"The man sits."
Can anyone explain "앉"? I mean, not only this one, but blocks that have two "signs" on the bottom. I've noticed that they usually read only the right one (which would be ㅈ here) , so I assumed that it works this way. But here they pronounce only the left one (ㄴ). I'm confused, I don't understand also why they write 있습니다 (why ㅅ 3 times in a row? :O) and many other things, so maybe someone has a good source to help discovering what kind of black magic lays between korean writing and pronounciation?
