Re: Ethiop. I'd say it's more complicated than that. The first syllable ae is common in sun-related words; one Greek name for the sun is aelios and the first and second together aith are seen in sun words like aithousa the greek word for veranda. The proposed PIE root for sun -el- also suggests that heli- based greek sun words are related to aeli- ones. So burnt faces may miss important context. Given the Greeks saw them as living near the sun sunburnt might be the meaning but im no classicist.
Like, honestly? That’s what I think is most likely, but people can make up their own minds. I kind of encourage that sort of thing.
It’s just there’s this immense dominant narrative around Greco-Roman constructs of whiteness, and anything that challenges that is going to be called “fringe” or just dismissed. Pretending like just because something is “well-established” makes it “factually correct beyond questioning” is how you end up with so much garbage that permeated the popular consciousness about history and what “everyone just KNOWS”.
