paˈpaːbile], pl. papabili) is an unofficial Italian term first coined by Vaticanologists and now used internationally in many languages to describe a Roman Catholic man, in practice always a cardinal, who is thought a likely or possible candidate to be elected pope. A literal English translation would be "pop(e)able" or "able to be pope". In Italy the term has become very common and people use it for other situations too.
In some cases the cardinals will choose a papabile candidate. Among the papabili cardinals who have been elected pope are Eugenio Pacelli (Pius XII), Giovanni Battista Montini (Paul VI), and Joseph Ratzinger (Benedict XVI). However, at times the College of Cardinals elect a man who was not considered papabile by most Vatican watchers. In recent years those who were elected pope though not considered papabile include John XXIII, John Paul I, and John Paul II. There is a saying among Vaticanologists: "He who enters the conclave as pope, leaves it as a cardinal." This is a popular proverb in Italy as well, especially used among the elderly.
The list of papabili changes as cardinals age. For instance, Carlo Maria Martini was thought to be papabile until he retired from his see upon reaching 75 years of age.
In Italian, the word papabile is also used in non-Church contexts referring to short list candidates, i.e. those who, among the available candidates, are most likely to get elected or appointed to a specific position.
Being seen as papabile, however, is no guarantee of election, and is sometimes seen as a handicap. (It should be noted that while the following candidates were widely discussed as candidates publicly, the actual vote results described below are frequently based on rumours and sourced, if at all, from off-the-record reports of individual cardinals.)
