- ‘-느냐’ is primarily used with verbs in formal or written contexts.

3. Meaning & Usage
Each of the question endings ‘-느냐’, ‘-냐’, and ‘-니’ serves a different purpose based on formality, context, and the level of politeness. Here’s a breakdown of their uses:
1. ‘-느냐’ – Formal, Used in Written Korean, Military Speech, and Older Styles of Korean
‘-느냐’ is typically used in formal or written contexts, such as academic writing, official documents, or military speech. It is more likely to be found in older styles of Korean. However, it is important to note that while ‘-느냐’ is formal, it is not appropriate to use it with someone of higher status or authority. For example, a younger person should not use ‘-느냐’ when speaking to an elder or superior. A polite form like ‘-세요?’ would be more appropriate.
Example Sentences:
- 지금 어디로 가느냐? (Where are you going now?)
- 네가 그 책을 읽었느냐? (Did you read that book?)
- 이 문제의 해결책을 알고 있느냐? (Do you know the solution to this problem?)
- 이 문제를 풀었느냐? (Did you solve this problem?)
- 내일 회의에 참석하느냐? (Are you attending the meeting tomorrow?)
2. ‘-냐’ – Casual, Blunt, Often Used Between Close Friends
‘-냐’ is used in casual speech but can sometimes sound blunt, especially if used with someone not closely acquainted. It is commonly used among friends or in direct speech. Just like ‘-느냐’, it is not appropriate to use ‘-냐’ with someone of higher status or authority. For instance, a younger person should avoid using ‘-냐?’ when speaking to elders or superiors, instead opting for a more polite form such as ‘-세요?’ or ‘-습니까?’
Example Sentences:
- 날씨가 왜 이렇게 덥냐? (Why is the weather so hot?)
- 네가 그 영화를 봤냐? (Did you watch that movie?)
- 왜 그렇게 빨리 가냐? (Why are you leaving so soon?)
- 너 어디 가냐? (Where are you going?)
- 언제 끝나냐? (When is it ending?)
3. ‘-니’ – Informal and Friendly, Common in Everyday Speech
‘-니’ is typically used in informal settings, especially among close friends or people of the same age. It’s common in casual conversations and is often used to ask questions in a friendly, familiar manner. However, it’s important to note that it is not appropriate for use when speaking to someone of higher status or authority. For example, a younger sibling should not use ‘-니?’ when speaking to an older sibling. Instead, a more polite form like ‘-세요?’ should be used.
Example Sentences:
- 지금 뭐 하니? (What are you doing now?)
- 숙제를 다 했니? (Did you finish your homework?)
- 친구랑 만나니? (Are you meeting your friend?)
- 영화 재미있니? (Is the movie interesting?)
