Lesson 9

Nasalization (비음화)

Stop consonants ㄱ, ㄷ, ㅂ become nasal ㅇ, ㄴ, ㅁ before nasal consonants ㄴ or ㅁ.

비음화 — Nasalization Rule

When ㄱ, ㄷ, or ㅂ is followed by a nasal consonant ㄴ or ㅁ, the stop consonant changes to the corresponding nasal: ㄱ→ㅇ, ㄷ→ㄴ, ㅂ→ㅁ.

국물 → [궁물]gungmul국[guk] + 물[mul] → ㄱ before ㅁ → ㅇ: [gung-mul]
입니다 → [임니다]imnida입[ip] + 니다[nida] → ㅂ before ㄴ → ㅁ: [im-ni-da]

비음화 — The Three Pairs

Remember these three pairs: ㄱ(g/k) → ㅇ(ng), ㄷ(d/t) → ㄴ(n), ㅂ(b/p) → ㅁ(m). All three become the nasal that shares the same place of articulation in the mouth.

박물관 → [방물관]bangmulgwan박[bak] + 물관 → ㄱ before ㅁ → ㅇ: [bang-mul-gwan]
한국말 → [한궁말]hangungmal한국[hanguk] + 말[mal] → ㄱ before ㅁ → ㅇ: [han-gung-mal]
