Most foreigners who learn “Only” in Korea learn as a 만/man, but there are other ways to say “Only” in Korean. Let’s learn how to use 만 first. To use man, you need to memorize “noun +만” or “ Verb stem+기만 하다”. As you read my blog before, 기 is making Verb to noun. As you may remember, Korean use verb as a nous with 기 a lot. Please read examples below.

먹다 is verb and means to eat, but it becomes a noun if you add 기. 먹기

내 친구가 요리하니까 너는 먹기만 하면 된다/My friend will cook, you only need to eat.

입다/to wear

저 손님은 입기만 하고 안 산다/ That customer only wear clothing without buying it.

나는 감자만 좋아한다/ I only like potato.

그녀만 영어를 합니다/she only speak English.
