Korean Pronunciation Rules Made Simple: Linking, Nasalisation, Tensing, Aspiration and Palatalisation with Examples

If Koreans don't understand you even though you read every letter correctly, pronunciation rules may be why. We explain the seven final-consonant sounds, linking, nasalisation, liquidisation, tensing, aspiration, palatalisation, ㅎ-dropping and more, with examples.

Korean learners often have the same experience. They master Hangul and read every letter carefully, yet Koreans struggle to understand them — or Koreans' speech sounds nothing like the letters. "감사합니다" sounds like [감사함니다], "같이" like [가치] and "먹어요" like [머거요].

That's because Korean has pronunciation rules: sounds change when letters meet. There seem to be a lot of rules, but most are natural phenomena that make speaking easier on the mouth. In this guide we explain the essential rules simply, with examples.

First: the seven final-consonant sounds

Many letters can appear as a final consonant (batchim) in Korean, but only seven sounds are actually pronounced. These are the "representative sounds" of final consonants.

SoundFinal lettersExamples
[ㄱ] (k)ㄱ, ㅋ, ㄲ부엌 → [부억], 밖 → [박]
[ㄴ] (n)ㄴ산 → [산]
[ㄷ] (t)ㄷ, ㅌ, ㅅ, ㅆ, ㅈ, ㅊ, ㅎ옷 → [옫], 낮 → [낟], 꽃 → [꼳], 있다 → [읻따]
[ㄹ] (l)ㄹ물 → [물]
[ㅁ] (m)ㅁ밤 → [밤]
[ㅂ] (p)ㅂ, ㅍ앞 → [압], 잎 → [입]
[ㅇ] (ng)ㅇ강 → [강]

So 옷, 옻 and 옫 all sound the same: [옫]. Final consonants end short, as if blocked inside the mouth. It's important not to add a vowel after them as English speakers tend to ("o-teu").

Double final consonants

When two consonants appear as a final (a double batchim), usually only one is pronounced.

  • Reading the first: 넋 → [넉], 앉다 → [안따], 여덟 → [여덜], 값 → [갑]
  • Reading the second: 닭 → [닥], 삶 → [삼], 읊다 → [읍따]

When a vowel follows a double final, both consonants come alive: 닭이 → [달기], 앉아 → [안자].

1. Linking: the final consonant moves to the next syllable

The most basic and frequent rule. When a syllable starting with a vowel (written with ㅇ) follows a final consonant, the final moves over to become the first sound of the next syllable.

WrittenPronounced
먹어요 (I eat)[머거요] meo-geo-yo
한국어 (Korean language)[한구거] han-gu-geo
음악 (music)[으막] eu-mak
옷이 (clothes + subject marker)[오시] o-si
읽어요 (I read)[일거요] il-geo-yo

Note: a final ㅇ doesn't move (고양이 → [고양이]), and a final ㅎ disappears before a vowel (좋아요 → [조아요]).

2. Nasalisation: becoming a nasal before ㄴ and ㅁ

When final [ㄱ], [ㄷ] or [ㅂ] sounds are followed by ㄴ or ㅁ, they turn into the nasal sounds [ㅇ], [ㄴ] and [ㅁ] respectively.

ChangeExamples
[ㄱ] → [ㅇ]한국말 → [한궁말], 국물 → [궁물], 작년 → [장년]
[ㄷ] → [ㄴ]거짓말 → [거진말], 옛날 → [옌날], 있는 → [인는]
[ㅂ] → [ㅁ]감사합니다 → [감사함니다], 입니다 → [임니다], 십만 → [심만]

Every word ending in -ㅂ니다, such as 감사합니다 ("thank you") and 안녕하십니까 ("hello", formal), follows this rule, so practise saying [-ㅁ니다] from the start.

Nasalisation of ㄹ

After a final ㅁ or ㅇ, ㄹ becomes [ㄴ]: 심리 → [심니], 정류장 → [정뉴장], 종로 → [종노]. After final [ㄱ] or [ㅂ], ㄹ becomes [ㄴ] and then the preceding final nasalises too: 독립 → [동닙], 협력 → [혐녁].

3. Liquidisation: ㄴ meets ㄹ and becomes ㄹ

When ㄴ and ㄹ meet, ㄴ turns into [ㄹ] and both are pronounced [ㄹㄹ], whichever comes first.

  • 신라 (Silla) → [실라]
  • 연락 (contact) → [열락]
  • 설날 (Lunar New Year) → [설랄]
  • 한류 (Korean Wave) → [할류]
  • 편리 (convenience) → [펼리]

[ㄹㄹ] is pronounced with the tongue tip against the upper gums, held like a long "l".

