Greek is an Indo-European language, the sole surviving descendant of the Hellenic sub-family. Although it split off from other Indo-European languages before 2000 BC, it is first attested in the Bronze Age as Mycenaean Greek. During the Archaic and Classical eras, Greek speakers wrote numerous texts in a variety of dialects known collectively as Ancient Greek. In the Hellenistic era, these dialects underwent dialect levelling to form Koine Greek which was used as a lingua franca throughout the eastern Roman Empire, and later grew into Medieval Greek. For much of the period of Modern Greek, the language existed in a situation of diglossia, where speakers would switch between informal varieties known as Dimotiki and a formal one known as Katharevousa. Present-day Modern Standard Greek is largely an outgrowth of Dimotiki, with some features retained from Katharevousa.
