Latin is a member of the Romance branch of the Indo-European language group. Originally, it was spoken in Latium, Italy. Vulgar Latin developed into Romance languages such as French, Spanish and Romanian.
Latin is still the official language of Vatican City and is used in documents in the Roman Catholic Church. The Vatican even has a cash machine that lists instructions in Latin.
Despite being thought of as a dead language, Latin appears to be doing quite well – the Latin version of Wikipedia contains more than 100 000 articles.
