[Zone 5 & 6 Spoilers] I need the naming conventions

[KamiyaJace]

So, I think I figured out the naming conventions in most of Tural pretty easily and can follow the ideas behind naming for all of the groups (Hhetsarro, Xbr'aal, Shentona, Tonawata).

But one thing I can't figure out is the naming conventions for Alexandrians.

Most of the Lalafell (Milalla) have names that are palindromes, and the Viera, Hyur and Elezen seem to have a few options which range from fairly typical-looking names, types of gems/rocks/Earth like Sphene and Geode, and then feelings or emotions like Nostalgia.

For the latter few races, I'm wondering who gets what and why. Why do some people get named after a gem and others get the emotions?

I haven't noticed a pattern really. The first things came to mind is that it may be a class or caste system sort of thing going on?

I know it's too early to get that information probably from any official source--I say as I stare at the pinned naming convention posts--but, perhaps someone has noticed something I didn't?
