See the Sumerian List of Kings for a new discovery. One of the problems which exists in identifying the Sumerians with absolute certainty is that scholars allege that Sumerian is unrelated to any known language. Before we compare Sumerian to Indo-European on the basis of the very archaic Latvian, we want to look at ancient hydronymy, the names of rivers and bodies of water, which hold on to their names with great tenacity. A. Breidaks studied parallels between the Baltic languages and the ancient Balkan languages, and there are many hydronymic names around the Black Sea which appear to have a Baltic connection. Here are homophonic words, identical in both languages.
Homophonic words sound the same but have different meanings.
That two languages have similar homophones by chance is minimal. In the Sumerian DUN- below, that accounts for the different variants. What a word. We unravel it below using Latvian. Dot design like Sumerian Halaf ware.
