what was the official language of the byzantine empire?\nlatin\ngreek\nfrench\nitalian

Brief Explanations:

The Byzantine Empire, which was the continuation of the Roman Empire in the East, gradually shifted its official language. Initially, Latin was used, but over time, Greek became more prominent. Greek had a long - standing cultural presence in the Eastern Mediterranean. By the later periods of the Byzantine Empire, Greek was the de facto and then the official language. It was used in administration, the church (Byzantine Christianity), and in intellectual and literary works. Latin was still used in some official contexts in the early days but was phased out as Greek took over. French and Italian were not languages of the Byzantine Empire's officialdom. French was a language that developed in Western Europe after the fall of the Western Roman Empire, and Italy, while part of the Roman Empire, was not the center of the Byzantine (Eastern Roman) administrative and cultural identity which was more rooted in the Greek - speaking East.
