>I prefer to use the grammatically correct and gender neutral latine/latines.

As a Spanish speaker, can you explain to me why latine/latines is grammatically correct? Or are you trying to say it's grammatically correct in the language of the people trying to force it onto Spanish speakers?

Exactly this! I think non-gendered adjectives are a nice addition to Spanish and many people are starting to use it! Adding "-e" to the end of words is far more commy tham adding x to it. Latinx sounda really weird in Spanish and latine sounda way better, it also integrates netter with other parts of the language, you can say ingeniere, aliade, but ingenierx or aliadx sounds amd looks weird and ugly.

I'm guessing Spanish doesn't have this because it doesn't do noun declination as much, but Latin does have the concept of a "common" grammatical gender that is distinct from the neuter, for words that apply to people or animals but that aren't specifically masculine or feminine.

I wasn't aware "latine" was being used in Spanish.

Out of curiosity, how do you decide how other words agree with it, like la/el and adjective endings?
