Korean "Ghost Sounds": Why Pronunciation Changes

The Mystery of Changing Sounds

When you start listening to Korean, you quickly notice letters don't always sound as expected. 감사합니다 isn't pronounced "gam-sa-hap-ni-da" but "gam-sa-ham-ni-da". Why?

It's because of linking rules — automatic phonetic transformations.

The 5 Main Rules

1. Nasalization

When a final obstruent (ㅂ, ㄱ, ㄷ) precedes ㄴ or ㅁ:

• ㅂ → ㅁ: 합니다 → 함니다
• ㄱ → ㅇ: 학년 → 항년

2. Linking

When a word ends with a consonant and the next starts with ㅇ (silent), the consonant slides over:

• 한국어 → 한구거 (hangugeo)

3. Aspiration

When ㅎ meets ㄱ, ㄷ, ㅂ, ㅈ, they merge into aspirated versions:

• 축하 → 추카 (chuka)

4. Palatalization

ㄷ/ㅌ become ㅈ/ㅊ before 이:

• 같이 → 가치 (gachi)

5. Fortification (Tensification)

After certain final consonants, the next consonant doubles:

• 학교 → 학꾜 (hakkyo)

💡 Good news: your brain learns these rules naturally from listening to Korean (K-pop, dramas).
