Bergoglio is a proper noun, most notably the surname of Cardinal Jorge Mario Bergoglio, now Pope Francis. In Spanish and Italian-influenced usage, it denotes a family name pronounced with emphasis on the second syllable, and with a final vowel that remains open. It functions as a personal name and title, used in formal and journalistic contexts when referring to the pope or the individual. It is not a common English noun beyond this context.
