Have Done Before

Express whether you have experienced something: Formation: • Consonant stems + 은 적이: 먹다 → 먹은 적이 • Vowel stems + ㄴ 적이: 가다 → 간 적이 • ㄹ stems: drop ㄹ + ㄴ 적이: 만들다 → 만든 적이 Usage: • -(으)ㄴ 적이 있다 = have done before • -(으)ㄴ 적이 없다 = have never done 적 means "time" or "occasion" Literally: "There is/isn't a time when I..." More emphatic than -아/어 봤다: • 가 본 적이 있어요 = I have been there (emphasizes the experience) • 가 봤어요 = I've been there (simple past experience)
