The story of Sun
East Asian names lose a great deal in the crossing. Korean given names are usually two syllables, each written with a character chosen for its meaning, and romanizing them into English drops both the characters and the tones that distinguish them; a whole set of different Korean elements come out as Sun. The Chinese surname is a separate matter and arrives in American records as a surname used as a given name, or as a given name in its own right. English speakers meanwhile read the three letters as the star, which is the one thing none of the other traditions meant.
Meaningscholars disagree
grandson; descendant
The Chinese surname written Sun means a grandson or a descendant, and it is among the most common family names in China. Korean given-name elements romanized as Sun cover several different characters and mean different things — goodness, purity, and others — because Korean romanization flattens distinctions the writing system keeps. And the English word is the star, from a root shared across the Indo-European languages. Which of these applies is a family fact, and the spelling records none of it.

SOON
SOON is closer to the Korean and Chinese vowel than the English word is. American readers say SUN, rhyming with fun, which is the English word rather than either original. Both are heard, and which one a family uses tends to follow which language the name came from.

The trade-off
- Three letters and one syllable, which fits against any surname without crowding.
- It is a working name in Korean and Chinese as well as an English word.
- It goes to boys and girls both, and none of the source traditions decides for it.
- English readers will see the star and say the English word, whichever language the name came from.
- The romanization drops the character and the distinctions it carried, so the written name is incomplete in its own language.
- A three-letter name gets treated as an abbreviation by forms and filing systems, and it will be queried.
