Graeco-Armenian

Graeco-Armenian (or Helleno-Armenian) is the hypothetical common ancestor of Greek (or Hellenic) and Armenian branches that postdates the Proto-Indo-European language. Its status is somewhat similar to that of the Italo-Celtic grouping: each is widely considered plausible without being generally accepted. The hypothetical Proto-Graeco-Armenian stage would need to date to the 3rd millennium BC and would be only barely different from either late Proto-Indo-European or Graeco-Armeno-Aryan.
