query: What language was spoken by the Roman Empire?
passage: Languages of the Roman Empire
Latin and Greek were the official languages of the Roman Empire, but other languages were important regionally. Latin was the original language of the Romans and remained the language of imperial administration, legislation, and the military throughout the classical period.[2] In the West it became the lingua franca and came to be used for even local administration of the cities including the law courts.[3][4] After all freeborn inhabitants of the Empire were universally enfranchised in 212 AD, a great number of Roman citizens would have lacked Latin, though they were expected to acquire at least a token knowledge, and Latin remained a marker of "Romanness".[5]
passage: Legacy of the Roman Empire
Latin was the lingua franca of the early Roman Empire and later the Western Roman Empire, while particularly in the East indigenous languages such as Greek and to a lesser degree Egyptian and Aramaic language continued to be in use. Despite the decline of the Western Roman Empire, the Latin language continued to flourish in the very different social and economic environment of the Middle Ages, not least because it became the official language of the Roman Catholic Church. Koine Greek, which served as a lingua franca in the Eastern Empire, is still used today as a sacred language in some Eastern Orthodox churches.
