-은 적이 있다

-은 적이 있다: Have You Ever — Experience

Have (ever) done — marks that an experience exists (or, with 없다, does not).

Before this, make sure you know: -았-/-었- , 이/가

How to form it

When Form Example
Verb stem ends in a consonant (not ) -은 적이 있다 먹다 → 먹은 적이 있다 / 읽다 → 읽은 적이 있다
Verb stem ends in a vowel or -ㄴ 적이 있다 가다 → 간 적이 있다 / 살다 → 산 적이 있다
Negative experience -은/-ㄴ 적이 없다 한국에 가 본 적이 없어요 / 먹어 본 적이 없어요

-은 적이 있다 is Korean for that has happened (to me) at least once — experience on the record, not a dated story.

휴가를 어떻게 보내기로 했어요? sits in the same unit as plans; this pattern is the have you ever… half of travel small talk.

Experience ≠ simple past

PatternJob
-았-/-었- -었-a past event you are narrating
-은 적이 있다whether such an occasion exists

어제 병원에 갔어요 tells yesterday’s trip. 병원에 간 적이 있어요? asks if hospital-going is in your life history.

With -어 보다

-어 보다 in the past (가 봤어요) is how Koreans often ask have you tried / have you ever. Speech freely combines them: 가 본 적이 있어요. Learn both; do not delete one as a “duplicate English have.”

is a bound noun

우리말샘’s in this use sits after adnominals like -. Particle on 적이 is normal subject marking (이/가) before 있다/없다.

Same unit as decisions

Common questions

Do I put -- before -은 적?

No beginner form like *갔은 적. The adnominal -은/-ㄴ already carries the past/completed flavour before .

How do I say 'never'?

Use 없다: 먹은 적이 없어요. English *never + past* is not a license to invent a different Korean template.

Is it only for questions?

No. 제주도에 간 적이 있어요 states your experience; the question form asks for someone else's.

Adjective experience?

Classroom focus is action verbs. Do not freely build *예쁜 적이 있다 without models you have actually heard.
