Seems unlikely. The Andorrans have chosen to stay independent this long; why would Catalan independence change that?
It's in the link I shared.
The historic and official language is Catalan, a Romance language. The Andorran government encourages the use of Catalan. It funds a Commission for Catalan Toponymy in Andorra and provides free Catalan classes to assist immigrants.
Mother tongue %
Catalan 38.8%
Spanish 35.4%
I know they speak Catalan in Andorra. But they also speak Spanish and have never expressed the slightest desire to join Spain. Moreover, nationality is about more than language, else why wouldn't Austria merge with Germany? Or Luxembourg with France? Or, maybe most to the point, San Marino with Italy?
Luxembourg main language isn't French, but Luxembourgish.
My mistake. I interact professionally with people in Luxembourg a lot, and they always prepare their documents in English and French and have French names, so I assumed it was mostly French-speaking these days. I guess that's only true at the business/international level?
Well there is a couple of things there. The people you deal with quite possibly are French, as Luxembourg has both a huge (like 30% of the population) level of immigration, and in addition, there is a major phenomena of commuters crossing the border from France to Luxembourg each day.
Luxembourg also has a somewhat unique linguistic situation, as kids do school in French, German and Luxembourgeois, and in day to day life, different things work in different languages (for instance, I believe the convention is that shopping is done in French, but legal correspondence is in German) - so in effect, every Lucembourger uses four languages as part of their daily life.
Most Luxembourgers I have cone across habe more Germanic sounding names though eg Andy Schlek
Do you count English as the fourth?
