The term "Hellenistic Dialects" refers to the various forms of the Greek language that emerged during the Hellenistic period, which lasted from the death of Alexander the Great in 323 BCE to the rise of the Roman Empire. This era saw the spread of Greek culture and language across a vast region, leading to the development of regional dialects influenced by local languages and cultures. Among the most notable Hellenistic dialects is Koine Greek, which became the lingua franca of the eastern Mediterranean and the Near East. Koine Greek simplified many features of earlier dialects, making it more accessible for communication among diverse populations. It played a crucial role in the spread of Christianity and the translation of texts, including the Septuagint.
