(으)ㄴ 적이 있다
Verb+(으)ㄴ 적이 있다 : This pattern is equivalent to the phrase 'to have ~ before' and can also in the question form can mean 'have you ever ~ ?' It is often combined with the form V+어/아/여 보다 to ask someone if they've ever tried something. The opposite pattern is V+(으)ㄴ 적이 없다.
Note that this construction expresses past tense through verb + (으)ㄴ. There is no need to change the main verb 있다/없다 to its past tense form.
- 보다 → 본 걱이 있다
