Korean name

A Korean name in the modern era typically consists of a surname followed by a given name, with no middle names. A number of Korean terms for names exist. For full names, seongmyeong (Korean: 성명; Hanja: 姓名), seongham (성함; 姓銜), or ireum (이름) are commonly used. When a Korean name is written in Hangul, there is no space between the surname and the given name.^[1]

Most Korean surnames consist of a single syllable, although multisyllabic surnames exist (e.g. Namgung). Upon marriage, both partners keep their full names, but children inherit the father's surname unless otherwise specified during the marriage registration process. Koreans have been historically grouped into Korean clans. Each clan is identified by a bongwan (본관; birthplace of the clan's founder) and the founder of the clan (with descendency determined patrilineally). For example, the Jeonju Yi clan comes from Jeonju and descends from Yi Han [ko].^[2] In 2000, a census showed that there were a total of 286 surnames and 4,179 clans.^[3] However, the three most common surnames (Kim, Lee, and Park) are shared by nearly half of South Koreans.

Given names usually have two syllables, although names with one, three, or more syllables also exist. Generation names (where names for a generation of a family are related in some way, usually by sharing a character) are also traditional, although now increasingly less common. In North Korea, the generational syllable is shared only among siblings, but in the South, it is shared by all members of the same generation. The use of given names is guided by a strict system of honorifics; it can be rude to refer to a stranger or person of higher social status by their given name. Perceived gender in names is less consistent than in Western names.

Naming practices have changed over time. Surnames were once exclusively used by royalty and nobility, but eventually became acceptable for lower class usage. Even until 1910, more than half of Koreans did not have a surname. While now significantly less common, Confucian and cultural traditions dictate systems of naming taboos, childhood names, courtesy names, art names, and posthumous names. Until the invention of the Korean alphabet Hangul in the 15th century, most Korean names were written using Chinese characters (Hanja). While many names can still be written entirely in Hanja, some are now exclusively written in Hangul (e.g. Da-som). In 2015, 7.7% of people had Hangul-only names. During the Japanese occupation of Korea, beginning in 1939, Koreans were forced to adopt Japanese names and naming practices. They were allowed to return to using Korean names following the 1945 liberation of Korea.
