Latin is as popular as English today: it was the official language of international communication and academia until the 18th century. Currently, the Catholic Church still uses Latin as the official language. Many schools around the world teach Latin as a compulsory module.
Latin today is considered a suicide (dead language). Learning English, you can talk to Americans and Australians. But learning Latin, you can’t talk to anyone: the only community that still uses Latin is the Catholic Church, but even in the church, most priests can read and not speak this language. Not to mention that the Church uses Ecclesiastical Latin , while scholars consider Classical Latin to be the standard version, especially in terms of pronunciation.
