Overview
V+다니/라니/냐니/자니 is a versatile grammatical construction used to express the speaker's reaction to a piece of information they have just heard, read, or realized. This reaction can range from surprise, disbelief, wonder, indignation, or even a rhetorical question. It essentially means "To think that [X]..." or "I can't believe that [X]...", indicating an emotional response to the content of the preceding clause.
Usage
This expression is primarily used to convey a strong emotional response to a statement, question, command, or suggestion. It is often used when the speaker is processing new information and expressing their immediate feelings about it. The specific form used depends on the type of sentence being reacted to:
- -다니: Used with declarative statements (verbs, adjectives, 있다/없다, past/future tense). It expresses surprise or disbelief about a fact. For example, "그가 한국어를 잘하다니 놀랍다!" (To think that he speaks Korean well, it's surprising!)
- -라니: Used with nouns (N+(이)라니) and imperative verbs (V+(으)라니). With nouns, it expresses surprise about something being a certain noun (e.g., "그게 거짓말이라니!"). With imperative verbs, it expresses surprise or disbelief that someone gave a command (e.g., "나보고 혼자 가라니?").
- -냐니: Used with interrogative statements (verbs, adjectives, nouns). It expresses surprise or disbelief at a question being asked or at the content of a question. It often functions as a rhetorical question itself (e.g., "벌써 끝났냐니?").
- -자니: Used with propositive statements (V+자니). It expresses surprise or disbelief at a suggestion being made (e.g., "지금 가자니?"). This form is less common for pure reaction and sometimes overlaps with -다니 when reacting to the fact of a suggestion.
This structure can stand alone as an exclamation or introduce a longer sentence explaining the reaction.

Knowledge Plus
- Origin: This grammar point is derived from indirect quotation forms (e.g., ~다고 하다, ~라고 하다, ~냐고 하다, ~자고 하다) combined with the reason/cause ending ~으니/니까. It literally means "because (I heard/realized) that...", but the meaning has evolved to express a direct emotional reaction.
- Nuance: It carries a stronger emotional weight than simply stating a fact or asking a question. It implies a sense of processing new information and reacting to it, often with a hint of disbelief or astonishment. The reaction can be positive (pleasant surprise) or negative (disbelief, indignation, frustration).
- Context: It's frequently used in spoken Korean and informal writing to express spontaneous reactions. It can also be used rhetorically to question the validity or appropriateness of something.
