The Hellenic branch is one of nine still extent of the Indo-European languages; its principal member is Greek. It is speculated that some other languages spoken in ancient times, like Macedonian and Phrygian, may also have belonged to this family, but not enough documentary evidence survives to tell. In modern times, a number of languages exist that have descended from Ancient Greek, but are no longer mutually intelligible with Standard Modern Greek. Most notable among these is Tsakonian, the last known descendent of the Doric dialect of Ancient Greek. Others, more closely related to Standard Modern Greek but still not mutually intelligible, include Pontic, Cappadocian and Italiot.
