Learn Korean: State Verb + 걸 알다

Let’s take a look at the Korean sentence pattern State Verb + 걸 알다. We use this to express that we know something. That that-clause contains a state verb.

Example #1: I know that I am pretty. The main verb is 예쁘다 (to be pretty). We take the verb stem and attach ㄴ 걸 because it ends in a vowel. Then, we add 알다. The actual sentence is 예쁜 걸 알아(요). 걸 is simplified into 거 when speaking.

Example #1: I know that I am short. The main verb is 키가 작다 (to be short). We take the verb stem and attach 은 걸 because it ends in a consonant. Then, we add 알다. The actual sentence is 키가 작은 걸 알아(요).
