Graeco-Albanian
The term Graeco-Albanian refers to a theoretical division within the broader linguistic family known as Paleo-Balkanic. This division was theorized by linguists Brian D. Joseph and Adam Hyllested, it includes the "Illyric" languages, encompassing Albanian and Messapic, as well as the Graeco-Phrygian languages, which consist of Greek and Phrygian. Among these, the only languages to have survived are Albanian and Modern Greek.
