So I did a live stream a while back where I taught how to use ~걸.
This includes the many meanings of ~걸, "girl," ~것을, ~걸 and ~걸요, and a few others.
But the most important part is that I wore a lot of hats on my head. A lot.
You can learn about ~걸 and how to use it, or you can just look at all the hats on my head.
