KOREAN QUESTIONS ~나(요)

Using ~나(요) at the end of a sentence to ask a question has the same function of ~ㄴ/은가(요). That is, it can be used to make a question sound slightly softer than the other ways to ask a question. However, ~나(요) is more often used with verbs and with 있다 and 없다. For example:

Notice that the ㄹ irregular needs to be applied in appropriate situations again:

밥이 있나? - Is there rice?
사과도 여기서 파나요? - Do you sell apples here too?
소녀시대 콘서트를 여기서 하나요? - Is the Girl's Generation concert here?

This form can be used in the past tense as well. For example:

교통카드가 있었나요? - Did you have your bus (transportation) card?
그 소식을 들었나요? - Did you hear that/the news?
만화책을 샀나요? - Did you buy the comic book?

It is possible to use this in the future tense, but it only sounds natural when applying it to the ~겠다 future conjugation. Adding ~나(요) to 이다 is typically not done, and therefore adding it to words that are conjugating using ~ㄹ/을 것이다 is unnatural. For example:

내일 퇴원할 거나요? – unnatural
내일 퇴원할 것이나요? – unnatural
