How does Korean relate to this? I speak it semi-fluently and none of those three things happen in it. I have however found its folding in of adjectives into verbs one of several useful toeholds for learning Lojban, though.
It doesn't directly relate. I'm currently learning Korean and don't want to try learning multiple languages at the same time. Also, I want a broader experience with languages before I try to make my own.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
