Since the Vatican is a global institution, understanding it often
requires at least a passing familiarity with a few foreign languages.
Italian is a no-brainer, Latin still helps, and in the Pope Francis era,
Spanish gives you a leg up, too — especially Porteño, the brand of Spanish spoken in Francis’ native Buenos Aires.
Perhaps the most challenging language, however, is what one might call “Vaticanese,” referring to a frequently bewildering cluster of terms and phrases that have taken shape in and around the place, and often mean something only to insiders.
