I forgot a couple of words in my list yesterday. Keeping in mind that I'm estimating the spelling of these: kure seems to mean "right, exactly", and (cool Japanese coincidence, or areal feature?) ka is used to end question sentences. Also, annyeong (ahn - nyawng) means "Ok, fine, I'm fine, it's nothing, no, never mind" (I know the spelling of this one from the intro Korean website, since it's part of the hello/goodbye formula).
Today I figured out that kurukkheyo (definitely estimating here) means "I know" or "I see, I understand". Yay!
