If you lived on a border of a country that speaks different languages how is it chosen what language you speak? If you lived on the border do you just learn both languages?
Or is it more if you lived even like 500 meters of a border do you learn the language of the country your in? Do people choose it based on nearest popular city to where they’re at?
You realize that speaking a language involves talking to another person, right?? So you speak what the interlocutor speaks in any given situation… and if both parties speak both equally well, then they generally speak a mix of both, based on whim or topic.
Such people are sometimes called Grenzemensch (border person). They grow up speaking multiple languages and don’t even realize til they’re older that the languages are different. They just think you have to talk to Uncle Fritz one way and Grandma Mireille a different way.
The trick is that in German it’s fine to just take several words and delete the spaces between them if they’re expressing a single concept. Like if in English, we took the concept of Germans having a word for everything and just called it Germanvocabulary
Language isn’t defined by borders. What people speak in an area is what they grew up speaking and have learned to speak.
I speak a little Spanish, but no Portuguese, and my time in Brazil right near the border with two Spanish speaking countries was a challenge, because most folks there didn’t speak Spanish despite the location.
Some folks do of course, but most people I encountered didn’t have any Spanish
I have zero idea how representative that is of other borders
I guess you visited Iguazú… we have kind of a funny situation there cause we tend to understand each other “pretty well” while still speaking our own languages. That has to do with how similar our languages (and cultures) are and with how cool and welcoming brasilian people is.
Speaking both seems like a great choice.
