As you know I myself believe Iran/Armenia is the original land of Indo-Europeans, so it is certainly possible that many names/places in this region have IE origin but I'm talking the descendants of these IE people in this region, for example if you believe Armenian-speaking people lived there, you should mention some Armenian words in other languages, like Old Akkadian or Sumerian. I have asked the same thing from those who claim Iran is the original land of Iranian-speaking people or Turkey is the original land of Turkic people. Sumerian or Akkadian words in Persian or Turkish can't prove this thing, they just came to this land and adopted these words.
I don't necessarily believe that they were Armenian-speaking, as we know it today. But rather PPIE. I think that Armenian (as we know it) might have some elements of the PPIE language which was spoken in the region (i.e. Armenian is either conservative in some way or came in contact with a conservative IE language that was spoken in the Armenia region).
But okay--I've already said that Sumerian "kur" (mountain; foreign land) could come from a pre-satemized version of "sar" (the Armenian word for mountain). Other ones--early Sumerian "gi-in"/ge-en" (female), Armenian "geen" (woman). Sumerian "gu-ur(u)" (crow), Armenian "agrrav" (crow). Sumerian "gu(r)" (to eat), Armenian "ger" (eat [imperative]). Sumerian "igi" (eye), Armenian "akn>achk" (eye). Sumerian "luh" (to wash), Armenian "luvanel" (to wash). Sumerian "si-si" (horse), Armenian "dzi" (horse). Sumerian "uru" (to cultivate), Armenian "arawr>aravr" (to cultivate). Sumerian "agar" (field), Armenian "agarak" (farm).
Arra-ti, which is one of the names etymologized as Indo-European by Damgaard, dating to ~2300 BCE. Arra-ti would mean something like "of the sun god". I actually do not believe that Ararat is a Semitic word that gave rise to Urartu (the Akkadian version of the name) and Ayrarat (the Armenian version of the name), but rather that the name was Ayrarat first...which literally means "people of the sun god, Ar/Ara". Urartu is another version with a similar meaning--Ar-astu. So it's not Semitic>Hurro-Urartian>Armenian but rather Armenian>Hurro-Urartian>Semitic. Aratta of the Sumerians would be the same as Ararat.
In one of those Petrosyan articles I shared with you, he etymologizes the Hurro-Urartian Uelikummi (serpent/dragon) as coming from an PIE root (wel--"to see/know" and also "to coil"). Petrosyan suggests that PIE "wel" became proto-Armenian "uel" (which was borrowed into Hurro-Urartian) which became "gel" (which we see in Georgian) and modern Armenian "gegh." The Urartians or Assyrians mentioned a people called Uelikulki on the shores of Lake Sevan. That region is now called "Gegharkunik" with the "Gegham" Mountains nearby. Petrosyan suggests that there was a tribe in this region called Uelik/Welik (Welik) which would translate to "the Wel people".
I suggest that you read some of the articles that I've shared with you, for example, the one I shared with you earlier today regarding Armenian loans into Hurro-Urartian.
There are probably others. There are a lot from the Urartian-era. I could find more, specifically ones related to gods, from earlier, if you want...like Hattian "Arinna" (name of the holy city of the sun goddess). Ar/Ara are sun-related/sun god words in Armenian.
All of the words I mention here have accepted PIE roots, which makes me think that they were loans from IE>Hattian/Hurro-Urartian/Sumerian/Semitic and not vice versa. Also, as you can see, in the case of languages like Akkadian, sometimes the Armenian word is closer to Sumerian than it is to the Akkadian version (i.e. Sum. agar, Arm. agarak, Akk. ugaaru; Sum. si-si, Arm. dzi, Akk. sisium--this word may have arrived via Hurrian "issi" but the root is still considered to be IE).
I also wonder if uru and arawr (both meaning "cultivate") are related to the sun somehow due to the inclusion of "ara". Sunlight=plants growing.
