This Korean language resource knows EVERYTHING (국립국어원) | Korean FAQ

Back when I was first starting my channel, I wasn't even aware of the best Advanced level Korean resource online - and it was right there waiting for me the whole time to discover. That is 국립국어원 (The National Institute of the Korean Language), which I recommend for all Advanced level speakers and Korean language teachers.

Have you ever used this resource before, or heard of it?
