I genuinely hate how English is becoming a sort of de facto global language. Just more cultural imperialism. But it's very nice to be able to communicate with comrades from around the world, it might be my favorite aspect of this site. So I do appreciate you all taking effort to think something in your native language, translate it in your head, then type it up in English. Hopefully in FALGSC we'll get our universal translators, too.
For real, learning languages is hard. I had 2 years of Spanish in high school and didn't do too well, something in my brain just didn't click. But maybe you need to use another language a lot to really learn it? I lived in Germany for just two months and by the end I found myself kinda picking up things.

Sorry, I meant structurally, rather than in terms of performance. That's why I added a clarification that the advantages of being young can still be overcome in adulthood.
But MRI studies do show differences in how language is processed/encoded for younger vs older language learners. There are also differences related to exposure to language as an infant, but that's a whole other topic.
