Koine Greek is a common dialect of the Greek language that emerged after the conquests of Alexander the Great in the 4th century BCE, serving as a lingua franca across much of the eastern Mediterranean and the Near East. This form of Greek was characterized by its simplified grammar and vocabulary, making it more accessible to people from diverse linguistic backgrounds, thus facilitating trade, cultural exchange, and communication in Hellenistic society, particularly during the Ptolemaic period in Egypt.
