Graeco-Armenian (also Helleno-Armenian) is the hypothetical common ancestor of the Greek and Armenian languages that postdates the Proto-Indo-European language (PIE). Its status is comparable to that of the Italo-Celtic grouping: each is widely considered plausible without being accepted as established communis opinio.
The hypothetical Proto-Graeco-Armenian stage would need to date to the 3rd millennium BC, only barely differentiated from either late PIE or Graeco-Armeno-Aryan.
The hypothesis originates with Pedersen (1924), who noted that the number of Greek-Armenian lexical cognates is greater than that of agreements between Armenian and any other Indo-European language. Meillet (1925, 1927) further investigated morphological and phonological agreement, postulating that the parent languages of Greek and Armenian were dialects in immediate geographical proximity in the parent language. Meillet's hypothesis became popular in the wake of his Esquisse d'une grammaire comparée de l'arménien classique (1936). Solta (1960) does not go as far as postulating a Proto-Graeco-Armenian stage, but he concludes that considering both the lexicon and morphology, Greek is clearly the dialect most closely related to Armenian. Hamp (1976:91) supports the Graeco-Armenian thesis, anticipating even a time "when we should speak of Helleno-Armenian" (meaning the postulate of a Graeco-Armenian proto-language). Clackson (1994:202) is again more reserved, holding the evidence in favour of a positive Graeco-Armenian sub-group to be inconclusive and tends to include Armenian into a larger Graeco-Armeno-Aryan family.
Evaluation of the hypothesis is tied up with the analysis of the poorly attested Phrygian language. While Greek is attested from very early times, allowing a secure reconstruction of a Proto-Greek language dating to the late 3rd millennium, the history of Armenian is opaque. It is strongly linked with Indo-Iranian languages; in particular, it is a Satem language.
The earliest testimony of the Armenian language dates to the 5th century AD (the Bible translation of Mesrob Mashtots). The earlier history of the language is unclear and the subject of much speculation. It is clear that Armenian is an Indo-European language, but its development is opaque. In any case, Armenian has many layers of loanwords and shows traces of long language contact with Greek and Indo-Iranian. Nakhleh, Warnow, Ringe, and Evans (2005) compared various phylogeny methods and found that five procedures (maximum parsimony, weighted and unweighted maximum compatibility, neighbor joining, and the widely criticized technique of Gray and Atkinson) support a Graeco-Armenian subgroup.
||There is a proposal that this section be split into a new article titled Balkan Indo-European. (Discuss) (April 2014)|
An interrelated problem is whether there is a "Balkan Indo-European" subgroup of Indo-European, which would comprise not only Greek and Armenian, but also Albanian and possibly some dead languages on the Balkans. This theory has been argued for in various publications by scholars such as G. Neumann, G. Klingenschmitt, J. Matzinger, J. H. Holst. This Balkan subgroup in turn is supported by the lexicostatistical method of H. J. Holm.
