How Korean names are chosen
Korean given names are usually two syllables, and traditionally only one of them is really 'yours'. The other is the dollimja, a generational syllable shared by every sibling and paternal cousin of the same generation — which is why siblings so often sound alike. Which syllable falls to which generation is not improvised: it is recorded in advance in the family's jokbo, the genealogy book, and frequently rotates through the five elements, each generation's syllable carrying the hanja radical for the next element in the cycle. Urban families follow the system loosely now, but it is still live in more traditional households.
Most Korean names are written in hangul day to day but derive from hanja, so a name has a Korean sound and a separate Chinese-character meaning behind it.
