Jakmyeong (작명): how names are chosen with saju in Korea

In Korea, choosing a name can be a small family project. Many families consult specialists in jakmyeong (작명), the art of creating names, so that the name balances the baby's saju. Behind it are Chinese characters with meaning, an official list of permitted characters and the idea that every character has an element. Here is how it works.

Names with written meaning

Most Korean names have a one-syllable surname and a two-syllable given name. Although they are written in hangul, many syllables of the given name are also chosen for their Chinese character, the hanja (한자). This matters because the same syllable can match many different characters. "Seo" can mean something auspicious, the west or a book, depending on the hanja chosen. That is why two people with the same name in hangul can have names with very different meanings. Choosing the character is like choosing the exact shade of a paint: from a distance they look the same, but up close they tell a different story.

The official list of characters

In South Korea you cannot use just any hanja in a name. There is an official list of characters for personal names, the inmyeongyong hanja (인명용 한자), set by the Family Registration rules administered by the Supreme Court. The list has been expanded several times: according to the Korean legal press, one of those expansions took it from 8,319 to 9,389 characters. Before registering a name, families or specialists check that the character is allowed. So jakmyeong has a very practical side: besides seeking beauty and harmony, you have to make sure the name can be legally registered.

Jawon ohaeng: the element of each character

This is where saju comes in. In the method called jawon ohaeng (자원오행), each hanja is classified into one of the five elements according to its meaning and its graphic root. A character with the tree (木) or grass (艹) radical is linked to wood. One with the water (氵) radical is linked to water. So if a baby's chart has very little water, the specialist might propose a water character to balance it. The underlying idea is lovely: a name stays with a person for life, so it becomes a kind of charm spoken aloud every day, bringing what the chart was asking for.

Sound, strokes and harmony

The character's element is not the only thing that counts. Many jakmyeong schools also analyze the sound of each syllable, since Korean consonants are linked to different elements, and the number of strokes in each hanja, which are combined in search of favorable numbers. On top of that comes something very human: that the name sounds good with the surname, is easy to pronounce and will not invite teasing at school. A good specialist balances all these layers. That is why it is not unusual for a family to receive several proposals, each with an explanation, and end up choosing the one that sounds best to them.

Jakmyeong today

Today many ways of naming coexist. There are traditional naming studios, apps that suggest names based on birth date, and families who prefer purely Korean names with no hanja at all. For people from other countries, jakmyeong has become a charming curiosity: choosing a Korean name that reflects your character or balances your chart. If you want to try, start with your saju: see which element you have least of, and look for a sound and a meaning you like within that element. It does not replace your name, of course. It is more of a nickname with intention, a way to carry a bit of the element you are missing.
