What a mixed Nahuatl-Quechua language would be like if Aztecs and Incas were put on another world terraformed by Aliens for them? Might they eventually become Monotheistic like Hebrews due to past Pagan excess independently of them? I will call these mixed Nahua-Quechua people the Lunah which is their endonym!
Kallawaya and Media Lengua are Quechua-Derived Mixed Languages so there's precedence. https://en.wikipedia.org/wiki/Kallawaya_language
Singular for Lunah is Lunatl btw...
