Vatican cracks down on a traditionalist group by excommunicating its bishops

[dalton99a]

17. Italian is the working and administrative language of the Vatican.

Many languages are spoken within the state, as its inhabitants come from many countries. Italian is the lingua franca of the Vatican and replaced Latin as the official language of the Synod of Bishops in 2014.[2] The Holy See, the entity with authority over the state (yet legally distinct), uses Latin as its official language and Italian as its main working language in administrative and diplomatic affairs. French is also sometimes used as a diplomatic language. In the Swiss Guard, Swiss German is the language used for giving commands, but the individual guards take their oath of loyalty in their own languages: German, French, Italian or Romansh.

Since the state was established, the native languages of the popes have been Italian, Polish, German, Spanish, and English.

The official website of the Holy See is primarily in Italian, with versions in English, French, German, Portuguese and Spanish, and partial versions in Arabic, Chinese and Latin.[5] Some content is also available in many other languages, such as Albanian, Belarusian, Croatian, Czech, Dutch, Hebrew, Hungarian, Indonesian, Japanese, Korean, Lithuanian, Maltese, Polish, Russian, Slovak, Slovene, Swahili and Ukrainian.[6][7]

The Holy See's newspaper L'Osservatore Romano is published in Italian, English, French, German, Polish, Portuguese and Spanish.[8] The Vatican News website is available in many languages: Albanian, Amharic, Arabic, Armenian, Belarusian, Bulgarian, Chinese, Croatian, Czech, English, Esperanto, French, German, Italian, Japanese, Korean, Latvian, Lithuanian, Hindi, Hungarian, Kannada, Malayalam, Macedonian, Polish, Portuguese, Romanian, Russian, Slovak, Slovene, Spanish, Swahili, Swedish, Tamil, Tigrinya, Ukrainian, and Vietnamese.[9]
