Grammar: -던데요
Sharing Something You Noticed
Use -던데요 when you share something you personally saw, heard, or experienced before speaking. It often leaves room for the listener to respond. Depending on the situation, you might use it to share an observation, give your impression, or gently raise a question.
Attach -던데요 to a verb or adjective stem: 가다 → 가던데요, 좋다 → 좋던데요. To emphasize that an event was already completed, you can use -았/었/했던데요, as in 닫았다 → 닫았던데요.
The English translation depends on the context. A sentence with -던데요 may sound like “I noticed…” or “I thought…” rather than a simple statement of fact.
Example Sentences
이 건물 앞에 경찰차들이 있던데요?
I noticed police cars in front of this building. Do you know what happened?
친구가 새 TV를 샀는데 화질이 진짜 좋던데요!
My friend bought a new TV, and I thought the picture quality was really good!
In the first example, the speaker shares something they saw and invites an explanation. In the second, the speaker shares an impression based on seeing the TV.