4. Tensing: becoming a tense consonant

When final [ㄱ], [ㄷ] or [ㅂ] sounds are followed by ㄱ, ㄷ, ㅂ, ㅅ or ㅈ, the following consonant becomes tense (ㄲ, ㄸ, ㅃ, ㅆ, ㅉ).

WrittenPronounced
학교 (school)[학꾜]
식당 (restaurant)[식땅]
잡지 (magazine)[잡찌]
약속 (promise/appointment)[약쏙]
듣다 (to listen)[듣따]
숙제 (homework)[숙쩨]

Tensing also occurs in some compounds and particular words: 물고기 → [물꼬기], 할 수 있다 → [할 쑤 읻따], 문법 → [문뻡]. It's best to learn these one by one by ear.

5. Aspiration: merging with ㅎ into an aspirated sound

When ㅎ meets ㄱ, ㄷ, ㅂ or ㅈ, the two merge into an aspirated consonant (ㅋ, ㅌ, ㅍ, ㅊ), whichever comes first.

WrittenPronounced
축하 (congratulations)[추카]
좋다 (to be good)[조타]
입학 (school admission)[이팍]
많지 (a lot, isn't it)[만치]
못하다 (to be unable)[모타다]
급하다 (to be urgent)[그파다]

"생일 축하해요" ("happy birthday") is pronounced [생일 추카해요]. It's a common phrase, so be sure to learn it.

6. Palatalisation: ㄷ and ㅌ become ㅈ and ㅊ

When the vowel 이 follows a final ㄷ or ㅌ, they become [ㅈ] and [ㅊ] and move to the next syllable.

  • 같이 (together) → [가치]
  • 굳이 (insistently) → [구지]
  • 해돋이 (sunrise) → [해도지]
  • 밭이 (field + subject marker) → [바치]
  • 닫히다 (to be closed) → [다치다] (ㄷ + ㅎ → ㅌ → ㅊ)

"같이 가요" ("let's go together") sounds like [가치 가요], so practise until you recognise it naturally in conversation.

7. Dropping and weakening ㅎ

A final ㅎ followed by a vowel isn't pronounced.

  • 좋아요 (I like it) → [조아요]
  • 놓아 (put down) → [노아]
  • 싫어요 (I don't like it) → [시러요]
  • 많이 (a lot) → [마니]

In everyday speech, ㅎ between ㄴ, ㄹ, ㅁ or ㅇ and a vowel is often weakened or barely heard: 전화 (phone) sounds close to [저놔], 결혼 (marriage) close to [겨론], 영화 (film) close to [영와]. Pronouncing ㅎ clearly isn't wrong, but knowing this helps you understand native speakers.

8. ㄴ insertion

In compounds or across two words, when the first ends in a consonant and the second starts with 이, 야, 여, 요 or 유, an extra [ㄴ] sound is sometimes added.

  • 색연필 (coloured pencil) → [생년필]
  • 한여름 (midsummer) → [한녀름]
  • 무슨 일 (what's the matter) → [무슨 닐]
  • 서울역 (Seoul Station) → [서울녁] → [서울력] (ㄴ insertion, then liquidisation)

This doesn't happen in every word, so focus on learning it in common words.

How to learn pronunciation rules

  • Learn words, not rule names: learning the real pronunciation of common words and phrases by ear — 감사합니다, 축하해요, 같이 가요, 한국어 — is far more effective than memorising rule names.
  • Check dictionary pronunciations: many Korean dictionaries show the actual pronunciation in brackets next to each word and offer audio.
  • Shadowing: listen to short sentences from dramas or news and repeat them exactly. The rules will come naturally to your mouth.
  • Record and compare: recording yourself and comparing with a native speaker makes differences clear.
  • Dictation: writing down what you hear makes you aware of exactly where sound and spelling differ.
  • Don't aim for perfection: you'll usually be understood even without following every rule. Learn common expressions one at a time.

Frequently asked questions

Do I need to memorise every rule?

Not from the start. Learn frequent rules such as linking, nasalisation, tensing and aspiration first, and pick up the rest naturally as you learn words.

Is reading letter by letter wrong?

Your meaning usually gets across, but it can sound unnatural or be hard to understand. Knowing the rules helps your listening enormously in particular.

Are there exceptions?

Yes. Some words are pronounced differently from the rules, and there's variation by region and speaker. When in doubt, check the dictionary pronunciation.

Final thoughts

Pronunciation rules look complicated at first, but they're really the natural flow Koreans have created to speak comfortably. Once you know them, words that were hard to catch because they didn't match the spelling start to come through one by one.

Today, start by saying three phrases aloud: 감사합니다 [감사함니다], 축하해요 [추카해요] and 같이 가요 [가치 가요]. One small rule that becomes second nature will make your Korean sound much more natural.
