What is the last thing you learned?
I’m still learning Japanese from Duolingo, learning a new language as an adult has a different challenge. We have our own logic, why this and why that.
Thinking about how I’m learning a new language when I’m still a kid, I don’t ask many things like the logic behind grammar, how to pronounce, etc.
Duolingo is nice to learn about many new vocabulary, but for politely structured grammar I think I still need a course or formal text book.
