축하[추카]

Aspiration

When ㅎ meets ㄱ, ㄷ, ㅂ, or ㅈ, the two merge into the aspirated sounds ㅋ, ㅌ, ㅍ, ㅊ. That is why 축하 (congratulations) is pronounced [추카].

Pattern

ㅎ + ㄱ/ㄷ/ㅂ/ㅈ (또는 반대 순서) → 거센소리 ㅋ/ㅌ/ㅍ/ㅊ

How It Works

The breathy energy of ㅎ fuses with the neighboring plain consonant into a single aspirated sound. Order does not matter: ㄱ+ㅎ=[k], ㄷ+ㅎ=[t], ㅂ+ㅎ=[p], ㅈ+ㅎ=[ch] (all aspirated).
