Sino-Korean vocabulary
Koreans usually have a one-word family name of Chinese origin and a two-word given name also of Chinese origin. Traditionally, one word in the given name would be the same as all the person's siblings, and the other would be unique to themselves. Examples include Park Geun-hye (hangul: 박근혜, hanja: 朴槿惠) and Kim Jong-un (hangul: 김정은, hanja: 金正恩). Some Koreans, however, have a two-word family name of Chinese origin, like Namgung (hangul: 남궁, hanja: 南宮) and a one-word given name of Chinese origin like in Namkung Do (hangul: 남궁도, hanja: 南宮道). In other cases, Koreans may have a one-word given name and a one-word family name. An example of this is Go Soo (hangul: 고수, hanja: 高洙). Nowadays, however, it has become more common for Koreans to have their given name be a native Korean word, like Haneul (hanja:한을, meaning: "Heaven"/"Sky"), Areum (hanja:아름, meaning: "Beauty"), Iseul (hanja:이슬 "Dew"), and Seulgi (hanja:슬기, meaning: "Wisdom"). On official documents, Koreans must write their names in hanja and hangul. For native Korean names, Koreans chose hanja that just have the same pronunciation as the word's syllables rather than hanja that have the same meaning.
