The short answer
는데 joins two parts of a sentence. It sets up background (“I went to the market, and...”) or a soft “but”. Use 는데 after verbs and the past, (으)ㄴ데 after adjectives, and 인데 after nouns. At the end of a sentence, 는데요 makes you sound gentle.
Listen to any Korean conversation and you will hear 는데 again and again. It is a small ending that does a lot of work. Think of it as saying “so here’s the situation...” before the main point. If you have read the guide to 지만 (but), this one is its softer, more flexible cousin.
1. The forms: 는데, 은데/ㄴ데, 인데
The shape depends on the kind of word in front of it. An action verb is a doing word, like go or eat. An adjective in Korean is a describing word that works like a verb, like “is expensive” or “is small”.
- Action verbs, 있다, 없다: stem + 는데 (가는데, 먹는데, 맛있는데)
- Adjectives ending in a vowel: stem + ㄴ데 (비싼데, 바쁜데)
- Adjectives ending in a consonant: stem + 은데 (작은데, 좋은데)
- Nouns: noun + 인데 (학생인데, 친구인데)
- Any past tense: 았/었 + 는데 (갔는데, 좋았는데)
| Dictionary form | Present | Past |
|---|---|---|
| 가다 (go) | 가는데 | 갔는데 |
| 먹다 (eat) | 먹는데 | 먹었는데 |
| 살다 (live) | 사는데 | 살았는데 |
| 맛있다 (tasty) | 맛있는데 | 맛있었는데 |
| 비싸다 (expensive) | 비싼데 | 비쌌는데 |
| 작다 (small) | 작은데 | 작았는데 |
| 춥다 (cold) | 추운데 | 추웠는데 |
| 멀다 (far) | 먼데 | 멀었는데 |
| 학생이다 (be a student) | 학생인데 | 학생이었는데 |
| 친구이다 (be a friend) | 친구인데 | 친구였는데 |
Two small surprises: a stem ending in ㄹ drops it (살다 to 사는데, 멀다 to 먼데), and ㅂ adjectives like 춥다 become 추운데.
2. Giving background: “..., and”
This is the most common use. The first half sets the scene. The second half is what you really want to say: a fact, a question or a request. English often uses “and”, “so”, or two separate sentences.
3. A soft “but”
When the two halves pull in different directions, 는데 works as a gentle “but”. It sounds a little softer and more conversational than 지만.
시험을 보다 means to take an exam. 시험을 못 보다 means to do badly on it.
4. Ending with 는데요: soft and open
You can also stop right after 는데 and add 요. The sentence feels unfinished on purpose. It softens what you say and leaves room for the other person to answer. Koreans use it to refuse gently, to point out a problem politely, or to introduce themselves on the phone.
An answer to 'Are you free tomorrow?'. It is a polite way to say no without saying no.
Hear it in songs
Song lyrics and drama lines are full of 는데, especially the trailing 는데 at the end of a line. Open a song in Hanbok Lyrics and tap a line to see every ending explained. Next, compare it with the clear contrast of 지만 (but), or learn to give reasons with 아서/어서 (because) and (으)니까.

Questions learners ask
What does 는데 mean in Korean?
는데 links two parts of a sentence. Most often it gives background ("I went to the market, and...") or a soft contrast ("it is pretty, but..."). It can be translated as "and", "but", "so" or not at all.
When do you use 는데, 은데 and ㄴ데?
Use 는데 after action verbs, after 있다 and 없다, and after any past tense (갔는데). Use 은데 after an adjective stem ending in a consonant (작은데) and ㄴ데 after a vowel (비싼데). After a noun, use 인데 (학생인데).
What does 는데요 mean at the end of a sentence?
Ending with 는데요 leaves the sentence a little open. It softens what you say and invites the other person to react: 내일은 좀 바쁜데요... (I am a bit busy tomorrow...) is a gentle way to say no.
What is the difference between 는데 and 지만?
지만 is a clear "but" that always shows contrast. 는데 is softer and wider: it can be "but", but it is also used just to set the scene before the main point.
