-(으)ㄴ/는데도 vs -지만: What Is the Difference?

What you'll learn

• Choose between a surprising contrast and a neutral contrast in one sentence.
• Attach both endings to verbs, adjectives and nouns, in the present and in the past.
• Use -지만 as a polite softener and explain why -(으)ㄴ/는데도 cannot do that.
• Fix the most common mistakes: using -는데도 for an unsurprising contrast and for adjectives.

Before you start: you should know the polite ending -아요/-어요, the past tense and the pattern -(으)ㄴ/는데 ("and", "but"). The full rules for each ending are in the lessons on -(으)ㄴ/는데도 and -지만. It plays only when you press a button.

What Is the Difference between -(으)ㄴ/는데도 and -지만?

The difference is expectation. -지만 contrasts two facts and does not say whether the result was expected. -(으)ㄴ/는데도 adds that the result goes against what the first fact would lead you to expect. The listener hears surprise, complaint or emphasis.

Two sentences built on the same clause show the contrast:

• 공부했는데도 모르겠어요. (gongbuhaenneundedo moreugesseoyo.) [공부핸는데도 모르게써요] = "Even though I studied, I don't understand." The first fact (studying) should have produced the opposite result, so the speaker is surprised.
• 공부했지만 어려워요. (gongbuhaetjiman eoryeowoyo.) [공부핻찌만 어려워요] = "I studied, but it's hard." The speaker reports two facts. Nothing in the sentence says that the difficulty was unexpected.

The clause 공부했- is the same in both sentences. Only the connective changes the feeling. The next sections turn this into a rule you can apply in a few seconds.

The One-Line Rule

Use -(으)ㄴ/는데도 when you can add "surprisingly" or "you would expect the opposite". Use -지만 when you only place two facts side by side, or when you soften a request. If both fit, -지만 is the safer, plainer choice.

-(으)ㄴ/는데도 vs -지만: Side-by-Side Table

The table compares the two connectives on the points learners need most. Each row has one specific answer for each ending.

The table shows that the two connectives are built differently but attach to the same word classes. The real split is meaning: surprise against neutral contrast. Each connective has a cluster of typical situations.

When Do You Use -(으)ㄴ/는데도?

Use -(으)ㄴ/는데도 when you want to say "and yet". It has three typical jobs:

1. A result that defies the cause. 돈이 없는데도 비싼 가방을 샀어요. (doni eomneundedo bissan gabangeul sasseoyo.) [도니 엄는데도] = "Even though I had no money, I bought an expensive bag."
2. A complaint. 비싼데도 사람이 많아요. (bissandedo sarami manayo.) = "Even though it's expensive, there are many people." The speaker may be amazed or annoyed.
3. A past surprise. 추웠는데도 반바지를 입었어요. (chuwonneundedo banbajireul ibeosseoyo.) [추원는데도] = "Even though it was cold, I wore shorts."

To build the connective, take the right form of the stem. After a verb or after 있다/없다, add 는데도: 가는데도, 먹는데도, 있는데도, 없는데도. After an adjective, add -(으)ㄴ데도: 비싼데도 (ending in a vowel adds ㄴ), 좋은데도 (ending in a consonant adds 은). After a noun, add 인데도: 학생인데도. For the past, add -았/었 first and use -는데도 for every word class: 비쌌는데도, 갔는데도.

The connective -(으)ㄴ/는데도 is built from -(으)ㄴ/는데 plus the particle 도 ("even"). That is why the shorter -(으)ㄴ/는데 can also carry the same idea (공부했는데 모르겠어요), but with less emphasis.

When Do You Use -지만?

Use -지만 when the two clauses are just in contrast. Four situations cover most uses:

1. Two opposing facts. 비싸지만 맛있어요. (bissajiman masisseoyo.) = "It's expensive, but it's delicious."
2. Two different subjects. 저는 커피를 좋아하지만 동생은 차를 좋아해요. (jeoneun keopireul joahajiman dongsaengeun chareul joahaeyo.) = "I like coffee, but my younger sibling likes tea." There is nothing unexpected here, so -(으)ㄴ/는데도 would sound odd.
3. A polite softener. 죄송하지만 창문 좀 닫아 주세요. (joesonghajiman changmun jom dada juseyo.) = "Sorry to bother you, but please close the window."
4. A concession in writing. 작지만 편해요 and similar forms appear in descriptions and reviews.

