ヒッタイト語
According to some scholars, there is evidence of language borrowings (Armenisms) from the [[Proto-Armenian]] language into [[Hittite language|Hittite ]] and [[Urartian language|Urartian]], what would prove the presence of Proto-Armenians in the Armenian Highlands, in the lands of [[ancient Armenia]], since at least the end of the 2nd millennium BC.
