Graeco-Phrygian languages
Graeco-Phrygian () is a proposed subgroup of the Indo-European language family which comprises the Hellenic and Phrygian languages. Modern consensus views Greek as the closest relative of Phrygian, a position that is supported by Brixhe, Neumann, Matzinger, Woodhouse, Ligorio, Lubotsky, and Obrador-Cursach.
