Luis Sera is a language genius.
Some more interesting Luis thoughts? I went over it a bit on this post, but I wanna speak about the fact that he is a linguistic master.
We know Luis can canonically speak European/Castillian Spanish and English. But did you know that Luis can probably speak Latin, and also, different forms/dialects of Spanish as well?
So Spain is where the original Spanish originates from - that is where Luis is from. In Spain, a specific dialect of Spanish is spoken that is different if not,a completely different language from the Spanish you'd hear in the States or in other places in Latin America - it is called Castillian. It's closer to like, Latin and Portuguese (Portugal Portuguese!). The reason there are different dialects of Spanish is because Spain (where Luis is from) colonized/imperialised other nations for slavery, land, etc. Indigenous people ended up being forced to learn Spanish, so did African people thus - we have different variations of Spanish. Those dialects of Spanish, are not taught in Spain.
So back to Luis. When Luis leaves Valdelobos and ends up coming to the US, it is very possible that he cannot actually understand or communicate with the variations of Spanish spoken in the US or in Latin America. He is not the same nationality/ethnicity etc., as latin people or Hispanic people, etc. So Luis had to actually learn how to speak different dialects of Spanish which to him, is essentially a different language from Castillian. But what we can gather is that, because he is smart, Luis probably learned it easily, and learns it in such a way to not mix it up with his Castillian.
Luis also probably knows how to speak various forms of Castillian spanish. Valdelobos is isolated, so while yes, he speaks Castillian that is common in his village, Spain is modernized and their dialect of Castillian and how they speak, is going to be different from Valdelobos, which is still stuck in the 1700rds.
Luis also speaks Latin. Castillian is close to Latin, they are extremely related. However, Valdelobos is a Catholic town, and I mean, pre 2000s Catholic. Again, stuck in the 1700rds - Vatican I kinda Catholic. Which means that for Luis and his religious village to communicate, and interact in church services, mass, Latin was a must. The scripture, liturgy, everything said done in Latin. Luis probably learned this from a very, very, very young age because it was embedded in his culture.
Now, Luis can speak English- and it's more than likely, English is both his first and second language. Castillian is his first language, but Luis himself probably also grew up speaking English. Even for a Spanish town stuck in the 1700rds, it wouldn't be out of the ordinary for people to know English when it came to things like trade, politics, etc. Salazar, spoke English - which is more understandable as a noble/mayor like figure. But I wouldn't be surprised if like Latin, English was a language that was taught along side.
Luis can also probably speak Italian - no actually background for that, I'm just assuming he can - probably better than Leon lol. This is probably because in my hc, unlike his husband Leon, Luis is very catholic.
Do you think there's any other language Luis can speak?
