The name Moash was originally a singer name... How?

[An Inkspren]

We learn that Moash was a singer name. How is this possible? As far as I can tell the first Parshendi contact was just a few years before Gavilar's assassination, way after Moash was born. So the only way for a Parshendi way to make it's way to Moash's name is either it was kept around for 4500 years or it's pure coincidence. What do you think?

I think it's something similar to the lighthouse keeper with his family history of watching the one direction. Strange things will survive the passage of time.

We know that there has been non-violent interaction between humans and singers for many years during the desolations, to the point that entire populations of Roshar are descended from human/singer unions. With so much cultural mixing, it's entirely possible that some aspects of the different cultures were picked up by the different races. "Moash" was probably just a name that had origins with the singers, but started to be used by humans some time before the Recreance, and continued to be used up to current day.

Heck, the Dawnchant was used as a lingua franca on Roshar for a long time, despite the fact most of the languages aren't actually directly descended from it (the main languages in the Dawnate family are Shin, listener, and Horneater, iirc), though they were all pretty majorly influenced. While it was often war, there was clearly a lot of cultural intermixing at various points, and some of the Heralds may even have names from the Dawnsingers' language (Kaladin's name is from one of the languages Brandon uses to indicate the word has Dawnchant roots, and in-world his name comes from Kalak's) .
