Korean pronouns
Second person reference
Leaving out the subject of the sentence if it can be implied by the context. In English, sentences need explicit subjects, but this is not so in conversational Korean. Using the person's name when talking to someone younger. With older people, it is custom to use either a title or kinship term (see next point). Using a kinship term: 언니 (eonni, "older sister" if speaker is female), 누나 (nuna, "older sister" if speaker is male), 오빠 (oppa, "older brother" if speaker is female), 형 (hyeong, "older brother" if speaker is male), 아줌마 (ajumma, "middle-aged woman"), 아주머니 (ajumeoni, also "middle aged woman" but more polite), 아저씨 (ajeossi, "middle-aged man"), 할머니 (halmeoni, "grandmother") of 할아버지 (harabeoji, "grandfather"). In Korea, it is common to use kinship terms for people who are not family at all. The term 아가씨 (agassi, "young lady") is preferable when addressing a young girl of unknown age. It is seen mostly used in public places like restaurants, but it will also sometimes be used by men in pick-up lines. By definition, the actual difference between 아가씨 and 아줌마 reside in marriage status and not age. Using the appropriate title, usually ending in -nim: seonsaengnim ( 선생님, "teacher" although it is also often used as a general honorific term for other professions like managers) or gwajangnim (과장님 "director"), etc. Using the plural yeoreobun (여러분, "ladies and gentlemen") where applicable. If none of the above is possible, an honorific common noun, such as dangsin (당신, "said body") or jane (자네, "oneself") (used for "you" in the familiar speech level). The pseudo-pronoun dangsin is actually a noun, from the Sino-Korean loanword 當身 "the aforementioned body". There are many such pseudo-pronouns in Korean.
