-냐

V/Adj/이다, 아니다 + 냐 This indicates that the sentence is a question and informal. It can only be used with very close friends or younger people.

어디 가냐?

Where are you going?

좋냐?

Is it good?

내가 네 친구냐?

Am I your friend? (sarcastic, joke)

• You can also use '-니', which gives a less authoritative and more friendly feeling when asking questions, while -냐 is considered too familiar and often sounds sarcastic, rude, or leaves a sassy impression.

어디 가니? Where are you going?

좋니? Is it good?

• Technically, for verbs, we use -느냐고, and for adjectives, we use -(으)냐고. However, most of the time, -느냐고 and -(으)냐고 are simply replaced with -냐고. (That's why I organized the table as shown above.)

verb 가다 → 가느냐고, 가냐고

verb 먹다 → 먹느냐고, 먹냐고

adj 예쁘다 → 예쁘냐고

adj 좋다 → 좋으냐고, 좋냐고
