The Art of the Korean Rebuttal: -건만, -기로서니, -으련마는
Concede, then counter. -건만 grants a point yet pushes back (노력했건만, 결과는 달랐다 — I tried hard, yet the result differed), -기로서니 says even granting X that is no excuse (아무리 급하기로서니 거짓말을 하다니 — however urgent it was, lying is no excuse), and -으련마는 voices the wistful would-be (있으련마는 — there surely would be, but…).

A strong rebuttal concedes before it counters, and Korean has three formal tools for it. -건만 grants a point yet pushes back (그렇게 노력했건만, 결과는 달랐다 — I tried that hard, yet the result was different), -기로서니 admits a circumstance only to deny it as an excuse (아무리 급하기로서니 거짓말은 안 되지 — however urgent it was, lying is no excuse), and -으련마는 voices the wistful would-be (조금만 빨랐으면 됐으련마는 — a bit faster and it would have worked, but…). This is Chapter 2’s craft of disagreement — how to grant your opponent something and still win the point.
You learned to open an argument in the debate thesis lesson; now we learn to answer one. A good rebuttal never just denies — it concedes fairly, then turns. Start with the words you need to take an argument apart.
Ten words for rebutting
Grant it, yet push back: -건만
Attach -건만 to a finite stem to concede a fact and then turn against it — ‘X is/was so, and yet —.’ It is the formal, faintly frustrated sibling of -지만, made for written argument.
그렇게 노력했건만, 결과는 달라지지 않았다 = I tried that hard, yet the result did not change 자료는 풍부하건만, 정작 핵심을 비껴간다 = the data is plentiful, yet it misses the very point 여러 번 설명했건만, 그는 듣지 않았다 = I explained it several times, yet he would not listen 근거는 그럴듯하건만, 전제부터 틀렸다 = the grounds seem plausible, yet the premise is wrong
The feeling is contrast that stings: the effort or merit in the first clause came to nothing. In rebuttal, -건만 lets you honor the opponent’s work before showing it still fails.
Even granting that — no excuse: -기로서니
Attach -기로서니 to a stem to concede a circumstance only to deny that it justifies what followed. It almost always pairs with 아무리 (‘however much’) and lands on a ‘still, you mustn’t’ verdict.
아무리 급하기로서니 거짓말까지 할 필요는 없었다 = however urgent it was, there was no need to lie 아무리 화가 나기로서니 그런 말을 하면 안 되지 = however angry you were, you shouldn’t say such a thing 아무리 바쁘기로서니 약속을 잊다니 = however busy you were, forgetting the promise (is too much) 아무리 이익이 크기로서니 원칙을 버릴 수는 없다 = however large the profit, we can’t abandon principle
Unlike -더라도 (‘even if’), which just allows a hypothetical, -기로서니 actively rejects an excuse already on the table: yes, it was urgent — but that does not license the lie. It is a precision rebuttal move.
The wistful would-be: -으련마는
Attach -으련마는 to a stem to voice a likely outcome together with regret that it didn’t, or won’t, come true — ‘it surely would be X, but —.’ The trailing 마는 carries the sigh.
조금만 일찍 왔으면 자리가 있으련마는 = if only they’d come a bit earlier there surely would be seats, but… 근거만 탄탄했으면 통했으련마는 = if only the grounds were solid it would have worked, but… 말로는 쉬우련마는, 실천이 어렵다 = in words it would be easy, but the practice is hard 사정을 알면 이해하련마는, 그러기엔 너무 늦었다 = knowing the situation they’d understand, but it’s too late for that
A plain -겠- only estimates (자리가 있겠다 = there are probably seats). -으련마는 estimates and mourns the gap with reality, leaving the disappointing facts implied — a graceful way to concede and counter in one breath.
A rebuttal, written out
Here is the concede-then-counter rhythm in formal prose — answering an opponent who blames a failure on a tight deadline:
상대측은 자료를 충분히 모았다고 말한다. 분명 풍부하건만, 정작 핵심 쟁점은 비껴가 있다. 시간이 촉박했다는 변명도 있었다. 그러나 아무리 급하기로서니, 검증을 통째로 건너뛴 것까지 정당화되지는 않는다. 조금만 더 신중했으면 이런 허점은 없으련마는, 결국 결론은 전제부터 흔들리고 만다.
The other side claims they gathered enough data. It is certainly plentiful — yet it sidesteps the very crux. There was also the excuse that time was tight. But however urgent it was, that does not justify skipping verification altogether. A little more caution and there surely would have been no such loophole — but in the end the conclusion crumbles from the premise up.
Trading rebuttals before the round
The same forms, now in a quick chat as two debaters sharpen their counter:
Notice the architecture: 많긴 많건만 grants the data before turning on it, 아무리 급하기로서니 accepts the excuse and strips its force, and 안 뚫렸으련마는 sighs over the avoidable gap. Concede fairly, then counter — that is a Korean rebuttal.
FAQ
What does -건만 mean, and how is it different from -지만? -건만 is a formal, literary connective that concedes a clause and then pushes against it: ‘X is/was so, and yet —.’ It attaches to a finite stem: 그렇게 노력했건만, 결과는 달랐다 = I tried that hard, yet the result was different. Compared with the everyday -지만 (‘but’), -건만 carries two extra notes. First, register: it belongs to written argument, speeches, and slightly old-fashioned or emphatic prose, where -지만 is neutral and spoken. Second, feeling: -건만 leans into frustration or regret — the contrast hurts a little, because the effort or expectation in the first clause came to nothing. In a rebuttal it is perfect for granting the opponent’s effort or evidence before showing it still fails: 자료는 풍부하건만, 핵심을 비껴간다 = the data is plentiful, yet it misses the point.
How do I use -기로서니, and what is the typical sentence around it? -기로서니 means ‘even granting that X, that is no reason to —.’ It concedes a circumstance only to deny that it justifies what followed, so it almost always appears with 아무리 (‘however much’) in the first clause and a 그래도/-면 안 된다 (‘still / you mustn’t’) idea in the second: 아무리 급하기로서니 거짓말까지 할 필요는 없었다 = however urgent it was, there was no need to go as far as lying. It is sharper and more formal than -더라도 (‘even if’): -더라도 simply allows a hypothetical, while -기로서니 actively rejects an excuse someone has offered. That makes it a precision tool in rebuttal — you accept the premise (yes, it was urgent) and then strip it of its power to excuse (but that does not justify the lie).
What nuance does -으련마는 add that a plain guess like -겠- doesn’t? -으련마는 expresses a presumed outcome together with regret that it did not, or will not, come true — ‘it surely would be X, but —.’ A plain -겠- just estimates (자리가 있겠다 = there are probably seats); -으련마는 estimates and then mourns the gap between that likely outcome and reality: 조금만 일찍 왔으면 자리가 있으련마는 = if only they had come a little earlier there surely would have been seats, but (they didn’t, so there aren’t). The trailing 마는 (‘but’) is doing the wistful work, leaving the disappointing real situation implied. In argument it lets you grant that something could reasonably have been true while pointing out, with a sigh, that the facts went the other way — a graceful, slightly literary way to concede and counter at once.
