The Indo-European language family descended from Proto-Indo-European, believed to have been spoken thousands of years ago. Indo-European languages are spoken throughout Europe, but particularly dominate Western Europe. Latin is usually classified as an Italic language of which the Romance languages are a subgroup. 2  It is extinct as a spoken language, but it is widely used as a liturgical language by the Roman Catholic Church and studied in many educational institutions.
