Why “papabile” is a great word
Considered a likely or viable candidate for election as Pope, especially a cardinal during a conclave. Borrowed from Italian papabile, from papa ("pope", from Late Latin) + -abile ("-able"). Unlike "pontiff" (which names the incumbent) or the generic "candidate" (which applies to any office), "papabile" denotes a specific, rarefied state of potential measured in whispered conversations. It is the speculative weight of a scarlet zucchetto, the studied neutrality of a public utterance parsed for clues, the palpable stillness around a man who must show no ambition for the throne he is judged most fit to occupy—the quiet agony of being the heir to an eternal kingdom that may never call.
