What Is Korean Romanization?
Korean romanization is a set of rules that maps Hangul to the Latin alphabet. Some systems follow the sound of a word (transcription), and others follow its spelling letter by letter (transliteration). The difference shows in 종로, a district of Seoul: it is spelled with ㄹ but said [종노], so a sound-based system writes Jongno.
Romanization is a supplement to the Korean alphabet, not a replacement. It helps a traveller read a subway map, but it cannot teach the sounds, because Korean has contrasts that English letters do not mark.
Which Romanization Systems Exist?
Three systems matter for learners, and each serves a different reader.
| System | Created | Follows | Marks | Main use today |
|---|---|---|---|---|
| Revised Romanization (RR) | 2000, South Korean government | pronunciation | none | signs, maps, passports in South Korea |
| McCune–Reischauer (MR) | 1939, McCune and Reischauer | pronunciation | breves ŏ ŭ, apostrophes | North Korea (MR-based), libraries, older books |
| Yale | 1940s–50s, Yale linguists | spelling | none | linguistics and some grammar books |
South Korea used a modified MR from 1984 until RR replaced it on 7 July 2000. A short definition of each system is in the glossary: Revised Romanization, McCune–Reischauer and Yale romanization.
Korean Romanization Systems Compared
The same six words show how far the systems can drift apart.
| Hangul | Meaning | RR | MR |
|---|---|---|---|
| 서울 | Seoul | Seoul | Sŏul |
| 부산 | Busan | Busan | Pusan |
| 한글 | Hangul | Hangeul | Han'gŭl |
| 김치 | kimchi | gimchi | kimch'i |
| 거북선 | turtle ship | geobukseon | kŏbuksŏn |
| 독립문 | Independence Gate | Dongnimmun | Tongnimmun |
Yale, which follows spelling, writes 서울 as sewul and 한글 as hankul. Every letter of every system is listed in the Korean romanization chart.
Revised Romanization Rules
Revised Romanization rules come from 국어의 로마자 표기법, the Ministry of Culture and Tourism notice of 7 July 2000. The core idea is "write the standard pronunciation with fixed letters": vowels such as ㅓ and ㅡ become eo and eu, and sound changes are written as heard, so 신라 [실라] is Silla.
The full Korean romanization rules come with examples, including which sound changes RR records (Jongno, Silla) and which it ignores (tensification, as in Apgujeong). The lesson also covers the separate transliteration mode for academic use, which follows spelling instead of sound.
Revised Romanization vs McCune–Reischauer
Revised Romanization and McCune–Reischauer disagree mainly on word-initial consonants and on special marks. MR writes 부산 as Pusan, with p for the first sound; RR writes Busan. MR adds breves and apostrophes; RR uses plain letters only.
For older books and North Korean sources, compare Revised Romanization vs McCune–Reischauer. That page converts MR spellings such as Kimpo and Taegu back to modern RR and Hangul.
Romanizing Korean Names
Korean names follow habit more than rules. Most people choose their passport spelling, so the surname 이 appears as Lee, Yi or Rhee, and 박 as Park rather than the RR form Bak.
Names follow their own habits: see romanization of Korean names. It explains surname spellings, hyphens in given names and how to find one person under several spellings.
Why Does Korean Romanization Look Wrong?
Korean romanization looks wrong because English letters stand for different sounds in English. Readers say eo as two vowels and expect g to sound like English g, but Korean ㄱ at the start of a word is voiceless and lightly aspirated, closer to the k in "skin" than to the g in "go".
The eo, eu and g/k puzzles are explained in why Korean romanization looks wrong. It is the best page to read if romanized names keep surprising you.
Which System Do You Need?
Choose the system by what you are reading or writing. Most learners need RR for the outside world and no romanization at all for study.
| Your task | System | Why |
|---|---|---|
| Reading signs, maps, addresses in South Korea | RR | the official standard since 2000 |
| Reading pre-2000 books, old maps, North Korean sources | MR | the standard of those sources |
| Reading linguistics papers or reference grammars | Yale | follows spelling, shows word structure |
| Writing your own name | personal choice, often RR | passports accept established spellings |
| Learning pronunciation | none | use Hangul and audio |

Should Learners Use Romanization?
No, not for study. Romanization helps for the first hour, but it hides contrasts that change meaning: 불 (fire), 뿔 (horn) and 풀 (grass) begin with three different sounds, written bul, ppul and pul in RR, and an English reader cannot hear the difference from the letters. Learn the letters first: Hangul has 40 letters, a small set compared with the thousands of Chinese characters once used to write Korean. Plan your switch to learning Korean without romanization.
What romanization cannot do: no system shows the difference between plain, tense and aspirated consonants in a way English speakers can pronounce, and none shows Korean intonation. Treat every romanized word as a label, then check the Hangul and the audio.
Practice: Romanize 10 Common Words
Write each word in Revised Romanization, then check the answers.
- 사랑 (love) 2. 한국 (Korea) 3. 감사 (thanks) 4. 부산 (Busan) 5. 제주 (Jeju) 6. 김밥 (gimbap) 7. 같이 (together) 8. 종로 (Jongno) 9. 신라 (Silla) 10. 학교 (school)
Answers: 1 sarang, 2 hanguk, 3 gamsa, 4 Busan, 5 Jeju, 6 gimbap, 7 gachi, 8 Jongno, 9 Silla, 10 hakgyo. Items 7 to 9 follow pronunciation, not spelling: 같이 is said [가치], so RR writes ch. If those three were wrong, read the rules lesson next.
Korean romanization is a tool for names and signs; Hangul is the tool for learning Korean.
Frequently Asked Questions
Is romanization the same as pronunciation? No. Romanization is a spelling convention that maps Korean to Latin letters, not a recording of sound. 어 is written eo, but it is one vowel, not e followed by o. 김치 is gimchi, yet the first sound is between English g and k. Use romanization to recognise names and signs, and use audio to learn sounds.
Do Koreans use romanization? Rarely among themselves. Koreans read and type in Hangul. Romanization appears where foreigners need it: road signs, subway maps, passports, company names and addresses written in English. Many Koreans romanize their own names by habit rather than by the official rules, which is why spellings such as Lee, Park and Choi stay common.
Is there a romanization converter? Yes. Our Korean romanization converter turns Hangul text into Revised Romanization and shows which rule it applied, such as the ㄴ to ㄹ change in 신라 (Silla). A converter is useful for names and signs. It cannot fix established spellings like Samsung or Lee, which follow tradition rather than the rules.
Why do K-pop names use different spellings? K-pop names are brand choices, not official romanizations. Agencies pick spellings that look good or are easy to say in English, such as Jungkook or Taeyeon, and they may hyphenate, join or space syllables freely. Revised Romanization applies to government use, so stage and personal names often ignore it.
Is kimchi a Revised Romanization spelling? No. Under Revised Romanization 김치 is gimchi, because ㄱ at the start of a word is written g. The spelling kimchi is older and established in English, so it stays on menus, packaging and in dictionaries. The same is true of many brand names: Samsung would be Samseong under the rules.
