普通形 + んだって (Na/N + なんだって)I heard that... (casual emphasis)
Combines the explanatory 'ん' with hearsay 'だって'. It sounds more conversational and often implies that the information is surprising or interesting.
Common mistakes
- Forgetting to use 'な' for Nouns/Na-adjectives (e.g., 好きなんだった vs 好きなんだって)
- Using it in formal contexts
- Confusing with 'んだよ' (telling someone a fact you know)
