- -아/어도: corresponds to “even if” or “although”

3. Meaning & Usage
1. Factual vs. Hypothetical Contrast
- ‘-(으)ㄴ/는데도’ is used when the first clause describes a real, completed, or factual situation, and the second clause shows an unexpected or contrasting result.
- ‘-아/어도’ is used when the first clause presents a hypothetical or possible condition, and the second clause shows that the result does not change regardless of that condition.
Examples:
- 비가 왔는데도 우산을 안 썼어요. (Even though it rained, I didn’t use an umbrella.)
- 많이 먹었는데도 배가 고팠어요. (Even though I ate a lot, I was still hungry.)

- 배가 고파도 참을 수 있어요. (Even if I’m hungry, I can endure it.)
- 열심히 공부해도 성적이 나쁠 수 있어요. (Even if you study hard, your grades might be bad.)
2. Completed Actions vs. Neutral Conditions
- ‘-(으)ㄴ/는데도’ often implies surprise or frustration over a completed action that didn’t lead to the expected result.
- ‘-아/어도’ implies calm acceptance or continuation regardless of a condition.
Examples:
- 약을 먹었는데도 안 나았어요. (Even though I took medicine, I didn’t get better.)
- 전화했는데도 안 받았어요. (Even though I called, they didn’t answer.)

- 조심해도 실수할 수 있어요. (Even if you’re careful, you can still make mistakes.)
3. Identity or Status-Based Contrast
- Use ‘-(이)ㄴ데도’ when the subject’s role or identity is contrasted with an unexpected result.
- Use ‘-아/어도’ when the subject’s role is less emphasized or hypothetical.
Examples:
- 선생님인데도 숙제를 깜빡하셨어요. (Even though he is a teacher, he forgot the homework.)
- 의사인데도 병을 못 고쳤어요. (Even though she’s a doctor, she couldn’t cure the illness.)

4. Emotional Tone: Surprise vs. Acceptance
- ‘-(으)ㄴ/는데도’ often carries an emotional tone of disbelief, complaint, or frustration.
- ‘-아/어도’ is more neutral or accepting, especially in polite conversation.
Examples:
