Used to (던, ㅆ던, ㅆ었다, 곤 하다, 던데) | Live Class Abridged

I've been asked to explain ~던 for a long time, and was able to put together a live stream about it.

It's not as simple as just teaching ~던, since ~던 is related directly to several other grammar forms in the past tense - namely the 곤 하다 form, double past tense (ㅆ었다), and 던데(요).

So in order to teach ~던, we'll be learning all of these concepts.
