Romanization is a spelling system, not a pronunciation guide. It tells you which Hangul letters a word has, but it can’t show the sounds English doesn’t have, the changes it chooses not to write, or how Korean names are really said.
Revised Romanization (RR) uses only the 26 English letters. That keeps it easy to type, and it means some Korean sounds get squeezed into letter pairs that English readers will say the English way. Below are ten mistakes that come from reading romanization too literally. Each one is something a romanizer, including ours, can’t fix by itself. The fix is to read the Hangul and know what the letters stand for.
The checklist
1. Saying “eo” as two vowels
ㅓ is written eo, so many learners say “ee-oh.” It is one vowel, made with the mouth open and the lips relaxed, close to the “u” in cup or the “aw” in a British saw. 서울 is Seo-ul, two syllables: seo + ul. It is not “Sole” and not “See-oh-ul.”
2. Saying “eu” as “you”
ㅡ is written eu. It is a single vowel with flat, unrounded lips, a bit like the sound in the middle of good said with a smile. 음식 (eumsik, food) starts with that sound, not with “you.”
3. Expecting ae and e to sound different
RR writes ㅐ as ae and ㅔ as e, which suggests two clearly different vowels. In everyday Seoul speech, most people now pronounce them the same, close to the “e” in bed. 개 (gae, dog) and 게 (ge, crab) usually sound identical, and Koreans tell them apart by context or spelling. Don’t strain to make “ae” sound like the “a” in cat.
4. Reading ㅢ the same everywhere
ㅢ is written ui in every position, but the standard rules allow it to change with position:
| Where ㅢ appears | Said as | Example |
|---|---|---|
| Start of a word, no consonant before it | [의] | 의사 uisa, doctor |
| After a consonant | [이] | 희망 [히망] himang, hope |
| Not the first syllable | [의] or [이] | 회의 [회의/회이] hoeui, meeting |
| The particle 의 (“of”) | [의] or [에] | 나의 [나의/나에] naui, my |
The romanization stays ui in every case, so only the Hangul and the rule tell you what to say.
5. Missing the “sh” in si
ㅅ before ㅣ sounds close to English “sh.” RR writes 시 as si, but the word 시간 (sigan, time) is closer to “shi-gan” than to “see-gan.” The same happens before ㅑ, ㅕ, ㅛ and ㅠ: 셔츠 (syeocheu, shirt) is said “shuh-cheu.” You can hear this on any of the ㅅ syllables in the Hangul chart.
6. Treating r and l as two letters
ㄹ is one letter. RR writes it as r before a vowel and l at the end of a syllable, so 사랑 is sarang and 물 is mul. Between vowels, it is a quick tap of the tongue, like the “tt” in American butter, not an English “r.” At the end of a syllable, it is a light “l.” The romanization makes it look like two different sounds, but it’s one letter, said according to where it sits.
7. Releasing final consonants
At the end of a syllable, ㄱ, ㄷ and ㅂ are not released. Your mouth closes for the sound and stops there, with no puff of air. 밥 (bap, rice) ends with your lips shut, not with a “puh.” 옷 (ot, clothes) ends with your tongue held behind your teeth. Romanization writes a full p or t, so learners add a little extra sound that Korean doesn’t have.
8. Missing the hidden tense sounds
After a final ㄱ, ㄷ or ㅂ sound, the next plain consonant usually turns tense. RR doesn’t show this at all:
학교 "hak-gyo"
식당 "sik-dang"
국밥 "guk-bap"
[학꾜] hak-kkyo = school
[식땅] sik-ttang = restaurant
[국빱] guk-ppap = rice soup
This is the main place where RR and pronunciation part ways on purpose. RR does follow most sound changes, such as 한국말 → hangungmal, but it leaves tensing out. Our post on Korean sound changes covers the rules RR does spell.
9. Saying g, d, b like English
RR writes ㄱ, ㄷ, ㅂ as g, d, b, but at the start of a word these are not the voiced English sounds. They are closer to a soft “k,” “t,” “p” with a light puff of air and a lower pitch on the vowel. Between vowels they do become voiced, so 바보 (babo, fool) really does have two b-like sounds. Then each has two partners: aspirated ㅋ ㅌ ㅍ (k t p) and tense ㄲ ㄸ ㅃ (kk tt pp). Telling all three apart takes listening practice. Our tense consonants guide ends with a short listening quiz.
10. Reading surnames the way they’re spelled in English
Most Korean surnames have a traditional spelling in passports and the media that is not RR, and reading it the English way gets the sound wrong:
- 이 is spelled Lee, but there is no L sound. It is said [이], like “ee.” (RR would be I.)
- 박 is spelled Park, but there is no R. It is said close to “bahk.” (RR: Bak.)
- 최 is spelled Choi, but it is said close to “chweh,” not “choy.” (RR: Choe.)
The Korean romanizer shows the usual spelling next to the RR form for common surnames, so you can see both.
What to do instead
Use romanization for the first few days, then switch to Hangul as soon as you can read it. Learning Hangul takes a weekend, and the letters themselves carry the information that romanization drops. The plain, aspirated and tense consonants each have their own shape, and ㅓ and ㅡ are visibly different vowels.
For the sound changes that spelling doesn’t show, practice with real words. The Korean pronunciation practice has 20 words where you pick the actual pronunciation and see the rule behind it. For the vowels, see the Korean vowels that trip up beginners.
