Koine Greek grammar is a subclass of Ancient Greek grammar peculiar to the Koine Greek dialect. It includes many forms of Hellenistic era Greek, and authors such as Plutarch and Lucian,[1] as well as many of the surviving inscriptions and papyri.
Koine texts from the background of Jewish culture and religion have distinct features not found in classically rooted writings. These texts include the Septuagint (Greek Old Testament, which includes the Deuterocanonical books), New Testament, Josephus, Philo of Alexandria, the Greek Old Testament Pseudepigrapha, and early Patristic writings.
