the eastern empire adopted which language in replacement of latin
Languages of the Roman Empire In the Eastern empire, laws and official documents were regularly translated into Greek from Latin.[44] Both languages were in active use by government officials and the Church during the 5th century.[45] From the 6th century, Greek culture was studied in the West almost exclusively through Latin translation.[46] Latin loanwords appear liberally in Greek texts on technical topics from late antiquity and the Byzantine period.[47]
