ㄱ, ㄲ, ㅋ + ㄴ, ㅁ
- Case 1: 'ㄱ' 받침 + 'ㄴ' or 'ㅁ' → ㄱ gets pronounced as ㅇ(/ŋ/)
- Case 2: 'ㄲ' 받침 + 'ㄴ' or 'ㅁ' → ㄲ gets pronounced as ㅇ(/ŋ/)
- Case 3: 'ㅋ' 받침 + 'ㄴ' or 'ㅁ' → ㅋ gets pronounced as ㅇ(/ŋ/)
In the 받침 position, ㄱ, ㄲ, and ㅋ all make the same sound, and when followed by a nasal sound ㅁ(/m/) or ㄴ(/n/), the ㄱ sound must also match the nasal sound and becomes an ㅇ (/ŋ/) nasal sound. Note that when ㄱ also appears in the double 받침 position, such as 읽다, that this rule applies as well. This rule also applies when the ㄱ is a 받침 and the next word's first letter is a nasal sound, i.e. "부엌 문."
