(Have you been doing well?) 계신가요 = 계시다 + ㄴ가요 계시다 is used when the subject in question is someone we respect, usually an elder. 있다 is used when talking to a friend. ㄴ가요? indicates a question. Another variant of "ㄴ가요?" is "나요?" --- 2) 오늘도 좋은 하루 보내세요! Have a nice day today too! 좋은 = 좋다(good) + 은 It explains what kind of 하루(day) it is. 좋은 하루 = good/pleasant day 보내세요 = 보내다 + (으)세요 보내다 means "send (something though some kind of passage)" 시간을 보내다 means "to spend time" 소포를 보내다 means "to send a package" 하루를 보내다 means "to go though a day" (으)세요 is the more formal form of 아/어/여요. ps: 韩语是个黏着语。和中文、英语比起来，相当的不同
