48: Korean Pronunciation Rule 3: Aspiration (격음화)

Learn Korean for Free | Beginner Korean Grammar #48

좋다 is pronounced [조타], and 축하 is pronounced [추카]. In these words, ㅎ combines with a neighboring consonant and creates an aspirated sound.

What Does 발음 규칙 3. 격음화 Mean?

격음화, or aspiration, occurs when ㅎ meets ㄱ, ㄷ, ㅂ, or ㅈ in certain positions. The combined pronunciation becomes ㅋ, ㅌ, ㅍ, or ㅊ.

The Rule

ㄱ + ㅎ → ㅋ: 축하 [추카]. ㄷ/ㅅ-like final + ㅎ or ㅎ + ㄷ → ㅌ: 좋다 [조타]. ㅂ + ㅎ → ㅍ: 입학 [이팍]. ㅈ + ㅎ → ㅊ: 잡히다 [자피다] follows the ㅂ+ㅎ pattern, while 놓지 [노치] shows ㅎ+ㅈ. Focus on the complete examples.
