BASICS: Introduction to Korean Grammar
If, like me, you found the alphabet really easy but started floundering as soon as sentences were introduced, read this!
It explains the basics of what's going on. Sentence order and so. And the 'particles' that people keep talking about in the discussions. It has nothing to do with CERN apparently.
Duolingo's 'make everything as simple as possible' attitude on the mobile apps makes the lessons on the alphabet too easy and throws you in way too deep when any grammar starts appearing. You're left there wondering, "Erm, what happened to man? Why is it now spelt manliongdidlibob?" with no explanation.
One of the hardest things to wrap your head around in Korean is the alien-like sentence structure.
Hah, yeah right. I had to learn German ;-)