The form is simple: take the stem and add 지만. Nothing changes after a vowel, a consonant or ㄹ. The past tense goes on the stem, as in 공부했지만 and 비쌌지만. The pronunciation follows the stem: 어렵지만 is [어렵찌만] and 좋지만 is [조치만].

The softener use is the clearest difference. 죄송하지만 introduces a request and does not contrast anything. 죄송한데도 would mean "even though I'm sorry", which makes a different and unwelcome sentence.

Worked Example: Choosing between the Two

Follow the steps with the idea "I like coffee. My sibling likes tea."

1. Write the two facts. 저는 커피를 좋아해요. 동생은 차를 좋아해요.
2. Ask: is the second fact surprising because of the first? No. A taste for tea does not conflict with a taste for coffee, because the two people are different.
3. Choose -지만. Attach it to the stem 좋아하: 좋아하지만. The sentence becomes 저는 커피를 좋아하지만 동생은 차를 좋아해요.
4. Test with a new idea. "It was cold, but I wore shorts." Here the second fact defies the first. Use -(으)ㄴ/는데도 on the past stem 추웠: 추웠는데도 반바지를 입었어요.

You will know it worked when you can say "surprisingly" in step 4 and cannot in step 3. The usual slip at this stage is to use -(으)ㄴ/는데도 for every contrast because it feels more advanced. A neutral contrast with -(으)ㄴ/는데도 sounds like a complaint.

Can You Use Both in the Same Situation?

Yes, when the second fact really is unexpected, either one is grammatical. 공부했지만 모르겠어요 and 공부했는데도 모르겠어요 are both correct. The first reports the facts. The second adds emotion.

Some limits are firm. Only -지만 works as a softener or between two unrelated subjects. Only -(으)ㄴ/는데도 adds surprise without another word. Spoken Korean can also use a sentence starter to add the same feeling: 그런데도 계속 기다렸어요. (geureondedo gyesok gidaryeosseoyo.) = "Even so, I kept waiting." The starter 그런데도 means "even so", and 하지만 is the sentence-starting form of -지만 ("but").

An honest limit: this page treats the textbook split between the two. In real speech, speakers choose -지만 for a calm tone and -(으)ㄴ/는데도 for a stronger one, and the line is blurry. The pair -(으)ㄴ/는데 and -지만 has its own page, -(으)ㄴ/는데 vs -지만.

Which Should You Pick? a Simple Rule of Thumb

Follow these four steps in order. The first step that applies gives the answer.

1. Are you softening a request or an opinion? Use -지만: 죄송하지만, 실례지만.
2. Do the two clauses have different subjects with no cause-and-effect link? Use -지만: 저는 커피를 좋아하지만 동생은 차를 좋아해요.
3. Does the second clause go against what the first one leads you to expect? Use -(으)ㄴ/는데도: 추웠는데도 반바지를 입었어요.
4. Is it a plain contrast with no surprise? Use -지만: 작지만 편해요.

Checkpoint: read the sentence with "surprisingly" in English. If it still makes sense, -(으)ㄴ/는데도 is right. If it sounds strange, choose -지만.

What Mistakes Do Learners Make with These Two?

Learners most often use -(으)ㄴ/는데도 where no surprise exists. Five mistakes appear again and again, and each has a quick repair.

1. Using -(으)ㄴ/는데도 for a neutral contrast. Learners often assume that it is a stronger "but". Actually, 저는 커피를 좋아하는데도 동생은 차를 좋아해요 sounds as if the sibling should not like tea. Say 좋아하지만.
2. Using -는데도 after an adjective. 비싸는데도 is wrong. Use 비싼데도, with the adjective form -(으)ㄴ.
3. Using -(으)ㄴ/는데도 for a request. 죄송한데도 창문 좀 닫아 주세요 is wrong. Use 죄송하지만.
4. Mixing up 도 and the hypothetical. 비가 와도 means "even if it rains" and may not be true. 비가 오는데도 means "even though it is raining" and is true now. Choose the second only for real facts.
5. Forgetting the past form on adjectives. For a past adjective, say 비쌌는데도, not 비싼데도. The form 비싼데도 describes the present.

