~(으)ㄴ/는지 알아?

To ask if someone knows about something or how to do something in general, use ~(으)ㄴ/는지 알아요? or ~(으)ㄴ/는지 몰라요? I would advise you to use this with care because to directly state or ask if someone older than you knows (or doesn't know) about something might come off looking like an asshat so just be careful.

Examples:

언제부터 방학이는지 알죠?
I'm sure you know when is your your school vacation.

한국에서는 대통령이 누구인지 알아요?
Do you know who the President is in Korea?

김치 만드는지 몰라죠?
You don't know how to make kimchi, right?

미국에서는 가장 유명한 배우 누구인지 아세요?
Do you know who is the most famous actor in America?

A: 공립 도서관에서 고서를 어떻게 빌리는지 알아요?
Do you know how to borrow old books from the library?
B: 잘 몰라요. 아마 외국인등록증 주면 빌릴 수가 있을거예요
Not really. Maybe if I give them my Foreign Registration Card...

A: 소현이랑 사귀는 남자가 누구인지 알니?
Do you know who Sohyeon is dating now?
B: 사귄다고? 택규랑 사귀었어? 역시...
What? She's dating? With Tekkyu? I knew it...

A: 로버트 씨가 언제 한국에 왔는지 아세요?
Do you know how long Robert has been in Korea?
B: 네, 알아요. 80년때에 왔어요.
Yeah I know. He came here in the eighties.

I'm so glad I found this blog. Thank you so much for all of your grammar posts, especially this one! I wanted to use ~는지 알아? with my Korean penpal but decided not to, even though she's younger than me. It does sound a bit aggressive in some contexts. I'm looking forward to your future posts. Thanks again!
