Pronunciation tips

It depends on position. Before a vowel, ㄹ is a light tap, closer to a soft r. At the end of a syllable or when doubled, it sounds like l. That's why 사랑 (sarang, 'love') and 물 (mul, 'water') sound different. Romanization writes r or l by position, and ㄹㄹ as ll, but these letters are spelling rules rather than exact English sounds.

Korean consonants come in three types: plain (ㄱ), tense (ㄲ) and aspirated (ㅋ). Say ㄱ softly, ㄲ with a tight throat and no puff of air, and ㅋ with a strong burst of breath. Hold a tissue in front of your mouth: it should flutter strongly only for ㅋ. The same pattern applies to ㄷ·ㄸ·ㅌ, ㅂ·ㅃ·ㅍ and ㅈ·ㅉ·ㅊ.

For ㅗ (o), round your lips and push them forward. For ㅓ (eo), open your mouth a bit more and keep your lips unrounded. Roughly, ㅗ is near the vowel in 'go' and ㅓ near the vowel in 'up.' The first syllable of 서울 (Seoul) uses ㅓ. Practicing in front of a mirror helps you check your lip shape.

ㅡ (eu) is made with unrounded lips stretched slightly sideways and the tongue pulled back in the mouth. Keep your teeth almost closed and say a short 'eu.' English has no exact match, so it feels tricky at first. Practice with words like 크다 (keuda, 'big') and 음악 (eumak, 'music').

In principle ㅐ is pronounced with a slightly wider mouth than ㅔ, but many speakers, especially younger ones, barely distinguish them in pronunciation. So 개 (gae, 'dog') and 게 (ge, 'crab') can sound almost the same in speech. Learn the spelling of each word individually. Even native speakers sometimes clarify by saying 'ㅏ+ㅣ ㅐ' or 'ㅓ+ㅣ ㅔ.'

Many letters can appear as a final consonant (batchim), but they are pronounced as only seven sounds: ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ and ㅇ. For example, the finals in 옷 (ot, 'clothes'), 낮 (nat, 'daytime') and 꽃 (kkot, 'flower') all end in a ㄷ sound. Knowing this rule helps you read new words correctly.

If the next syllable starts with the silent ㅇ, the final consonant moves over and is pronounced as the start of that syllable. This linking is called 연음 (yeoneum). So 음악 sounds like [으막], and 한국어 sounds like [한구거]. Romanization follows the sound, so 한국어 is written hangugeo.

When a final ㅂ is followed by ㄴ or ㅁ, it changes to ㅁ. This is called nasalization (비음화). So 감사합니다 is pronounced [감사함니다], and similarly 먹는다 sounds like [멍는다]. Romanization reflects the actual sound, which is why it is written gamsahamnida.

When a final ㅎ is followed by an ending or suffix that starts with a vowel, the ㅎ is not pronounced. So 좋아요 sounds like [조아요] and 놓아요 like [노아요]. But when ㅎ meets ㄱ, ㄷ or ㅈ, it makes them aspirated: 좋고 sounds like [조코]. That's why 좋아요 is romanized joayo.

In Korean, the same sentence becomes a question with rising intonation and a statement with falling intonation. 밥 먹었어요? (bap meogeosseoyo?) rises at the end to ask 'Did you eat?', while 밥 먹었어요. falls to say 'I ate.' Exaggerating the rise at first is a good way to practice.

ㅢ is a quick 'eu' plus 'i,' but it changes with position. At the start of a word it stays [의], as in 의사 (uisa, 'doctor'). After a consonant it sounds like [이]: 희망 is said [히망]. As the possessive particle 의, as in 우리의 ('our'), it may be pronounced [에]. Romanization always writes it as ui.

After a final ㄱ, ㄷ or ㅂ, a following ㄱ, ㄷ, ㅂ, ㅅ or ㅈ becomes tense: ㄲ, ㄸ, ㅃ, ㅆ or ㅉ. So 학교 (school) is pronounced [학꾜] and 식당 (restaurant) [식땅]. This is called tensification. Romanization doesn't reflect it, so 학교 is still written hakgyo.

When ㅅ comes before the vowel ㅣ, the tongue rises toward the palate, making a sound close to English 'she.' So 시간 (sigan, 'time') and 신발 (sinbal, 'shoes') can sound like 'shi-.' The spelling is still 시, and 쉬 (swi) is a different sound. Romanization writes it as si.

Standard pronunciation rules distinguish vowel length in some words, such as 눈 (nun, 'eye') versus a longer 눈 ('snow'), and long vowels in principle occur only in a word's first syllable. Studies show the distinction has weakened, especially among younger speakers. Learners don't need to master vowel length; context makes the meaning clear.

When a final ㄷ or ㅌ meets the vowel 이, it changes to ㅈ or ㅊ. This is called palatalization (구개음화). So 같이 ('together') is pronounced [가치], and 굳이 ('necessarily') sounds like [구지]. Romanization follows the sound, so 같이 is written gachi.

When ㄴ meets ㄹ, the ㄴ turns into ㄹ, producing a double l sound. This is called liquidization (유음화). So 신라, the ancient kingdom, is pronounced [실라], and 연락 ('contact') sounds like [열락]. Romanization follows the pronunciation, giving Silla. The same rule explains why 한라산 (Hallasan) is pronounced with a double l.

Say ㅈ (j) softly, ㅉ (jj) tensely with no puff of air, and ㅊ (ch) with a strong breath. Practice with 자다 (jada, 'to sleep'), 짜다 (jjada, 'salty') and 차다 (chada, 'cold' or 'to kick'). Because the meanings differ, the distinction matters. Hold your palm in front of your mouth to feel the difference in airflow.

At the start of a syllable, ㅇ is silent; it is a placeholder that lets a vowel stand alone. So 아 (a) and 오 (o) are pronounced as just the vowels. As a final consonant, however, ㅇ sounds like the 'ng' in 'sing,' as in 강 (gang, 'river'). The same letter plays two roles depending on position.

Shadowing works well: listen to a native speaker and repeat immediately, copying intonation and speed. Choose short sentences, record yourself and compare with the original. Using real material, like drama lines or news sentences, makes practice more useful. Short daily sessions beat occasional long ones.

A common mistake is adding a vowel after the final consonant, so 밥 (bap, 'rice') becomes 'ba-beu' and 책 (chaek, 'book') becomes 'chae-keu.' Korean finals are unreleased: the sound stops without an extra vowel. End 밥 with your lips closed, and 책 with the back of your tongue blocking the air. Slow practice helps quickly.
