Graeco-Phrygian

Graeco-Phrygian (/ˌɡriːkoʊˈfrɪdʒiən/) 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. Furthermore, out of 36 isoglosses collected by Obrador Cursach, Phrygian shared 34 with Greek, with 22 being exclusive between them. The last 50 years of Phrygian scholarship developed a hypothesis that proposes a proto-Graeco-Phrygian stage out of which Greek and Phrygian originated, and if Phrygian was more sufficiently attested, that stage could perhaps be reconstructed.
