[1] It was named after its discoverer, Hrachia Acharian, whose surname was also romanised in a Western Armenian form as Adjarian.
Compare:[2] as opposed to absence of vowel fronting after the non-aspirated voiced stops: This conditioning is not a synchronic process, but rather reflects the quality of the original prevocalic consonant.
Garrett interprets this to mean that Adjarian's law should be considered a type of transphonologization, where breathiness leads to [+ATR] only if it is simultaneously lost.
[7] Adjarian's law demonstrates that the Proto-Armenian language retained the PIE aspirated stops and had not undergone a Germanic-style consonant shift.
Since voiced aspirates then have to be reconstructed for Proto-Armenian, only Germanic can be claimed to be "archaic" for PIE consonantism in the glottalic theory framework.
