Jeong-ja
Korean female given name (정자)
Jeong-ja, also spelled Jung-ja, Jong-ja, or Chung-ja, is a Korean given name.
Typically, "ja" is written with the hanja meaning "child" (子). In Japan, where this character is read ko, it was originally used as suffix for the names of girls in the aristocracy. The practice of adding -ko to girls' names spread to the lower classes following the 1868 Meiji Restoration. Jeong-ja is one of a number of Japanese-style names ending in "ja", along with Young-ja and Soon-ja, that were popular when Korea was under Japanese rule from 1910 to 1945, but declined in popularity afterwards. According to South Korean government data, it was the sixth-most popular name for baby girls in 1940. By 1950 there were no names ending in "ja" in the top ten.

Why this record matters
The phrase “korean female given name (정자)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 11, 2025. The linked authority identifier is Q6180222. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1868, 1910, 1945 and 1940.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
