I will go with silence's translations but will romanise them as best as I can. It's not 100% just a guideline. who/where/what/how / why 누가/어디서/무엇을/어떻게/왜 nu-ga/ oh-di-so/mu-oh-sul/ oh-toh-kay/way what are you doing? 뭐 하세요?(shortly) / 무엇을 하고 있으세요?(direct translation) mu-o ha-say-yo?/ mu-oh-sul ha-go eesuh-say-yo what is your name? 이름이 뭐에요?(shortly) / 당신의 이름이 무엇인가요?(direct translation) ee-rum-ee mu-o ay-yo? / dang-shin-ay ee-rum-ee mu-oh-shin-ga-yo? how old are you? 몇 살이야?(shortly and with friend) / 당신의 나이가 어떻게 되세요?(direct translation, polite expression) myot sal-ee-ya? / dang-shin-ay na-ee-ga oh-toh-kay duay say-yo? i am ..... 나는 ~입니다. na-nun --- im-ni-da what happen? (not sure on the english. do you mean; what happened? or what is happening?) 무슨 일이야?(direct translation) mu-sun il-ee-ya? good luck
