It is unclear whether Balkan languages formed at some point a genetic unity, or different Yamna communities just settled in neighbouring regions in the Balkans. Nevertheless, it seems common ground to speak about an ancestral Graeco-Armenian community, which split into Armenian and Graeco-Phrygian, which in turn split into Graeco-Macedonian and Phrygian.
Common features of Palaeo-Balkan languages include (Hajnal 2003):
· Vocalisation of word-initial laryngeals before consonants.
· Retention of the original restriction of initial *r-, as found in Anatolian[xiii].
· Relatively systematic vocalisation of LPIE *-iħ as *-i̯ă (Albanian less clear, although cf. zonjë ‘lady’ from *desi̯ās-potni̯ă), in contrast with the more widespread *-ī alternative.
· Formation of identity adjectives and patronymics in *-eii̯o-.
· Spread of locative plural in *-si, in contrast with the alternative *-su.
· Relevance of sigmatic preterite(-aorist?) formations.
· Outcome of 3p.sg. in *-(e)s < *(e)st, and plural *-(e)san < *(e)s-n̥t (pointing to a loss of final consonant).
Lexical correspondences include (Martirosyan 2013):
· *an(e/ō)rio- ‘dream’ cf. Arm. anurǰ-kՙ, Gk. anar- onar-, Alb. adërrë <*andërrë.
· *bhe/or-(e)n- ‘load (“that is borne”), freight’, cf. Arm. bern, Gk. phernḗ, Alb. bárrë. Probably a European isogloss retaining the original meaning; compare for a cognate with shift in meaning NWIE *bhornā- ‘child, baby’ in Goth. and ON barn, Lith. bérnas.
· *sk(h)odoro- or *sk(h)orodo- ‘garlic’, cf. Arm. xstor, sxtor, Gk. skór(o)don, Alb. húrdhë, also húdhër.
Common features of Graeco-Armenian include:
· Trend to devoicing of voiced stops (with further developments in the different branches).
· Development of *s → *h (also in Phrygian), although it may have been due to parallel developments.
· e-augment: a Graeco-Aryan feature that was kept or expanded in Greek, Phrygian, and Armenian.
· Formation of specific verbs in *-nu- restricted to these dialects.
· Productive -n-presents beside root aorists (also present in Indo-Iranian and Tocharian).
· Instrumental singular in *-bhi; locative (singular) Arm. -oǰ ~ Gk. -othi.
· Innovative inflectional class in -olā-.
· Verbal suffix *-sk- in forms restricted to past time.
· Certain verbal reduplications not found in other branches.