An honest limit: -(으)ㄴ/는데도 usually needs a main clause that states a result, and commands or suggestions after it sound unnatural. If you want to give advice after a contrast, use -지만 or start a new sentence.

Practice: Choose the Right Pattern

Try the five items before you read the answer key. Cover the answers with your hand.

1. Choose. You politely ask for help. Complete: ___ 창문 좀 열어 주세요. (죄송하지만 / 죄송한데도)
2. Choose. Two different tastes. Complete: 저는 커피를 좋아하___ 동생은 차를 좋아해요. (지만 / 는데도)
3. Choose. Something is expensive, yet crowded. Complete: ___ 사람이 많아요. (비싸지만 / 비싼데도)
4. Fix the error. Correct 비싸는데도 사람이 많아요.
5. Choose. A plain contrast. Complete: 작___ 편해요. (지만 / 은데도)

Answer key

1. 죄송하지만. A softener before a request uses -지만.
2. 지만. The two tastes are unrelated, and nothing is surprising.
3. 비싼데도. The crowd is unexpected given the high price, so -(으)ㄴ/는데도 fits. 비싸지만 is also grammatical but loses the surprise.
4. 비싼데도 사람이 많아요. An adjective takes -(으)ㄴ데도, not -는데도.
5. 지만. 작지만 편해요 is a plain contrast between two properties.

If you got four or five right, you can use both connectives confidently. If you missed item 3, reread the section on surprise and the "surprisingly" test.

What Should You Learn Next?

After -(으)ㄴ/는데도 vs -지만, study each connective on its own, then the neighbouring contrasts. This page compares the two connectives but does not teach every use of either one.

1. Read the full lessons: -(으)ㄴ/는데도 and -지만.
2. Compare the shorter connective with -지만 in -(으)ㄴ/는데 vs -지만.
3. Learn the hypothetical "even if" in -아/어도.
4. See every pair on Confusing Grammar Compared, or browse Intermediate Grammar for the patterns around level B1.

With these steps, the choice in -(으)ㄴ/는데도 vs -지만 becomes automatic: ask whether the result is surprising, then add the connective to the stem.

Frequently Asked Questions

Can I always replace -(으)ㄴ/는데도 with -지만?

Grammatically, usually yes, but you lose the surprise. 공부했지만 모르겠어요 only reports two facts. 공부했는데도 모르겠어요 adds "and that is unexpected". The reverse does not work: 죄송하지만 and a neutral contrast such as 작지만 편해요 cannot be rewritten with -(으)ㄴ/는데도.

Which one sounds more natural in speech?

-지만 is the more frequent pattern, because everyday contrast is usually neutral. -(으)ㄴ/는데도 is natural when you complain, show surprise or stress that something should have gone differently. Spoken Korean also uses the shorter -(으)ㄴ/는데 for the same idea, with less emphasis.

How do I attach -(으)ㄴ/는데도 to different word types?

After action verbs and 있다/없다, use -는데도: 가는데도, 있는데도. After adjectives, use -(으)ㄴ데도: 비싼데도, 좋은데도. After nouns, use 인데도: 학생인데도. For the past, add -았/었 first and then -는데도 for every type: 비쌌는데도, 갔는데도.

How is -(으)ㄴ/는데도 different from -아/어도?

-아/어도 means "even if" and can be hypothetical: 비가 와도 갈 거예요 ("I will go even if it rains"). -(으)ㄴ/는데도 reports something that is happening or has happened: 비가 오는데도 갔어요 ("I went even though it was raining"). The second kind of sentence is always about a real fact.

What is the quickest rule to remember?

Test the sentence with "surprisingly". If "surprisingly" fits, use -(으)ㄴ/는데도. If it only places two facts side by side, or if you are softening a request, use -지만. When unsure, -지만 is the safer choice because it makes no claim about expectation.
