The presence of a population who spoke Proto-Armenian in Urartu prior to its demise is subject to speculation, but the existence of Urartian words in the Armenian language and Armenian loanwords into Urartian suggests early contact between the two languages and long periods of bilingualism. The presence of toponyms, tribal names, and deities of probable Proto-Armenian etymologies which are attested in records left by Urartian kings, such as Uelikuni, Uduri-Etiuni, Abiliani, and Arzashkun, the personal names Arame and Diaṣuni, and the deities Arṣibedini and Aniqu, further supports the presence of an Armenian speaking population in at least the northern regions of Urartu. Until recently, it was generally assumed that Proto-Armenian speakers entered Anatolia around 1200 BC, during the Bronze Age Collapse, which was three to four centuries before the emergence of the Kingdom of Van. However, recent genetic research suggests that the Armenian ethnogenesis was completed by 1200 BC, making the arrival of an Armenian-speaking population as late as the Bronze Age Collapse unlikely.[102] Regardless, the Urartian confederation united the disparate peoples of the highlands, which began a process of intermingling of the peoples and cultures (probably including Armenian tribes) and languages (probably including Proto-Armenian) within the highlands. This intermixing would ultimately culminate in the emergence of the Armenian language as the dominant language within the region.

A theory, supported by the official historiography of Armenia and experts in Assyrian and Urartian studies such as Igor M. Diakonoff, Giorgi Melikishvili, Mikhail Nikolsky, and Ivan Mestchaninov, suggests that Urartian was solely the formal written language of the state, while its inhabitants, including the royal family, spoke Proto-Armenian. This theory primarily hinges on the fact that the Urartian language used in the cuneiform inscriptions were very repetitive and scant in vocabulary (having as little as 350–400 roots). Furthermore, over 250 years of usage, it shows no development, which is taken to indicate that the language had ceased to be spoken before the time of the inscriptions or was used only for official purposes.[better source needed]

A complementary theory, suggested by Tamaz V. Gamkrelidze and Ivanov in 1984, places the Proto-Indo-European homeland (the location where Indo-European would have emerged from) in the Armenian Highlands, which would entail the presence of proto-Armenians in the area during the entire lifetime of the Urartian state.[103] Although this theory has less support than the more popular Kurgan hypothesis, the Armenian hypothesis would support the theory that the Urartian language was not spoken, but simply written, and postulates that the Armenian language was an in situ development of a 3rd millennium BC Proto-Indo-European language
