Koine Greek
Koine Greek remained the dominant language in the eastern part of the Roman Empire, extending into the Byzantine Empire as Byzantine Greek. In the city of Rome, Koine Greek was in widespread use among ordinary people, and the elite spoke and wrote Greek as fluently as Latin. Jewish Koine Greek did not exist as a separate dialect, but some Jewish texts in Koine Greek do show the influence of Aramaic in syntax and the influence of Biblical background in vocabulary.
