I'm translating a Mexican fairy tale and I need your perspective on some things and a bit of explanation here and there

while I was able to find some stuff by googling it there is also something I couldn't find and can't understand.

any people of spanish or mexican origin that can spend a bit of their time right now and tomorrow on my questions about ur fairy tales culture and whatnot (some of them might be really stupid and obvious but I still need some help with that "for scientific reasons") - post here or hit me up on steam
