What is the difference between eotteon, museun, and mwo/mueot in Korean? 1.For example : Museun/eotteon yonghwareul polkkayo? (What film do you want to see?) Question : Are museun and eotteon always used before noun in question sentence? 2.For example : Igeoseun mueosimnikka? (What is this?) Question : Igeoseun means this things? If the answer is yes, that means igeoseun includes in noun, but why uses mueot/mueos, not eotteon/museun? 3.For example : Oneureun museun yoil imnikka? (What day today?) Yoil means day and day includes in noun, if I want to say "Oneul yoireun mueosimnikka?", is it right or wrong? Thanks for the time to answer my questions.
