I only know a few phrases in Korean, (the spoken language is called Hangul Mal, or at least it's pronounced that way.) My favorite word/phrase is "opseyo." (the "op" part is pronounced sort of half way between oop and owp.) It means "we're out, all gone, not there, it doesn't work." "Muleyo" (moo-lye-oh) means "I don't know." "Cho sum ni da" means "good," "fine" "OK." "Neh" (nay) means "yes," and "aniyo" means "no."
