How the data was made
- Romanization follows the Revised Romanization of Korean as pronounced: sound changes inside a word are applied (십육 → simnyuk, 백만 → baengman), with no hyphens or capitals. A syllable on its own is read with its final consonant neutralized (꽃 → kkot, 값 → gap, 닭 → dak).
- Numbers: Sino-Korean readings use the 만 (10,000) grouping and drop 일 before 십, 백, 천 and 만 (10,000 = 만, not 일만). Native numbers stop at 99 (아흔아홉); larger counts use Sino-Korean in everyday Korean.
- Names: the standard spelling follows the loanword rules (외래어 표기법) and examples from the National Institute of Korean Language; the alternative is a spelling often seen in Korea (for example 다니엘 for Daniel). Names are written by sound, so real people may spell theirs differently.
- Files are generated by our own code; they do not copy any official rulebook. Official sources: Revised Romanization of Korean · Korean language norms (loanword orthography).
Columns
- korean-syllables-romanization: syllable, Unicode code point, initial/vowel/final letters (jamo), Revised Romanization of the syllable read on its own, and whether it is one of the 2,350 common syllables of the KS X 1001 set.
- korean-numbers-1-10000: number, Sino-Korean reading in Hangul and romanization (as pronounced), native Korean reading for 1–99, and the shortened native form used before counters (한 개, 스무 살).
- english-names-in-korean: English name, standard Hangul spelling under the Korean loanword rules, romanization, and a common alternative spelling if one is widely used.
CSV files are UTF-8 with a BOM so Excel shows Hangul correctly. JSON files hold {title, version, updated, license, source, rows}. Readme and license: README.txt · LICENSE.txt.
