This is not like Tibetan (Lhasa). In Tibetan, the front "ah" (referring to people) basically means nobler than oneself, but it means lake, so it is impossible to connect these two words, and the back "Naga" is nothing like Tibetan. It is better to have this Tibetan map or a more accurate pronunciation. I only analyze it from Uzan dialect. If it is Kangba dialect, I can't understand it.
